NOTE: As per JCR-2558, the following code snippets use a slash at the end of the absolute path.

DescendantNode constraint factory method doesn't work:

qomFactory.descendantNode("mySelector","/documents/My Folder/" );

However the following node retrieval works just fine:

session.getNode("mySelector","/documents/My Folder/");
