• [ADF, JDev12.1.3] Model engine SelectOnChoiche should auto filling when it contains only 1 item

  Hallo,

  I have a model piloted by selecting a Choiche UIC LOV (in VO) is set up with enter any selection point = Point Blank (the first list).

  Well, I'd like that when the SOC contains 1 single element element is automatically selected.

  It is possible to achieve and, if so, how?

  Thank you

  Federico

  Well, maybe you can create the ViewRowImpl class and override the getter for this attribute...

  Something like this pseudocode:

  public SomeType getSomeAttribute(){
      Object value = getAttributeInternal(ATTRIBUTE_ID);
      if(value == null){
          if(getLOVAccessor().getEstimatedRowCount() == 1){
              value = getLOVAccessor().first().getAttribute("LovAttrib");
              setSomeAttribute(value);
          }
      }
      return value;
  }

• [ADF, JDev12.1.3] How to get the column headers, request of VO and VO bind vars used by an af:table?

  Hallo,

  I want to create a method that takes as a parameter the id of an af:table (used to display the search results) and returns:

  • the column headings of the af: table
  • Visible property (true/false) of the columns af:table
  • the actual query of the VO instance used to create the af: table
  • the values of real bind variables passed to the query of the instance of VO

  I would like to create a servlet which takes the parameters reruns the query and returns a report Excel/PDF file that contains exactly the same columns and same of the af records: table.

  I'm a little confused on who use the code to achieve this... you kindly help me?

  I did a similar qustion here Re: [ADF, JDev12.1.3] how to export an af:table to Excel in an ADF Essentials application? but then I guessed that it was preferable to create a new thread.

  Thank you

  Federico

  For this, you can use this type of code

  Context LocaleContext = _adfTableBinding.getLocaleContext ();

  for (attr AttributeDef: attributeDef) {}

  Label As String = attr.getUIHelper () .getLabel (context);

  _logger.info ("Attritbute name:" + attr.getName () + "column name:" + attr.getColumnName () + "Col4Query name:" + attr.getColumnNameForQuery () +)

  "Name:"+ label);

  }

  which produces this output

• [ADF, JDev12.1.3] When you use create/restoreSavepoint... Restore operation is still useful? And other doubts...

  Hallo,

  Dario and Timo advised me (in this thread Re: [ADF, JDev12.1.3] Master w/playback af:form only af:tables detail: how to handle insert and edit through forms?) I make a request using the functions create/restoreSavpoint to this fragment in my application.

  

  The tables are read-only, and the user can insert and modify records by a form of popup.

  Each table has its own pop-up that I created using a btf executed as diaolog (*).

  Before I open the popup, I create the backup point.

  BindingContext bctx = BindingContext.getCurrent();  
  DCDataControl dcDataControl = bctx.getDefaultDataControl();  
  String sph = (String) dcDataControl.createSavepoint();  
  AdfFacesContext.getCurrentInstance().getPageFlowScope().put("AdfmSavePoint", sph); 
  

  When the popup is closed, I restore the backup point if the Cancel button was clicked...

  Object confirmOrCancel = returnEvent.getReturnValue();  
  if (((String) confirmOrCancel).equals("cancel")) {  
    String sph = (String) AdfFacesContext.getCurrentInstance().getPageFlowScope().get("AdfmSavePoint");  
    BindingContext bctx = BindingContext.getCurrent();  
    DCDataControl dcDataControl = bctx.getDefaultDataControl();  
    dcDataControl.restoreSavepoint(sph);  
  } 
  

  I have these doubts:

