Same issue with markLogicDatasetGraph.deleteAny(node, null, null, null);

kkanthet commented 9 years ago

Same nullpointer with findNG when subject is null

markLogicDatasetGraph.findNG(NodeFactory.createURI("http://originalGraph1"), Node.ANY, NodeFactory.createURI("http://www.w3.org/1999/02/22-rdf-syntax-ns#type1"), null);

I think I'm good with a fix for this.

kkanthet commented 9 years ago

Verified that nullPointer is not longer thrown and Find and Delete are working as expected when passed in null
