This is my thought too, but then i have no attribute for it. But I need this if i want to build a generic query mechanism, for instance in cases i don't know the exact class and it's methods. For example a user should be able to define it's own Bookmark defintions for building Word Documents based on the data in the database. He can do this by defining a path to the data based on the Metadata of the model.
I'd use the Criteria API to create dynamic queries based on what the user wants to see.

One part of it is to manage all tasks an employee has to do per day. This could result in between 50 to 100 task records for every employee per day. So it ended up with at least 30000 records per year. So far so good. But if my Employee class has a one- to-many relation to the Task class, NH would load all Task records for a concrete Employee. But this is n't really necessary. The user decides which tasks he wants to see, given for example a specify date range. I surely could apply a filter with "from" - "to" parameters, but then i have to enable it with the session. On the other hand, the filter should be dynamic, so i dont know, wich conditions a user will apply( fromDate only?, fromDate an toDate?, fromDate and fromTime? etc.). Is there a way to manage this in an elegant way or should i implement this without the relation mapping?
