Description of problem:
DataQueryDataCollectionAdapter.getObjectType() calls
getDataObject().getObjectType() to return the object type. This fails
if next() has not yet been called. One consequence of this is that you
cannot filter on permissions, as the permissions code calls
getObjectType() on the passed-in DataQuery

London 5.2 change 38321 changes this to:
(ObjectType) getType().getProperty(m_dataObjectProperty).getType();

so that filtering is possible.



Version-Release number of selected component (if applicable):
5.2 and later.

How reproducible:
always

Steps to Reproduce:
1. call getObjectType on a DataQueryDataCollectionAdapter before
calling next() on it.