  1. the button "CANCEL ALL" (so far) AM restore operation is still meaningful (is always useful) when you use the check points? Or can I avoid using the restore of the AM operation, creating a backup point before you enter the fragment and restore it if the user clicks on "RESTORE ALL"?
  2. for all tables: before opening the popup insert/change the backup point is implemented pageFlowScope under the same key 'AdfmSavePoint '. Is it OK or would it be better to use a different key for each table (for example 'AdfmSavePointTable1', 'AdfmSavePointTable2',...)?
  3. If the pageFlowScope already contains a checkpoint under the "AdfmSavePoint" key... What does if I give the floor to new .put ("AdfmSavePoint", sph)? Can I be sure that the old value is overwritten?
  4. is this safe with nested savepoint? For example in my case I want to create a backup before the fragment in the image point is displayed (and restore if the user leaves the fragment by clicking "RESTORE ALL"), then within the fragment, as I said above, I would manage other points of record when inserting/editing tables.
  5. I noticed that clicking on the button "RESTORE ALL" when it relates to the AM-restore operation causes this strange thing: when before displaying the fragment I call SetCurrentRowWithKey on the master istance VO... If I click on "ROLLBACK ALL" posted master VO Records changes and 1 minutes of the main of the VO table is displayed. Why the master istance VO is not reimain in the folder I've previously selected by SetCurrentRowWithKey?
  6. With reference to the expression (*) above. The BTF 'dialogue' I created contains only the page jspx with shape and a return to activity. I also tried a) create (and restore) the backup point, b) to call createInsert inside the "dialog box" operation BTF (see images below), but the createInsert on retail VO istance called inside the 'dialogue' BTF seems not to reflect on the table as when I call createInsert by calling btf. I have to make some adjustments in the 'dialogue' of BTF?

  

  

  Thank you

  Federico

  Federico,

  (1) Yes, what should happen if a user add or edit vo1 and click ok in the dialog box but decided that ask to work must be restored?

  (2) as long as you don't have that a dialog box is open, it should work.

  (3) the flowrate range of page is a map. You can put the same key more than once. If the key already exists, the value is replaced.

  (4) in fact, I don't know, but the sounds of complicated design. I guess you can record more points, but only in the order of creation. It's as if you try to rebuild the framework. BTF yo it even for you, when worn right. Please go to ADF Architecture Square and read and watch it task flow of related things.

  (5) this behavior is as expected. A restore resets all the iterators so thagetto point at the top of he. http://www.Oracle.com/technetwork/Developer-Tools/ADF/learnmore/OCT2010-OTN-Harvest-183714.pdf 'keep the line after cancellation' shows how to handle this situation.

  (6) I suppose have you refresh the table iterator, once you close the dialog box for the new data. But that's only a guess because it depends on how the btf share control of data and the your involved.

• [ADF, JDev12.1.3] Which is the best way to define the properties of CIU/fragments of pages. Is the approach that I have used a good choice (for a beginner)?

  Hallo,

  in my app, that I have a lot of pages and fragments in which properties (for example rendered text, disabled, Selected,...), lots of user interface components must be set, before/when the page is displayed, depending on the session and pageFlow scope attributes.

  So far I have created for each page/one backingBean brought bean fragment in which I defined an attribute for each property defined (e.g. 2 properties for each UIC: UIC is 10...) "I have 20 attributes to manage in the bean).

  Then, I linked each attribute of the bean to the respective UIC property. You can see in this my thread (unfortunately without answers ) [ADF, JDev12.1.3] backingBean bean: a lot of properties to set for lots of CIU... is better by using the properties of the binding or access code (created by ID) UIC? a small example. I put the attributes the bean Builder (or in a function of 'action' if the APP properties must be set based on the interaction of the user).

  I would like to know:

  • If it is a good approach / recommended / safe or if there is a better way;
  • If the scope backingBean is OK, or if a larger scope would be better.

  As I asked in the thread in the link above, the situation can become difficult to manage if the PPP for which setting, properties are very different.

  So I'd like if there is no alternative that I can use to get the same result with less effort.

  For example, using the class ComponentReference or invokeOnComponentAPI could simplify my life? And their use could I always use backingBean brought beans?

