hasErrors question

Hi folks,

Thanks again for all your help – this list is an invaluable resource!

My question is about hasErrors…  I can see in the generated controller where it will call hasErrors() on an object.  How do I set errors like that?  I tried obj.hasErrors = true, but that didn’t work.  I don’t know what to search for, so I can’t find any documentation besides what the tag hasErrors does…

Thanks,

Pam
