Oracle ADF Cache issue

Question

Hi,
I've got a question about the Entity/View Object caches.
I wrote a web service in the ADF.
I implemented a simple custom method called "fun" in the AppModuleImpl.java.
The implementation is as follows:
public int fun() {
return getOdczytVO1().getRowCount();
where OdczytVO is a View Object based on an Entity Object called OdczytEO.
While executing this method via web service I noticed that server executes View Object's query all the time.
The method returns a valid number of rows, so the Entity Objects were cached.
When I executed this metod again, server executed the View Object's query again.
So my question is: does the ADF cache the Entity/View Objects and if so why it doesn't use them in this case.
Is there any online information about how the ADF caches works and how to use them?
Best regards & thanks

can you try to use getEstimatedRowCount() instead of getRowCount().
