I have and entity lets call it Entity, and a Child collection Children.
I have a screen where the user has the Entity information, and a list with the Children collection, but that collection can be get very big, so i was thinking about using paging: get the first 20 elements, and lazy load the next only if the user explicitly presses the next button.
So i created in the Entity Repository a function with this signature:
IEnumerable<Child> GetChildren(Entity entity, int actualPage, int numberOfRecordsPerPage)
I need to use the setfirstresult and setmaxresult, not in the Agregate root Entity, but in the child collection. But when i use those two configurations, they allways refer to the entity type of the HQL/Criteria query.
Other alternative would be to create a HQL/Criteria query for the Child type, set the max and first result, then filter the ones who are in the Entity Children collection (by using subquery).
But i wasn't able to do this filter. If it was a bidirectional association (Child refering the parent Entity) it would be easier.
Any suggestions?
Any
