Sylwester Szykula the test case link you provided points to the main branch of our test case templates repository. Please provide a project that reproduces the issue you’re encountering so we can look into it.

By the way, from a quick look at your forum post, it looks to me like you could just select the root object itself instead of selecting each of its properties and expecting a Pet typed result (which in turns involves dynamic instantiation of you entity class). Something like cq.select(root) should do the trick.
