Issue with custom Item renderer data repainting or data change automatically after focus out

"Issue with custom Item renderer data repainting or data change automatically after focus out".

There are lot of developer who creates custom Item renderer and place logic in side it, but lot of developer make small and common mistakes while creating custom component or custom item renderer.

If developer is overriding function he/she should take care of adding line

super.functionName(Par[..])

Example: -
override public function set data(value:Object):void
{
super.data = value;
//Developer Logic start below……
}

If developer forgot to write super in his override function above issue occurs where developer spend lot of time to find out the solution in written logical code.
