Hi,

My project is based on EMF . It make use of EMF.Edit command
framework.

As the model file is too large, I want to use Teneo to promote the
performance,for example , paging the records , sort records in db, etc.

By customed loadUsingDefinedQueries() method, paging function is
implemented.

But in my Interceptor's onLoad() output, I found out that each time
the RemoveCommand is being created, all records will be loaded.

After I use my customed PersistableEList to override contains
()/containsAll()/listIterator(), the extra load disappear.

But some delegate***() still load records from db...

In fact, all the content appear in UI has been in resource , but the
object's persistableEList's delegate don't know.


Has anyone solved this kind of issue?

Any idea would be appriciated.


Anthony
