Querybuilder with EMLDatasource actor does not return data
See attached workflow for example.
When querybuilder interface is used to limit the columns/records nothing is returned.
When the actor is first dragged to the canvas (w/o specifying filters) data is returned.

This problem wasn't caused by multiple tables or single table. Actually there is a space in attribute name cause the problem - illegal db attribute name (with a space between two word). I added a new method to transfer space to underscore. It fixed the problem. The attached workflow now works.
