How to decrypt this (Seam's exception) error message?
Hello,
I am new in writing JSF. I have no doubt that my pages are full of bugs. How do I go about debugging the pages to figure out what error Seam is referring to?
For example, Seam threw the following exception in the log:
12:04:44,734 ERROR [STDERR] May 10, 2007 12:04:44 PM com.sun.facelets.FaceletViewHandler handleRenderException

That's the end of the log. How would I decrypt this error message?
Thanks for your help.
