Java NullpointerException when getting the representation

Hi,

I get an error (java.lang.NullPointerException) when executing the following lines at :

Representation rep = RepresentationHelper.Service.getDefaultRepresentation(CurrEPM)

This is the code :

When I request info from the EPMDocument (CurrEPM) like this :

TracePath = TracePath + "\n" + "+2.2 " + "Number: " + CurrEPM.getNumber() + " Name: " + CurrEPM.getName() + " Status: " + CurrEPM.getLifeCycleState.toString() + " Version: " + CurrEPM.getVersionIdentifier().getValue() + " Iteration: " + CurrEPM.getIterationIdentifier().getValue();

I get :

+2.2 Number: M000056923.DRW Name: FOLDER PLATE Status: DESIGN Version: B Iteration: 1
