Re: GWT CELLTABLE How to restore old value in cell if validation fails

Its way too late but still and I think you must have already done this... Below would redraw only a single row.

dataGrid.redrawRow( rowIndexReceivedInUpdateMethod );

Hi Loan,

Thanks for your solution. It works but  Performance is too bad.
i.e clearing incorrect values for the whole row (say 5) takes too much
time(clearViewData+ redraw table)

Reverting N records will take too much time :(

Is there any fast way to update old row/object in celltable ?




 // when setting up table columns add the edit cells to this list
 List<EditTextCell> editCells = new ArrayList<EditTextCell>();
 ....

 // clear incorrect values for the whole row
 for (EditTextCell editCell : editCells)
 {
      editCell.clearViewData(KEY_PROVIDER.getKey(object));

 }
cellTable.redraw();
