Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction
I want to pass two hidden fields; username and keyName
from a JSP via a SUBMIT button:
<% String username = request.getRemoteUser();%>
View Articles
and an action mapping:
How come the username is not passed to the
FindEditorData.java while the keyName is successfully
passed. In the browser, I got:
name=null; kn=journal_category; kv=null
The code of my FindEditorData is shown below:
public final class FindEditorData extends Bean
{
public Object execute() throws Exception
{
// Obtain username
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username );
String property = getKeyName();
if (( null==property ) || ( null==value ))
{
StringBuffer sb = new StringBuffer();
sb.append( "name=" );
sb.append( username );
sb.append( "; kn=" );
sb.append( property );
sb.append( "; kv=" );
sb.append( value );
throw new ParameterException(
sb.toString() );
}
ResultList list = new ResultListBase
(
Access.findByProperty( this,property,value
)
);
list.setLegend( property,value );
return new ProcessResultBase( list );
} // end execute
} // End FindEditorData

Are you using the or html:hidden attributes? I
didn't see it in your email.
If you do, the values will be available in the request.

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction
My code was shown in my original message. I used two
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:
<% String username = request.getRemoteUser();%>

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction
I did not mess up lowercase and uppercase of the
hidden field I want to pass from my JSP to the
scaffold.ProcessAction. If it had been the
lowercase/uppercase problem, I would have gotten a
message saying that the variable could not be
recognized.
I pass two hidden fields at the same time. One of
them is successfully passed with correct value. The
other is passed but its value shows a 'null' in the
scaffold.ProcessAction. What could go wrong? Let me
show my code again:
Two hidden fields: username and keyName are passed
from a JSP via a SUBMIT button:
<% String username = request.getRemoteUser();%>

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction
Hi Caroline,
have you checked the source of the HTML page in the browser to see what
the value of username is, client-side? I expect the value is being sent
to the browser as null.
If that is the case, it is because request.getRemoteUser() is returning
null and that would be because you don't have or are losing your login
session.
