----------------------------------------------------------------
Ok I have to investigate that, aclass should not be null, but do a quick fix...
the reload on components only can happen anyway if the component tree is built
cleanly anewa instead of going through a post lifecycle from the same page
(that is expected behavior, due to the restore mechanism in the component which
gets out of sync with the components attributes)
So the fix wont break anything.
I will investigate the error on friday when I can work on the project again, so
please leave the bug open!

the reload on components only can happen anyway if you do a full refresh on the
page (that is expected behavior)
