EntityProxy efficiency

Hi everyone,

I have a question about EntityProxy vs. ValueProxy and efficiency issues. I need to load a list of SubProxy objects using RF for display in a listbox inside an editor for an encompassing SuperProxy type. No SubProxy instance is modified by the editor, but because RF does not support inheritance, I must use EntityProxy as SubProxy's super-type. This means unfortunately that on loading the list of SubProxy objects (using one efficient Hibernate call), RF launches one find operation for each objects (thus creating X more Hibernate calls) which is very inefficient. Is this desired behaviour and how do I optimise my loading code. Currently it takes several seconds to load a list of ca. 100 SubProxy objects. I have encountered this problem before and solved it by using ValueProxy objects which are not version-checked by the RF engine. Could someone please explain me why the RF engine does a separate version check for each EntityProxy that I just retrieved from the DB?

Thanks for sharing your knowledge

Jerome
