• LOV in richeTableau resets the value after the deletion of rows from the table

  Hello. I'm on 11g R2

  I have a table with columns in the box and a button in the toolbar that removes the lines checked

  I have build it based on the following article in her string code

  http://www.Oracle.com/technetwork/developer-tools/ADF/learnmore/index-101235.html

  
  

  When I run the "delete" button I execute the following code (taken as is article)

  
  

  public void deleteSelectedRows() {}

  create a second line, the value do not affect all lines

  used in ADF

  Set of rows duplicateRowSet = this.createRowSet ("duplicateRowSet");

  first row to avoid "the attempt to access the value of lines."

  exception line was dead.

  duplicateRowSet.first ();

  retrieve the current row of the table for after

  re-running the VO

  Line currentRow = this.getCurrentRow ();

  Boolean currentRowDeleted = false;

  get all rows that have the transoent attribute

  "MarkForDelete' set to true

  Row [] rowsToDelete =

  duplicateRowSet.getFilteredRows ("MarkedForDelete", true);

  If (rowsToDelete.length > 0) {}

  run only throizgh this code, if there is something to

  delete

  for (line rw: rowsToDelete) {}

  If the row is marked as the current in VO, ts value

  Boolean flag

  If (rw.getKey () .equals (currentRow.getKey ())) {}

  currentRowDeleted = true;

  }

  remove the line - do not yet commit

  RW. Remove();

  }

  rerun VO

  this.executeQuery ();

  reset the current line if it has not been removed

  If (! currentRowDeleted) {}

  this.setCurrentRow (currentRow);

  }

  duplicateRowSet.closeRowSet ();

  }

  }

  "MarkedForDelete" is a transient attribute used to mark the line delete

  The lines are removed very well.

  The problem is with lines that I do not delete.

  For example I LOV column. I chose the value LOV in a few lines, and after that choose to delete several lines (not the same lines where I modified the LOV) but some other lines.

  After I click "delete", the lines that I marked to remove deleted indeed, but the value of the LOV in other rows (I have not scored for delete) are disabled.

  How to preserve value LOV so it will remain also after I deleted some lines?

  P.S. I've tried autosubmit = "true" - it did not help

  It is expected because I see that you rerun the query.

  Once you re - run, it retrieves from the database again. Thus, your values are lost because they are not posted.

  I don't think that run query is necessary, try to have a programmatic part trigger on the table after you remove all of the lines.

  Thank you
