I tried to create new abstract wsdl and got the next NPE: java.lang.NullPointerException at org.netbeans.modules.xml.xdm.XDMModel.flushDocument(XDMModel.java:880) at

It is reproducable for concrete WSDL too. Steps to reproduce: - Invoke new WSDL File Dialog (step Name and Location) - press next (step Abstract Configuration) - press back e.g. to perform some changes in the first step information (step Name and Location) - press next (step Abstract Configuration) NPE is appeared
