This does not appear to be a general problem with QueryBuilder since it does work when a single EML2 datasource is dragged to the screen. (Dan Higgins)

I need to amend previous comment. QueryBuilder seems to work when there is a SINGLE table associated with the dataset!

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.
