Now if I override synchronizesVariablesWithBindings() in

But I see lots of examples (e.g. WOTable and WOCheckboxMatrix)
where subcomponent using the ^ don't override
synchronizesVariablesWithBindings() to return false. And I assume
that they work (I haven't tested them).
What am I missing here?
public boolean isStateless() {
return true;
}
"By default, stateless components don't synchronize. So, if you
override this method to return true and you want the component to
synchronize, you must also override
synchronizesVariablesWithBindings and return true."
Thanks a lot Chuck, this explains it.
The API docs for WOComponent.synchronizesVariablesWithBindings()
says: "This method returns false for stateless components (unless
you override isStateless and return true), and true otherwise."
Which, to this non-native english speaker, seems contradictory!
Shouldn't it read "... (unless you override
*synchronizesVariablesWithBindings* and return true)?!?
I read that several times. It is nonsensical. The correct statement
would be something like this:
This method returns false for stateless components and true
otherwise. Override this method to create a non-synchronizing,
stateful component (return false), or a synchronizing stateless
component (return true).
If this is confirmed, I can file a documentation bug @ radar.
Please do.
