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(); } }; -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
