this works, dispatch a fake event and change it, what happens is the
TabNavigator either loses focus or the children are not garbage collected until
there is a click or some form of interaction with it

{
var v:VBox = new VBox();
v.label="Tab" +String(i);
myTab.addChild(v);
}
myTab.dispatchEvent(new IndexChangedEvent(IndexChangedEvent.CHANGE));
myTab.selectedIndex=0;
}

Subject: [flexcoders] TabNavigator weirdness
I have a TabNavigator component that I completely reset the tabs
dynamically with the following code:
tabNav.removeAllChi ldren();
for each (var container:Container in myList )
{
tabNav.addChild( container)
}
tabNav.selectedInde x = 0;
So this successfully removes the existing tabs, then loops though my
ArrayCollection and adds a new set of tabs. It also shows the
contents of tabNav[0], but the tab that displays as selected is
whatever was currently selected. So if I originally displayed the
tabnav and clicked the 3rd tab, then clicked the button completely
outside of the tabnav that causes it to redisplay, it will correct
show the contents of tabnav[0], but visually it looks like the 3rd tab
is still selected.
I also tried tabNav.validateNow( ) and it doesn't work. To test I
added a button completely outside of the tabnav with
click="tabnav. selectedIndex= 0", works great.
So what am I not doing?
Thanks,
Dale
