[jboss-user] [JBoss jBPM] - BPEl Problem: Assign with Literal values

[agusgr]

Hello,
I'm working with the jbpm-bpel-1.1.Beta3 and with the BPEL plugin for eclipse.
I have develop several BPEL services but I have a problem with a portion of code.
When I try to deploy a proccess with this:
<bpws:assign name="Assign" validate="no">
  |             <bpws:copy>
  |               <bpws:from>
  |                 <bpws:literal>
  |                   <bpws:literal>'URL not found'</bpws:literal>
  |                 </bpws:literal>
  |               </bpws:from>
  |               <bpws:to>$output.response/tns:Country</bpws:to>
  |             </bpws:copy>
  |           </bpws:assign>
  | 
I have this:

If I remove the literal statement, it works well.
The question is:
Does the jbpm-bpel-1.1.Beta3 extension supports the literal assignments?
Is there any error in my code?
Thank you and sorry about the long post

Agus
