Using designer 8, I deploy the state service example models (found here) to an 8.2 beta1 teiid server. The models deploy successfully and the teiid connection in designer displays the catalog and stateService/stateServiceView schemas.

However, running the following query

exec stateServiceView.getAllStateInfo();

results in a generic TeiidException in designer's status view.

This exception comes from a NullPointerException that is displayed in the jboss server log.

The NPE has been fixed on the server side, but the Designer metadata for the ws procedures (invoke/invokeHttp) should be updated to include the optional streaming parameter. See also https://issues.jboss.org/browse/TEIID-2148 which introduced the initial regression on the Teiid side.
