Hi,
I'm making a new module for setting a list of dates using the Cuyahoga.ServerControls.Calendar control. I'm making it based on the Downloads module. Now I'm at a point in which it gives me this error message when I try to save a date:
Could not commit transaction, one (or more) of the resources failed
Any help would be appreciated. Thanks in advance.

This could be many things. To find out more one must step through the action in debug to see what is happening.

Here's the stack trace

I can only say check your NHibernate mappings. Without the module to debug I can only say that something is causing the transaction to fail.
Check your mappings and how your object id's are generated.
Just Google each error and methodically check each possible avenue.

Ok, thanks !! I've found that I had written "unsaved-value=-1" instead of "unsaved-value=0" in the mappings file, and that exception came from there. The program is still giving an exception but now is a different one. I think I can solve it in a few minutes more.
Thanks a lot.
