[jboss-user] [JBoss jBPM] - Re: How can I assign attribute of the complex object?

[pkovgan]

Ok ,
I'll try to give concrete example:

I failed on last assign in BPEL description below.
Actually I did not fail(no errors), but I do know that last invoke was not completed. Probably because last assign is wrong.

My process should connect to WS called Customer and retrieve Complex object as response:

My bpel is:

As you noticed last assign takes variable _var2 from call to WS,
WSDL of this WS below:

Could you help me?
What's wrong in my variable/part/query?What is wrong in WSDL?

Please, help.

Thanks in advance.
