Hql "delete CoreVerticalObject where childTreeName=:childTreeName"
work well

but neither "delete CoreVerticalObject where parentObject=:parentObject"
nor "delete CoreVerticalObject where unique.parentObject=:parentObject"
can work.

and another question, if use "select" clause, you must use:
"select cvObject CoreVerticalObject as cvObject where cvObject.unique.parentObject=:parentObject"
why not is:
"select cvObject CoreVerticalObject as cvObject where cvObject.parentObject=:parentObject"
I think that later is easy to use and understand

Thanks in advance
