RE: [Tomahawk] [SOLVED] Urgent: DataTable Update model not working
You're right! I was just debugging into it and way of confused, how the
request parameters are populated back to the model, when this local value
flag is never set... Now, I figured out, how this is done, cause since I
provided the correct identifier for my form in the actionFor attribute of
my command button, everything is working fine now!
Regards,
CAK

You'll be more likely to get help if you post what the particulars of
your problem are rather than telling us how you think the JSF
framework works or should work :-)
