I was able to import/export my data using session.exportSystemView() and
workspace.importXML() and it was looking pretty good until I attempted to
add a new node. When I go to add a new node, we checkin the node itself and
when it attempts to checkin the parent node, that is when I get a NPE. This
is the line which throws the NPE in AbstractVersionManager String
versionName = best.getName().getLocalName(); It looks like if no version
was available best would not be set. So when I check the parent node which
is failing, parentNode.getBaseBersion().getPredecessors().length returns 0.
I am wonder after I run importXML, do I need to do something to initialize
the versions?
