Re: CheckboxCell 2 clicks for selection

Thank you very much Y2i.

I´ve got it solved. For users with the same problem:

The problem was int he logic that you have to handle in the getValue method of the column.

MyModel has a Boolean field used to represent whether the checkbox should be checked or not in the first presentation of the table. The table has to behave like this:

 - If the checkbox IS not selected and you click it, then the row becomes selected and the checkbox clicked.

 - If the checkbox IS NOT selected and you click it, then the checkbox becomes clicked (the state of the row remains unchanged, i.e. unselected).

So the logic to handle this:

    Column<MyModel , Boolean> checkColumn = new Column<MyModel, Boolean>(new CheckboxCell(true,false)) {

      @Override

      public Boolean getValue(MyModel myModel) {

      if(selectionModel.isSelected(myModel)  &&  myModel.isValid()) {

      myModel.setValid(false);

      selectionModel.setSelected(myModel, false);

      }

      return selectionModel.isSelected(myModel) || myModel.isValid();

      }

    };
