Programmatically setting selected row on a table.

2750374Apr 24 2017 — edited May 1 2017

Im working with Jdeveloper 12.1.2.

I have a table based off a view iterator. On this table a have a custom Selection Listener. When the user selects a different row from the table it first checks that the required actions have been completed before allowing the user to change rows. This works in that it doesnt actually change the current row in the iterator, but the table will still highlight(select) the new row. Is there a way to set the selected row on a table?

This is what i have for the selection listener.

  1. public void tableSelectionListener(SelectionEvent selectionEvent) { 
  2.     String checkAllow = checkAllowFunc(); 
  3.          
  4.     if(checkAllow.equals("good")){ 
  5.             ADFUtil.invokeEL("#{bindings.testTableVO1.collectionModel.makeCurrent}", new Class[] {SelectionEvent.class},new Object[] { selectionEvent }); 
  6.     } 
  7. } 

Do i need an "else" with some specific code to revert the select? I hope that makes sense.

I would normally do my validations checks in the BC layer(as a business rule) but in this instance thats not an option.

Try setting the blockRowNavigationOnError to always and throw validation exception from your check method.

Do what Timo suggests for details check - Blocking row navigation in af:table , synchronize row selection with model in case of validation failure- Oracle ADF – A…

Hmm not sure if im missing something but the table is still allowing me to select a new row when its failing my validation check. Am i missing something with throwing the validation exception?

I set the block row navigation property to always on my table.

     blockRowNavigationOnError="always"

and i altered my function like so adding the throw validation exception.

  1. public void tableSelectionListener(SelectionEvent selectionEvent) { 
  2.  
  3.     String checkAllow = checkAllowFunc(); 
  4.  
  5.     if(checkAllow.equals("good")){ 
  6.             ADFUtil.invokeEL("#{bindings.testTableVO1.collectionModel.makeCurrent}", new Class[] {SelectionEvent.class},new Object[] { selectionEvent }); 
  7.     } 
  8.     else{ 
  9.         try{ 
  10.             throw new ValidationException("TEST"); 
  11.         } 
  12.         catch(Exception e){/*IGNORE*/} 
  13.     } 
  14. }

User do like this

public void selctListener(SelectionEvent selectionEvent) {

   //Getp previous selected row key

  RowKeySet oldKeySet = selectionEvent.getRemovedSet();

  RichTable table = (RichTable) selectionEvent.getSource();

   if (1 == 2) {

  invokeEL("#{bindings.DepartmentsVO1.collectionModel.makeCurrent}", new Class[] { SelectionEvent.class }, new Object[] {

  selectionEvent });

  } else {

  

  table.setSelectedRowKeys(oldKeySet);

  AdfFacesContext adfFacesCtx = AdfFacesContext.getCurrentInstance();

  adfFacesCtx.addPartialTarget(table);

  FacesContext fctx = FacesContext.getCurrentInstance();

  fctx.addMessage("Wrong Move", new FacesMessage("Can not select new row due to validation failure"));

  fctx.renderResponse();

  }

  }

replace if(1==2) with your condtion if(checkAllow.equals("good")
