• CRUD operations.

  I create crud operations in a workflow.

  

  When I'm clicking addJob, fragment works. The question is: if I did not build all the data, and in my opinion 'read only table' that show all the data. I found the new, blank record added.

  

  That is why I sequence in entity on pk.

  How do I manage so no data and click back2, no added record?

  My version of Jdev is 12.1.3

  You mean to delete the line? Then 'delete' would be the method.

  Or you can use the rollback method. However, the rollback undoes all the changes made since the last commit. It could do more that you like.

• Manage the CRUD operations in unique transactions

  Hello

  How can I manage the CRUD operations in single transactions using JTA? While each a separate transaction operations will not be created? Please provide examples for this topic.

  Thank you.

  Hello

  Yes, the transaction manager is implemented through the Java API of the Transaction (JTA).

  The JTA includes two main interfaces for the management of transactions, javax.transaction.TransactionManager and javax.transaction.UserTransaction.

  See: transaction manager

  And to use transactionManager, you need to inject exactly as you said.

  Why do a bit better with Demarcation of Transaction:

  TransactionDemarcation td = new TransactionDemarcation();
  boolean rollback = true;
  try {
    td.begin(getTransactionManager());
   // all changes in items of repository
    rollback = false;
  } catch (TransactionDemarcationException e) {
    throw e;
  } finally {
    try {
    td.end(rollback);
    } catch (TransactionDemarcationException tde) {
    throw tde;
    }
  }
  

• Is it possible to use workflows to Train for the old masters in detail for CRUD operations

  Hello

  I use Jdev 11.1.2.3

  I have a use case of the implementation of paintings by master detail (a master and 3 Details) and I want the CRUD operation will end only when all the data are introduced. It is therefore possible to use workflows to train for this use case.

  Thank you

  The pb is solved, I just replace the Taskflow newPersonalDetail by a simple point of view and for the createInsert I am using invokeAction in the pageDef:

• ADF Table with CRUD operations in the form of the ADF

  Hi everyone and thank you in advance for your help,
  
  I am running JDev 11.1.1.6 and I do not know how to perform the following requirement:
  
  I have two tables in a solution of master / detail : selection of a row in the primary table, made of the related lines available (according to a FK) of the secondary table. Well, for editing, I have a button in each row of a column that contains this set up and works great:
  
  Button = > showPopUpBehaviour = > popup = > dialog box:
  
  
  + < af:popup id = "p1" +.
  + popupFetchListener = "#{popUpEdit.editPopupFetchListener}" +.
  + contentDelivery = "lazyUncached" > +.
  + < af:dialog id = "d2" title = "Title" +.
  + affirmativeTextAndAccessKey = "#{rcdcontroladorBundle.GUARDAR}" +.
  + cancelTextAndAccessKey = "#{rcdcontroladorBundle.VOLVER}" > +.
  
  + <! - ENTRY TEXTS - > +.
  
  + < / af:dialog > +.
  + < / af:popup > +.
  
  The bean code is:
  
  + ' public void editPopupFetchListener (PopupFetchEvent popupFetchEvent) {+
  + If (popupFetchEvent.getLaunchSourceClientId () .contains ("cbInsert")) {+
  + BindingContainer bindings = getBindings(); +
  + The OperationBinding OperationBinding = bindings.getOperationBinding ("CreateInsert"); +
  + operationBinding.execute (); +
  +}+
  +}+
  
  But for new records, I can't manage to put the dialog box with a new record (there is an id autonumeric) and to allow the user to fill in the fields and submit. This would be the condition but I couldn't get there. I could do:
  
  Button (Action Listener): + #{bindings. CreateInsert1.execute} +.
  
  Subsequently, the user can use the option Edit in the inserted row and commit.
  
  
  I searched a lot, but I found solutions were to forms or Table CRUD implementations, not a combination of both. For this reason, I would appreciate your help. If you need additional code, more information or anything else, ask me and I will answer as soon as I can.
  
  
  Thank you
  Mariano.

  Is your question when you create a new record, it is open in a doll to go into the details... If so write code to create a record in create button Actionlistener and opens the popup programtically which may help you... If I'm your problem writing...

  Here is the code for the button actionlistener

  BindingContainer links = getBindings();
  OperationBinding operationBinding = bindings.getOperationBinding ("CreateInsert");
  operationBinding.execute ();

  then the opening of the progranmatically popup code...

