Re: GWT: CheckBoxCell and Selection change event

Perhaps the question is not yet clear, I will try to rephrase it :

We are trying to create a DataGrid with editable cells, in which one of them is CheckBoxCell.we are using selection model as SingleSelectionModel .
Now this CheckboxCell takes two arguments in its constructor, i.e.

/**
   * Construct a new {@link CheckboxCell} that optionally controls selection.
   *
   * @param dependsOnSelection true if the cell depends on the selection state
   * @param handlesSelection true if the cell modifies the selection state
   */
  public CheckboxCell(boolean dependsOnSelection, boolean handlesSelection) {
}


Now after adding this CheckboxCell to one of the columns of the grid, it gets rendered with no problems.
But the following issues are noticed :

1) Here while adding the CheckboxCell we with no parameters with in the CheckboxCell constructor we get SelectionChangeEvent gets fired correctly, but in order to check/uncheck the checkbox we have to click twice on the check box cell. 
2) And while using

                Column<T, Boolean> checkCellGridColumn = new Column<T, Boolean>( new CheckBoxCell( false, true ){

SelectionChangeEvent is not fired.

What should be done so that I can get the check box checked at just one click and the selection event should also be fired on that click on the check box cell.

Thanks.

When I use this and click at any place in the row, selection change event does not fire and I am using Single selection model .

When I use,

    CheckboxCell();

Selection change event fires on the row but,
1) We have click twice to check or uncheck the check box cell.
2) if we check or uncheck in the checkboxcell, the value will reverted as soon as I click anywhere.

I am trying to figure out the solution, but not successful yet. Any help would be appreciated.

Am using  GWT 2.4.0
