Hi everyone:

I'm trying to implement a method that returns a criteria. The idea is that I get a full criteria (join of three tables) and later I want to compare firstly an attribute of the first class and later an attribute of the third class, so I do.



When I debug it, in the variable crit I can see that sec's parent class is First.class and the thi's parent class is also First class, but actually, thi's parent class is Second.class.

After that when I do



I get this error:



My question is: Is there any way to use Criteria in order to get that thi's parent class is Second.class??? I suppose that is the reason why I get that error.

Thank you very much in advance[/code]

You should simple be able to use:

to do what you want - createAlias() simply returns an instance of the original criteria for method chaining, so you need to explicitly navigate to the child criteria with createCriteria(Second.class)[/code]
