A SelectComposer's @VariableResolver is not used to @WireVariables when using the ZK JSP toolkit.
The included ZK Maven project provides a simple example.

Two ZK pages are included, one.zul and two.jsp
In both, MyComposer is applied to the only ZK component. In the former, MyVariableResolver is correctly called to resolve the Object 'wireMePlease'. In the latter, however, MyVariableResolver is never called.
