Description Jan Rosczak

Lets say I have the following simple model:

AttributeTable
String name

GreenAttibuteTable extends AttributeTable

BlueAttributeTable extends AttributeTable

In my repository, I have four instances of GreenAttributeTables and three instances of BlueAttributeTables.

Using the OCL query string "AttributeTable.allInstances()" to get all instances of AttributeTables, GreenAttributeTables and BlueAttributeTables does not return any result, but I would have expected to get back seven instances of AttributeTables (the green and blue ones together).

As Bug 329389 indicates, it should generally work.

See Bug 400907 for the analysis of this problem. 

(Perhaps better to reverse the duplication direction.)

I've fixed this both for eager and lazy extents:
commit f2af641004b144f4e0330e20ed9a5abeaeda15b0

Please note that I've set the default to lazy extents. This can be overridden via OCLQueryHandler.createsLazyExtents() or the (new) boolean query parameter "cdoLazyExtents". I've also added OCLQueryTest.Lazy to verify both extent creators.