  I have a question I see two different methods, you call in the Actionlistenr button you have CreateInsert1 and in the popupfetch, you CreateInsert... do you have two method actions. ?

  Button (Action Listener): #{links *. _CreateInsert1_.execute}

  Probably it could help you...

• Problems on master detail CRUD

  Dear all,
  
  I'm trying to understand how ADFBC manages the relationship master detail like this
  is the first time where I need to manage the table relation.
  Practice, I only used a table but this time I need to manage the relationship, too.
  
  I have two tables that follow. They have a to-many.
  PART_ID in the PARTS_CODE table is filled by a sequence of DB.

  PARTS_CODE                                   PART_DESC
       - PART_ID (PK)                              - PART_ID (PK)
       - RANGE                                   - REGION  (PK)
       - CATEGORY                              - DESC

  Use case is like this:
  Table PARTS_CODE contains data on the parties while PARTS_DESC contains information on the description of the specific region of the parts.
  
  Now, I created a View object that links the two tables. Then I drag this display object from
  my data as a control table update-able.
  
  I just have a few questions on the implementations:
  1 when I drag and drop the CreateInsert button and click on it, I noticed that it adds a new line to the
  table, but I noticed that it creates the Text Input component only on the associated columns
  the PARTS_CODE Table, the other columns for the PART_DESC does not have the user interface components.
  How to solve this problem?
  
  2. how to manage the relationship such that when it inserts the data on the PARTS_CODE, I need
  to get the DB generated sequence number and put it in the PART_DESC table
  
  3. any demonstration/links which shows the CRUD operations involving arrays of master detail?
  
  I searched the forum for Crud master / detail, but I can only see the display of the relationship and not
  CRUD operations.
  
  Found this blog too http://andrejusb.blogspot.com/2009/03/create-operation-for-master-detail.html, but
  I can't even fully understand.

  Thank you

  You will need to create a black and white view link in your main table and details. The blog provides the code example if you step through the code, you will get to know exactly how it's done.

• NULL values for some elements of the XML reading tree

  I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

  Example XML:

  
      1.0.0.0
      1000
      MyAppsName
      
          
              1000
              userDefined
              StructName
          
      
  
  

  And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

  In DataManager.hpp:

  QVariant mCustomDataStructsTopLevel;
  QVariantMap mCustomDataStructsTopLevelMap;
  

  In DataManager.cpp:

  mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
  mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
  
  qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
  qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
  qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
  

  OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

  The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

• RecordStore object in the device

  Hi, I'm having a problem using RecordStore object in the device. I use the RecordStore object to store the user profile.

  I have a button on the screen and when I press the button I store data in the RecordStore and another button to get the same stored data. When I run the app in the Simulator, it gives me the expected result, but when I run the app even in the unit, after pressing button Save I have to restart the application to be able to get it back. Also sometimes despite restarting I'm not able to get the saved data.

  I use the following code snippets to save and retrieve data:

   public void addValue(String key , String value)
      {
  
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      DataOutputStream outputStream = new DataOutputStream(baos);
      try {
          outputStream.writeUTF(key);
          outputStream.writeUTF(value);
      }
      catch (IOException ioe) {
          System.out.println(ioe);
          ioe.printStackTrace();
      }
  
      byte[] b = baos.toByteArray();
      try {
          recordStore.addRecord(b, 0, b.length);
      }
      catch (RecordStoreException rse) {
          System.out.println(rse);
          rse.printStackTrace();
      }
      }
  
      public String getValue(String key)
      {
          String mainVal = "";
  
      try {
          RecordEnumeration re = recordStore.enumerateRecords(null, null,
                                  true);
  
          try {
              while(re.hasNextElement()) {
              int id = re.nextRecordId();
              ByteArrayInputStream bais = new ByteArrayInputStream(recordStore.getRecord(id));
              DataInputStream inputStream = new DataInputStream(bais);
              try {
                  String key1 = inputStream.readUTF();
                  String value = inputStream.readUTF();
  
                  if(key1.equals(key))
                  {
                      mainVal = value;
                  }
  
              }
              catch (EOFException eofe) {
                  System.out.println(eofe);
                  eofe.printStackTrace();
              } catch (Exception e) {
                  e.printStackTrace();
              }
              }
          }
          catch (RecordStoreException rse) {
              System.out.println(rse);
              rse.printStackTrace();
          }
      }
      catch (RecordStoreException rse) {
          System.out.println(rse);
          rse.printStackTrace();
      }
  
      return mainVal;
      }
  

  Hello

  Only, I solved the problem. The reason for strange behavior was that I was not closed RecordStore object after the CRUD operations. I added record.closeRecordStore () at the end of each method, and now it works fine for me.

