• How to assign a value of the element from page to main page in the column element when Cre

  I have a form build on table T1. The T1 has a primary key defined (T1PK) and four other columns (C1 - C4). I have a form in this table. This form accepts the values of C1 to C4 and displayis an extra point, is not based on columns of T1 - P1_DUMMY. The form for T1PK element has the value "hidden and protected.
  When creating the form, I wanted that the value of the primary key (T1PK) will be obtained through existing trigger. I want to use the value stored in the page called "P1_DUMMY" for P1_T1PK.
  
  No matter what I do, I always get this error when I hit the button 'CREATE' on the page of the form:
  
  ORA-01400: cannot insert NULL into ('DEV'. "" T1 ". ("' T1PK")
  
  The Create button is a condition not to show if the the P1_T1PK page element is NULL. I created page rendering process, the process of transformation of page like this bock of PL/SQL:
  
  : P1_T1PK: =: P1_DUMMY
  
  But I still get ORA-01400. The form has the P1_DUMMY as display only, not not to store the State, so I can see that the P1_DUMMY element has the value I want (2).
  
  How to assign the value stored in P1_DUMMY in P1_T1PK when I click on the button CREATE on this form?
  
  Thank you for your time.
  
  Daniel

  Hello
  The belief question is the way in which the calculation is being defined. You are not using the &. rating (dot ampersand) in PL/SQL and SQL.

  Try this.

  1 define the calculation on P1_T1PK of Type calculation of value of the element
  2. on the next page to load textarea, enter P1_DUMMY. No. colon or &
  3. give appropriate conditions

• ADF: How to set default values for the attributes of each Insert online?

  Hello

  I am new to the ADF. I'm developing a simple Application from merger where a column of af: table has to be displayed with the user name (default) on each insertion.

  I tried using below EL:

  < af:inputText value = "#{null == row.bindings.SalesPeople.inputValue?" "{userBean.strUserName: row.bindings.SalesPeople.inputValue}"...

  And I am able to display the logged in user name by default on the side of the user interface, but the name of the user isn't getting recorded in the database.

  The action that I used to insert a new line is "CreateInsert".

  < af:commandButton text = 'Add new record' id = "cb1" actionListener = "#{bindings." CreateInsert.execute}"partialSubmit ="true"/ >

  Please help me how to solve this problem...

  Thank you

  Alexander

  Thank you all,

  I was able to solve this problem in action appellant and here is the code snippet

• How to set the default value of the attribute with a sequence number? Is it possible to add a string to seq.no. like abc0001?

  Mr President.

  How to set the default value of the attribute with a sequence number? Is it possible to add a string to seq.no. like abc0001?

  Concerning

  For the date, you can use groovy expression adf.currentDate to set the current date. reference http://adfgouravtkiet.blogspot.in/2012/11/how-to-set-default-values-for-entity.html

  You already have ways to use the sequence.

  How do you add a new value in the form. You're creating a new line of your page (user interface) and by engaging with validation operation? Unless you commit you will not be able to see anything in the table.

• How to see the values of the attributes of global context?

  Hi friends,

  There is a context (namespace) in DBA_CONTEXT and DBA_GLOBAL_CONTEXT. But it is not available in SESSION_CONTEXT and ALL_CONTEXT. (It is only on the schema in the instance).

  The context Type is ACCESSIBLE on a GLOBAL scale. My version of Oracle's 11g 2. Please help me to find the values of the attributes of the context. Thanks in advance.

  Try to use the GLOBAL_CONTEXT instead...

  See http://docs.oracle.com/cd/E11882_01/server.112/e17110/statviews_5126.htm#REFRN29087.

• [ADF, JDev12.1.3] (How to set values for the attributes 1) to create a file and 2) committing to the database?

  Hallo,

  in my tables and forms (created from VO istances) there are some areas for which, insert and update, I calculate and set the value programmatically when a record is created or updated.

  In some cases, I put the necessary values using the 'CreateWithParams' in the workflow diagram...

