getRecordWSOL returns null if there is no record - right.
There is no record, if it is deleted and the deleteClause is evaluated.

There are, two levels in the Data-Provider, one building the tree on 
nothing else as uids - this checks if deleted records are included, 
pages are allowed etc. It's on "create" of the Provider*.

the function buildRepresentationNode is called whenever a node is 
requested for display - the uid is fetched, and the other informatione 
are queried - like title, type etc, and information about "how the node 
has to look" is build and returned.

At this very point, no checks have (and need to take place). If a 
already deleted node is queried at this point, it already has been 
checked that this one explicetly has to be displayed.

The function, just generating a complete view for an already existing 
Node is not meant to be to return NULL.

Therefore, the checks in getRecordWSOL have to be deactivated.
