GridPanel CheckBox Header
Hello!
I have a GridPanel with CheckBoxSelectionModel with a listener that disables rows with specific column value.
For this test case I disable all the rows with a negative "Change" value.
The problem with my code is when I click the CheckBox header to select all rows, the header state won't toggle to selected. Thus, I can't perform deselect all action.
Am I missing something?