  Thank you for your interest to solve my problem.

• Popup dialog jumps around - bug or the way it is?

  JDeveloper 12.1.3

  I use dialog boxes popup for most of the CRUD operations and although I noticed this before, didn't bother me much until users have started to complain. What happens is that once the popup opens and its content is rendered (say the entry form), once the user advanced mouse above him, he jumps to an inch or two down. Users are used to until recently.

  Enforcement purposes was to have their word forms with the table in the pop-up dialog box. Several fields in the form have autosubmit = true and table refreshes when the user enters these values. Each time updating the table, the entire popup moves an inch upward or down on the screen. Very annoying, user continues essentially to set the cursor entry field. I can possibly understand that when the table updates and replaces the number of lines, the popup is reduced to the new height. But of course I expect that only the lower part "moves" that is to say that the top of the pop-up window is pinned to the whatever the screen position that it was.

  No idea how to prevent this?

  I looked in your sample. I don't see a bug here. Your layout is not just right. As far as I can see the jump is the result of too little dialog box. This translates the scroll bars added to the dialog box that allows you to jump. your dialog box has two child components. If you put them in a parent for example a stretch Panel layout, you get the best result. The I would set the size of the dialog box to a fixed value. This prevents the jumping.

• Create button on af:table creates a line empty but made salient ranks

  Hello

  I use jdev 12 c and performed a CRUD operation and found that whenever we click on create button, a new line is created, but the highlight is on another line.

  Is the way that it does or it can be changed because I need to highlight on the empty line created when the click on the button create.

  Thank you

  Abhijit

  CreateInsert operation creates the new line and add it to the collection, and then set this new line as the current line, so it appears as selected (use createInsert)

• Unable to display data from database using persistence mobile A-team

  Hello

  We use the accelerator of persistence for Mobile A-team with application of the MAF. We built the REST services based for CRUD operations on a table. We are unable to use the POST CREATE service by application of the MAF. We tried using saveTask and addTask data control methods it generates automatically. Although it is saved locally to the iterator of data control, it doesn't push the data from database. We tried to test the service REMAINS independent and works well.

  Can anyone help regarding if lack us measures in the same?

  Thank you

  Vignesh

  Vignesh,

  Indeed, there are two issues here:

  -the attributes of the payload are different

  -the structure of the payload is different, the GET request has an attribute "Task" that returns an array, the POST request submitting a single object through the attribute "taskDetails.

  By default, the accelerator of persistence assumes that the POST request has the same payload structure and attributes as the GET request that you used to 'discover' the data objects.

  However, you can easily change this as follows:

  -To add additional attributes required in the POST, you should restart the wizard REST-JSON directly access the data object attributes screen and click on the button 'add an attribute '. Add each attribute you need in the POST request and the attribute name to the value required in the POST request payload. No matter that this attribute of the payload does not exist in the payload GET, it will be ignored during extraction of the tasks.

  -To fix the second issue, you must change the persistence - mapping.xml:

  -go to the createMethod task

  -Remove the payloadElementName attribute

  -Add the payloadRowElementName attribute and set the value to "TaskDetails.

  It's a little strange that you post in order to get other attributes, it is there another resource GET that returns all attributes for a task?

  In addition, you cannot derive columns audit as created_by on the server-side? It's a bit unusual set these values at the level of the customer.

  Steven.

• AfterCommitException of blocking and cancellation

  Hello

  I use to manage the operations CRUD JDeveloper 11.1.2.1 and popups. Recently, I have experienced several afterCommitExceptions. I have the management of errors during the validation operation is performed:

  	OperationBinding operationBinding = bindings.getOperationBinding ("Commit");
  	operationBinding.execute ();

  	If (! operationBinding.getErrors () .isEmpty ()) {}
  	manage errors
  	List errors = operationBinding.getErrors ();
  	Logger.severe (Errors.get (0).) ToString());
  	operationBinding = bindings.getOperationBinding ("Rollback");
  	operationBinding.execute (); return; }

  I have a doubt about what happens when this exception occurs, and then I run a restore. On the other hand, what happens when afterRollbackException is thrown during this process? What is the status of the transaction and data?

  He's just run when rollback commit exception occurs? What is the best way to manage these errors?