  

  In some other ones, I associate an action, a bean, a created button drag-and - drop operation 'CreateWithParams' of the istance VO...

    public String cwpButton_action() {
      BindingContainer bindings = getBindings();
      OperationBinding operationBinding = bindings.getOperationBinding("CreateWithParams");
      // here I calculate and set the needed params
      // ...
      Object result = operationBinding.execute();
      if (!operationBinding.getErrors().isEmpty()) {
        return null;
      }
      return null;
    }
  

  And is ok if I can calculate the values for the attributes before a new record is created.

  But the approach that I have used to define the attributes (for new and updated records) whose value should be caluclated after the user has filled in the fields, before committing to the database?

  Thank you

  Federico

  Federico,

  Let me first tell you that our code is activity masking errors (the cache instead of working on them).

  1. If (! operationBinding.getErrors () .isEmpty ()) {}
  2. Returns a null value.
  3. }
  4. Returns a null value.

  This means that you do not check the errors at all. You must at least print a log with the error message, you receive, if you get one!

  To solve your problem, you override the method prepareForDML() of the entity or entities in question. You can calculate and set the necessary attributes until they get engaged in the doDML(). Do not use doDML() because it is too late in the life cycle.

• selectOneChoice displays the first value of the attribute

  Hi people,

  In my demo application, there are a couple of selectOneChoice drop down LOV which are based on the query based VO. The UnselectedLabel property is set to "No Selection". These LOVs are used to filter the set of query data. When the drop down menus are not called and the push of a button, the LOVs, behind the stage, have the first value of the attribute that is assigned automatically. Is there a way to ciircumvent the issue without the implementation of valueChangeEventListener?

  Thank you

  udys

  udys,

  It's not like you have implemented correctly.

  1. the error message says:

  "The class"oracle.summit.selfservice.view.HZHRLocsocBean"does not have the property"vLocvalue"

  On the screenshot, it is clear that the name of the variable is "fromLovValue" and not "vLocvalue". Please make sure you use the correct name.

• How to display a value of transitional attribute to column db entity column?

  Mr President

  Help me at the time 12.2.1 jdev.

  How to display a value of transitional attribute to column db entity column?

  I have the requirement to indicate a value of transitional attribute column in the column db entity for some reason any.

  Any body can help as my show in the picture below

  The StAmt is a transitional column and a column db of the entity.

  

  Any body can help please. !

  Concerning

  This means that the amount to be the attribute will always has the same value of the transient attribute? If so, why do you want the amount attribute the transient attribute is sufficient?

  Anyway, if you want to get attribute data in attribute transitional amounts you can open class ViewRowImpl and appearing in the getter or amount, you can get the value in the transitional as attribute:

    public Number getAmount()
    {
      return getTransientAttribute();
      //return (Number) getAttributeInternal(AMOUNT);
    }
  

  in this case, the quantity data store database will not appear on the table it will still get the transitional attribute data and it's meaningless.

• Time Dimension type to different values in the attributes - Bug or feature?

  Not sure if this is a bug or a feature.
  
  But if there is a time dimension hierarchies. You have the option of specifying different values for member attributes in different hierarchies.
  
  For example.
  
  A hierarchy has MIN_ID for its members and uses MIN_END_DATE for its end_date
  
  Hierarchy B has MIN_ID for its members and uses SESS_END_DATE for its end_date
  
  According to this message and a comment by David Greenfield:
  
  Gender issue when several mappings for different hierarchies
  
  "You try to map the same attribute, SORT, on different columns in two hierarchies? In other words, what do you expect the same Member to have different values for the attribute in the two different hierarchies? If so, then this is a problem because a member must have the same value for the attribute independently of the hierarchy. »
  
  Unlike a dimension of the user, a time dimension seems to allow this and it seems to work as expected. Behavior in this case is the difference between a user and the time dimension?

