Brad Maxwell updated JBIDE-5394:
--------------------------------

    Attachment: InvokeHelloWSBPEL.zip


Here is my test project, I deleted the Mapping in the AssignInput2HelloWSRequest, so you can do the following to see the issue.
1) Select AssignInput2HelloWSRequest
2) Look in the Properties View
3) Select the Details tab in the Properties View
4) There should be no mappings
5) Click New
6) Create a Variable to Variable mapping
7) On the From side, expand the variable input / payload / input and select "input : string"
8) On the To side, expand HelloWSPartnerRequest variable down and select "name: string"
9) Click in the mappings area and it will prompt "Variable HelloWSPartnerRequest doesn't have initializer. Should it be generated?"  
10) Click Yes
11) Switch to the Source view of the Process
12) Search for this text: 
<bpel:literal xml:space="preserve"><tns:hello xmlns:tns="http://jboss.com/examples/ws/Hello" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</tns:hello>
</bpel:literal>
13) This text is what the variable HelloWSPartnerRequest gets initialized to.  When this process is deployed in Riftsaw and run it results an the error mentioned before.  The error is that XPATH cannot find "name" in the HelloWSPartnerRequest to copy to.  I found that adding <name xmlns=""/> above the </tns:hello> resolves the issue.  So it seems the HelloWSPartnerRequest is not getting completely initialized.
14) Also I noticed that in the AssignHelloWSResponse2Output step, where I copy from the HelloWSPartnerResponse / helloResponse / return to output / payload / result, that output seems to get initialized correctly.  Notice in the string below, the initializer created has <tns:result></tns:result>

bpel:literal xml:space="preserve"><tns:InvokeHelloWSProcessResponse xmlns:tns="http://jboss.com/bpel/InvokeHelloWS" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <tns:result></tns:result>
</tns:InvokeHelloWSProcessResponse>
</bpel:literal>

Thanks,

Brad

> After days of trying various things, I then began comparing my example to the quick starts.  I found the issue is 'name' is not being initialized.  I hacked the code and added <name xmlns=""/> and it resolved the issue.
