Re: Tree2 and selectBooleanCheckbox status processing

[Andreas Niemeyer <an...@gutzmann.com>]

Hi,

I got it solved in a more common without iterating through the HTMLTree 
(this seems to be buggy since the node address information is null/ unset)

The checkbox status is saved, a mistake happened by using the 
clientSideToggle first.
The checkbox status is hold about the Hashmap reference in the backing bean.


Regards,
Andreas
