the problem that i have is that i use a gwt-ext panel and then i add
to it an image component
from gwt. so when i want to use the getComponent method of the panel,
i can only cast
to component that are from gwt-ext, if i try to cast to a gwt
component it throws the cast exception
I cant use that way ben because i add componentes dynamicly, i dont
have a reference to the
object but only the position in component array of the panel.
