We are trying to use the dynamic proxy for some of our collections.
However, I am getting an error and am unable to tell exactly what the
problem is.
The invoke method of IndirectHandlerDefaultImpl is saying that it can
not invoke a particular method. However, in looking the stack trace, I
can not figure out why it is unable to invoke the getSubGroup method.
Can someone point me in the correct direction?
The relevant portion of our model: ClientRelationship has a collection
of NewClientGroups which have a collection of Subgroups. The error is
getting created when we are trying to retrieve one subgroup (by it's
unique Id) from the NewClientGroup with the getSubGroup(int id) method
call.
