The second operand isn't a valid Java expression.

Rather than being forced to use "from", consider inserting SubObjects as facts.

   $subobj: SubObject(string="TST",int=1)
   obj:Object(collection contains $subobj)

Yes I know that from can be used with DSL. I was just trying to think of a
way to do something with a sub part of the object(i.e a dsl entry with a - )

I guess I could also have a method on my main object that takes parameters
and just do a not null check...
