I was wondering if anyone has come across and problem using light streamer in GWT when also inheriting the GWTQuery package? Simply inheriting the gwtQuery package has the end effect of causing a subscription to become null. Remove the gwtQuery inherits and the problem goes away.

Excerpts from <project>.gwt.xml

<add-linker name="xs" />

<inherits name='com.google.gwt.query.Query'/>

JS client error with gwtQuery inherited.
