Subject Re: Selectable DataTable or similar to that
Date Wed, 08 Nov 2006 00:24:10 GMT
Hi,

since no values are displayed at all, possibly valuechange-method is
not called.  I have put the binding - thanks.  How can I check if the
method is called?  Sorry, this is my very first JSF application.

Thanks once again.

With regards,

Damar
