Hi,

I dont have info about that concrete situation, but as I know java gui api, 
there should be some function called "revalidate()" which should do 
revalidation also on parent components. So try to override this on core 
panel, than from overriden method call original revalidate 
(super.revalidate()) and than your updateMeta().

There are also AspectJ (ascpect programming paradigm) which could solve this, 
but imho this is not right solution.

I hope revalidate, or paint or some update function overriding should help.

GL and pls post also final solution to this mail thread.
