Re: Please Help! Unable to Pass A Hidden Field To
scaffold.ProcessAction
Are you using the <input type="hidden" ....> or html:hidden attributes? I
didn't see it in your email.
If you do, the values will be available in the request.

Richard

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction
Posted by Caroline Jen <ji...@yahoo.com>.
My code was shown in my original message. I used two
<html:hidden ... > tags to pass two hidden fields, one
is successfully passed while the other shows null. By
the way, I do not use 'request' to retrieve the value
of the hidden field because my Java class is a
scaffold.ProcessAction type. I simply use getXxx.
Let me show my code again:
<req:isUserInRole role="editor">
<html:form action="/find/Category">
<% String username = request.getRemoteUser();%>
<html:hidden property="keyName"
value="journal_category"/>
<html:hidden property="username"
value="<%=username%>"/>
<html:submit>View Articles</html:submit>
</html:form>
</req:isUserInRole>