  Thank you

  Exactly. Great, you're able to go forward.

  CRUD operations in pop up as you suggest it in your use case must be caring and requires extra attention.

  With the help of workflow will be much cleaner and better approach.

  Thank you

• Fusion EOs Application Customization

  Hi team,

  I have a requirement where I need to keep track of all CRUD operations performed in Application of Fusion for a specific table.

  I have a knowledge of Oracle ADF and I believe I can do use maps of history present in OE to follow last_update/modified by or create corporate event on seeded oracle fusion EO but do not know how that can be used in the merge request.

  What Version of Jdev would be compatible for the merger Appltn.

  Any guidance will be highly appreciated.

  Thank you, Ajay

  Hi Vik,

  Yes.

  I know that we can use DB triggers, but then I wanted to create a business event where I can publish this (who put day/change data) information on webservice to the help I can get XML data to generate my reports about this.

  I was not aware of which Jdev Version would be compatible with the Appltn merger. ? but then I had access to https://blogs.oracle.com/fadevrel/entry/jdeveloper_and_fusion_applications_explained who helped me get started.

  I'm stuck at, now I am not able to add a business event for which I've created a post separate pls help more (Impossible to customize LedgerSetEO of Fusion Apps) and we can close this thread.

  Thanks for the reply.

• DataControls to consume the application and the library working individually ADF

  Hi all

  need advice.

  JDev 11.1.2.4

  Integrated WebLogic

  My requirement:

  I want to create a reusable component that I can use in different applications. This reusable component must have a table ADF wherein I can do CRUD operations based on an input value.

  For this I created an ADF with stubborn taskflow application that has input parameters.

  I created the EO, the VO and her I'm in the model layer and controls using data, I created the table of the ADF inside the stubborn taskflow jsff page.

  I have a method call before the page to make the pre treatment.

  I created the ADF of Jar file library of the ViewController project with the release of generation of model project.

  I added this ADF Lib pot file to the consumer through the range of resources demand.

  Usage application has its own control Module of the Application data.

  So now, in the consumer application, I can see the two data controls, second in the ADF lib pot.

  I have a page in the application consumer with two things,

  1. a form I created using the control data of the Application Module consumes,

  2. a table I created using the taskflow bounded as a region of ADF library Jar file,

  Now am not able to save the form data and the table using the data control consume Application Module validation operation. Using individual validation operations, they work. Having said that, that my request has two working both datacontrols that says two transactions.

  My question is, if the approach I took for my requirement is correct or not. If not, please give me the right to another approach help me with the solution to my problem.

  Please let me know if you want more details.

  Thank you

  BSBhat.

  If you do not want to use individual validation operations then you must use 'management of the transaction ADF task flows', you can define under options on your narrow-minded taskflow and test your usecase.

  -> set Transaction "always start the new transaction.

  -> set Taskflowreturn component > behavior > final commit Transaction property.

  This will take care of transactions for the AM of the same application and AM of the ADF libraries.

  I hope this helps.

• PrimaryIndex County

  I have a doubt about cache.

  The environment is transactional and configuration options by default.

  I have primary Index like this:

  private PrimaryIndex < Long, EnSomeEntity > pkSomeEntityById;

  I save on it on elements of 100000000 (100 million) .

  A huge amount of data about 80 GB of data.

  1- I did a count on it he returns the number of items 100 million but id delayed by 15 minutes.

  How I did it:

  pkSomeEntity.count ();

  2- I did the countdown again once and he returned in 8 seconds.

  3- I restart the machine. now, I did count on that he delayed 15 minutes again.

  4- I did the sarch again (after the restart) the returned in 8 seconds.

  This cache is managed by the Berkeley DB or is the Disk Cache. (the disc isn't DDD, this is a 'normal' SATA).

  What is the best way to manage the cache with this huge amount of data?

  For most of the CRUD operations you perform, the size of the cache I is important because the internal Btree is cached.  See the DbCacheSize utility to find out how to estimate the optimal size of this cache.  For this big one set of data, you'll need a great cache I to get a decent result.

  However, for the count () operation, cache I is not used.  In this case, the file system cache is more relevant to performance.  In your example, it is likely that the file system cache is be filled when you first call count(), and then it's faster the second time you call it.  The count () operation is very expensive because internal Btree does not maintain a number of records.  For this large a set of data, I do not recommend to use it.

  Please be sure to post the version of BDB I that you use when ask you a question.
