Re: Is that a way to check or uncheck a checkbox using data binding?

[Sandro Martini <sa...@gmail.com>]

Hi all,
I'm ready to look better at this, maybe to include in 2.0.3 (soon to
be released) ...

Objections from someone for including this ?
If not I'll create a jira issue (and post here the link) , but I need
the original author to attach there the code, so we are all happy (due
to ASF rules) :-) ... ok ?

Tell me.

Thanks,
Sandro
