EntityQuery with empty restriction

05. May 2008, 16:13 CET | Link jan novak

I have exactly the same problem like in topic mentoined bellow:

http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029206#4029206

There is a list of objects which serves as restrictions for search condition.

If this list isn't empty, it works well.

But when the list is empty, this exception is thrown:

restrictions.add("action.region in (#{actionFilter.regions})");

Caused by: org.hibernate.hql.ast.QuerySyntaxException: unexpected end of subtree [select action from cz.Action action where action.region in ()]
        at org.hibernate.hql.ast.QuerySyntaxException.convert(QuerySyntaxException.java:31)

        at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:64)
        ... 200 more

It doesn't seem to me like a database error as it is mentoined in the link above.

thanks for clarification
