[SOLVED] HQL unexpected AST node: {vector}

HQL unexpected AST node: {vector}

I'm trying to write an HQL query to grab a list of users that belong to a particular organisation, or any franchisee from a list of franchisees, however hibernate isn't able to parse it. I can't figure out why. Here is the HQL:

from User u where 
(u.parentOrganisation = :topLevelOrganisation or u.parentOrganisation in :franchisees) 
and u.parentOrganisation.deleted = false 
and u.active = true

This is the error that hibernate spits out:

unexpected AST node: {vector} [from com.myapp.User u where (u.parentOrganisation = :topLevelOrganisation or u.parentOrganisation in :franchisees0_, :franchisees
1_, :franchisees2_) and u.parentOrganisation.deleted = false and u.active = true]. Stacktrace follows:
Message: unexpected AST node: {vector} [from com.myapp.User u where (u.parentOrganisation = :topLevelOrganisation or u.parentOrganisation in :franchisees0_, :fr
anchisees1_, :franchisees2_) and u.parentOrganisation.deleted = false and u.active = true]

If I take out the or u.parentOrganisation in :franchisees bit, so my query looks like this:

from User u where 
(u.parentOrganisation = :topLevelOrganisation) 
and u.parentOrganisation.deleted = false 
and u.active = true

Then it works fine. What's wrong with my syntax? Why is hibernate complaining about that extra clause?

Solution

Oh, it turns out that I needed to enclose :franchisees in parentheses:

from User u where 
(u.parentOrganisation = :topLevelOrganisation or u.parentOrganisation in (:franchisees)) 
and u.parentOrganisation.deleted = false 
and u.active = true
