Hi Bob,
Most likelly either you have not specified SelectionSearchServiceImpl
in your module xml file correctly (so the URL doesn't match and it
can't find it), or there is something wrong with your own code that's
throwing an exception.
if 1) In the main dev shell window, you should see some exception
entries and one of them should say it can't find
SelectionSearchServiceImpl - what does it say?
if 2) you should be getting to here
public void onFailure(Throwable caught) {
setMessage("Selection search failed. ");
}
what is caught.getMessage()?