  Thank you

  Federico

  Federico, please understand that this forum has no sla. I have other work to do, who pays my bills. I will do my best to help, but you can not expect the instant replay.

  (1) you must not use the bean to init your beans. You can delay load or init your beans instead.

  (2) as Frank and says you can use a bean to view range and use it to make your calculations as long as you know how their parameters go to the btf

  (3) you should always use the reference of the component if you bind a component to a bean. Make a habit of all scopes.

  As we do not know how you calculate the State and how often it changes while the Working Group is on the page, it is difficult to give further advice.

• [ADF, JDev12.1.3] master / detail af:tables the link is handled by ExecuteWithParams: how to create a master report / detail in a loop on the lines?

  Hallo,

  I have a page with 2 legs and they both contains an af:table created by dragging an instance of VO in the user interface.

  The 1st tab uses a master VO while the 2nd uses a VO detail.

  Between 2 your, there is not a link of VO master / detail.

  Opening Details tab I update the secondary table by calling the method ExecuteWithParams of the detail VO instance (in a managed bean).

  I would now like to generate a report that loop on the master table and that, for each line of master:

  • He writes in the report;
  • loops of registration of details (which are based on the master record) and also writes the report.

  
  

  Could you kindly suggest me which is the best way to achieve that through a code to write in a managed bean?

  Here I am interested how do to loop through the data, not in how to write the report.

  Yes it will affect the selected line. If you want to ignore try using this code

      ViewObject vo = iter.getViewObject();
      for (int i = 0; i < vo.getEstimatedRowCount(); i++)

• [ADF, JDev12.1.3] Problem of formatting attribute VO MONEY when exports it as an Excel file using apache.poi

  Hallo,

  I have a VO with an attribute based on the field of database of MONEY.

  In the configuration of the VO for the attribute I put:

  • In the "Details" tab: Type = BigDecimal
  • In the "Indications of the UI" tab: Format type and Type like the image below

  

  These settings allow the value of the attribute (in the table, inputText) appears with thousands and decimal separator that according to my language - Italian - are. (point) and, (comma).

  For example. Silver number displayed correctly:

  10.123.000,37

  When I write the value of the attribute in an Excel cell using apache.poi...

  cell.setCellValue (attr.toString ());

  ... I see in the cell...

  10123000.3700

  ... Although I'd like to see what...

  10123000,37 (not thousands separator, the comma as separator decimal and only 2 decimal places)

  
  

  You could you kindly help me to get there?
  

  Thank you

  Federico, this isn't really a question JDev or ADF. This can be solved by setting the cell format to the cell, you write the number. Like oyu would in excel

  style.setDataFormat(HSSFDataFormat.getBuiltinFormat("#,##0.00"));

  Well, for automatic resizing, you can use this workaround: https://agungor.wordpress.com/2014/05/14/handling-un-resizable-facesmessage-popup/

  Also, if I remember correctly, you can download the fix for this problem for Oracle Support(if you have support contract).

  Inline messages you must provide the id of the component when you create messages of faces.

  For global inline messages you need to af:messages component.

  As an alternative, you can use something like this: Awasthi (Jdev/ADF) Ashish Blog: better interface user-display the notification message of jQuery (for error, warning, info) to Oracle ADF

• [ADF, JDev12.1.3] How to manage cookies (configure/create/read) in the ADF applications?

  Hallo,

  I would like to create a cookie in my ADF application.

  To start I used the code shown in this thread code example for create / read a cookie value? but the cookie seems to not be created.

  It is not present in Firebug or it can be retrieved by the code.

      Cookie userCookie = new Cookie("myCookie", "hello");
      userCookie.setMaxAge(-1);
      FacesContext ctx = FacesContext.getCurrentInstance();
      ((HttpServletResponse) ctx.getExternalContext().getResponse()).addCookie(userCookie);

  1. Cookie userCookie is new Cookie ("MyCookie", "Hello");.
