Description

Changing the buttons 'fonSize' style at runtime by e.g. using a slider has no effect:

<s:HSlider id="sdFontSize"  minimum="10" maximum="500" />
<s:Button id="btn" label="test" fontSize="{sdFontSize.value}"  />

I've tried to fix this and found that moving the 'fontSize' population from 'initializationComplete()' to 'updateDisplayList()' works like a charme:

override protected function initializationComplete():void
{
...
// Set 'fontSize' here cause doing this inside the 'labelDisplay' results in an error
// labelDisplay as Label).setStyle("fontSize", fontSize);
...
}


override protected function updateDisplayList(...) : void
{
...
super.updateDisplayList(unscaledWidth, unscaledHeight);
				
// Set 'fontSize' here cause doing this inside the 'labelDisplay' results in an error
labelDisplay as Label).setStyle("fontSize", fontSize);
}

Cause I'm not a 'high level' Flex programmer I don't know if doing this results in other bugs.
