YuYu,

You haven't given us enough information to help you. Please read:

http://faq.javaranch.com/view?HowToAskQuestionsOnJavaRanch

particularly the link TellTheDetails, and see if you can give us the details we need to help you.

Items of interest would be:

Where is this error occurring? When the framework initializes? When you're validating a specific form?

If it's happening with a particular form, show us the xml you've written that defines the validatoin for that form.

Have you done anything to try and solve this? (e.g. remove validations one by one to see which one is failing)
