Previous answer is incomplete. It looks like BPEL message and variable manipulation is implemented in not a namespace-controlled way. Then, the previous query is correct but namespace will be missing or mixing up. So you have to add the namespace in the query or the namespace will disappear In previous code, if the element "part1" in defined in a schema referenced in BPEL headers like xmlns:sch=.... a correct query looks like | | <assign> | <copy> | <from variable="LoginOperationRequestVar" part="inRequest" /> | <to variable="ControlloAccessoOperationRequestVar" part="part1" query="/part1/sch:nome" /> | </copy> | </assign> | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4098701#...
