Hi -
I have a HiddenSelectQuestion component that contains a set of hidden
elements. I want a javascript function that sets the value of the named
element. I have debugged this as straight HTML to make sure the Javascript is
valid. However, Tapestry gives a parse error.
The script is at the bottom of the email. The Tapestry parser does not seem
to like the '<' in the while statement and gives the following exception...
net.sf.tapestry.ApplicationRuntimeException
Unable to parse script
/com/informative/study/jwc/HiddenSelectQuestion.script.
net.sf.tapestry.util.xml.DocumentParseException
Unable to parse /com/informative/study/jwc/HiddenSelectQuestion.script:

or markup.

I am using Tapestry 2.2 in JBoss 3.2 Beta 2. Any pointers or suggestions
would be greatly appreciated! Thanks...
Dorothy
