Hey there Stackoverflow,

I got a doubt regarding pre-selecting(setSelectedIndex(index)) an item in a ListBox, Im using Spring + GWT.

I got a dialog that contains a painel, this panel has a flexpanel, in which I've put a couple ListBox, this are filled up with data from my database.

But this painel is for updates of an entity in my database, thus I wanted it to pre-select the current properties for this items, alowing the user to change at will.

I do the filling up in the update method of the widget.

I tried setting the selectedItem in the update method, but it gives me an null error.

I've searched a few places and it seems that the listbox are only filled at the exact moment of the display. Thus pre-selecting would be impossible.

I thought about some event, that is fired when the page is displayed.

onLoad() doesnt work..

Anyone have something to help me out in here?

Thx in advance,

Rodrigo Dellacqua
