Re: Re : Re: CellTree with SingleSelectionModel will not fire event for root node (GWT 2.3)
Jens Teglhus Møller
I do have an onSelectionChange() handler but it never gets called when
the root node is clicked. When the root node is clicked i see a visual
change (small change in the background color), but not the real
selection (which defaults to a blue background).
Its only the root element that gives me trouble, when clicking
somewhere on a node below the root it works as expected and my
onSelectionChange() method is called.
And when i talk about a node being clicked, i mean clicking on the
node text (not the expand/collapse images).
Best regards Jens