  Your description of the structure of the dimension is very clear, but I have a question about system requirements. When you say you want to the time running from 17:00 to 16:59, do you mean that the calculation must spand day? for example "5:00 PM: Jan 1, 2012" to "4:59 PM: 2 Jan 2012".» If so, then this you is impossible by making a loop only the dimension of time-seconds. Or do you really mean it must wrap around the same day. for example "5:00 PM: Jan 1, 2012" at "11:59 PM: 1 Jan 2012", then again to "00:00 AM: 1 Jan 2012" to "4:59 PM: 1 Jan 2012"?»»»

  If you want the calculation for the period of days, then I think you need to spend TIME on the DATE dimension level. You can leave some MINUTES in the second dimension, which can be a dimension of standard user. You must then two levels of the DAY (with different members) in the date dimension - each with a different set of the child. You can assign the TIME_SPAN to the TIME level 1.

• Default value for the attribute transient

  Hello
  
  I use jdev 11.1.2.2.
  
  I have added a transitional attribute to the view object.
  
  I added a adf.context.securityContext.getUserName () default value to the attribute.
  
  Since I gave him in default value display only during the Insert to create operation.
  
  But I want that it always shows the value.
  
  How can I do?
  
  
  Thank you and best regards,
  Rakesh

  The attribute can is "always"?
  Also adf.context.securityContext.userName as the default value Expression with recalculate "Always" should work fine.

• get the value of the attribute of Advanced Table &amp; set

  Hello
  
  I am a beginner in the OPS, that's why your help is very appreciated. _
  
  
  Can one advice me please how I can get and set values for the attributes in Advanced Tabel.
  
  I have an advanced array (dtls_advance_tbl) that contains 5 columns and I want to get the value of the attribute (class_1) and change the value of the attribute (class_1_image) on this basis.
  
  Please advice the code and what class / method I have to write it (I mean it is in the controller / VOImpl)?
  
  Thanks in advance.
  
  Kind regards... Ashraf

  No ok ok, so no need to go to rowreference or PPR.

  change the code below and the writeh in the PR of the extended controller method

  OAViewObject vo = (OAViewObject) getEmployeeSummaryVO1 ();
  Line EmployeeSummaryVORowImpl = null;

  This tells us the number of lines that were recovered in the
  Rowing together and away the extra lines as some of the
  other methods 'get County '.

  int fetchedRowCount = vo.getFetchedRowCount ();

  We use a separate iterator - even if we could scroll the
  the lines without it - because we do not want to influence the currency of the line.

  RowSetIterator deleteIter = vo.createRowSetIterator("deleteIter");

  If (fetchedRowCount > 0)
  {
  deleteIter.setRangeStart (0);
  deleteIter.setRangeSize (fetchedRowCount);

  for (int i = 0; i)< fetchedrowcount;="">
  {
  line = (EmployeeSummaryVORowImpl) deleteIter.getRowAtRangeIndex (i);

  For performance reasons, we generate ViewRowImpls for all
  Objects in view. When we need to get an attribute value,
  We use the accessors appointed instead of a generic string search.

  Number primaryKey = (Number) row.getAttribute ("EmployeeId"); / / Get two rows here at a time when you want to compare

  Number primaryKey = row.getEmployeeId ();

  If (make the comaprison here)
  {
  write your logic here
  break; only one selected line in this case
  }
  }
  }

  deleteIter.closeRowSetIterator ();

  Thank you

• Support of the value of the attribute?

  I would like to do something in RH8, but I don't see a way. Perhaps through variables defined by the user, but I don't really see how the variables much more than excerpts. Conditions do not seem to apply here either. I would like to define a global attribute, such as 'product '. Then, the attribute would have different values: 'ProductA', "ProductB", etc. Then, I would apply the attribute to the different topics, by selecting different values for each theme. At the end of the day, I would insert a snippet or a variable at the top of a topic, which says: "applicable products:"x, y, z"."x, y, z"would be a list of products, this section applies to.» This list may change over time, but instead of manually update the topic, I would just update the values for the attribute 'Product' section, and the snippet in the topic would update itself. Any ideas?

  Thank you. It seems that I posted this in the wrong category, so I'll mark this one as "answered" and re-post in the right place to see if I get more suggestions. I apologize for the confusion.
