Re: [CForms] Binding error while saving back?
Hi Tim: Thanks for the tips, we found the main object was not properly constructed. It throws the exception. We happily solved the problem. :-D Best Regards, Antonio Gallardo Tim Larson dijo: > On Sat, Jan 31, 2004 at 06:41:49PM -0600, Antonio Gallardo wrote: >> Hi again :-D >> >> In another place we have a binding problem: >> >> >> >> >> >> >> Interesting is that this binding works while load the form, but file >> while >> saving the values in the Java Bean using the binding framework.

Also, is this snippet inside some other context, such as a repeater, that could be where the binding code actually messes up? I have found using a javascript binding acts as a good substitute for "println" statements when debugging issues like this. You could use a javascript binding right before the context binding or before the value bindings to print out the values of the jxpathcontext and jxpathpointer to see of they give any clues. --Tim Larson
