Hi Isomorphic,

does this stack trace (using latest 11.1p) make sense to you?

It was thrown in a DMI for request.addToCriteria(), where resellerSet is a HashSet<Long> filled with some entries.

public DSResponse fetchDirectionDown(DSRequest request, HttpServletRequest servletRequest) throws Exception {
.....
request.addToCriteria("ID", DefaultOperators.InSet, resellerSet);
return request.execute();
}

Best regards

Could you please provide DMI code that builds criteria and/or (if) criteria that comes from the client to show us the complete criteria at the point you are making this call, causing an NPE. Thank you.
