Hey, all these containers(TabNavigator, accordion etc) fire a change
event when the current tab changes.
I would add the following event handler for the creation complete event.
private function handleCreationComplete(): void
{
if(TabNavigator(this.parent).selectedChild == this)
{
handleTabChange();
}
else
{
TabNavigator(this.parent).addEventListener('change',
handleTabChange);
}
}
In the handleTabChange(), I would check if this is the first time this
child is visible by maintaining a class level variable and set it to
true the first time this function is called.
HTH.
