Error: method: createModel -> Failed to create model

[Former Member]

Hello Experts,

While importing an RFC(developer created - Z) with 'Adaptive RFC Model 2' in NWDS 7.3 SP04 i constantly getting this error;

method: createModel -> Failed to create model      [Error: com.sap.cmi.modeltype.arfc2.wizard.ARFC2ModelCreationWizard  Thread[ModalContext,6,main]]

java.lang.NullPointerException

	at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121)

When i import the RFC with the 'Adaptive RFC Model - DEPRECATED' one everthing works fine NWDS can get the RFC models. But i need the use the new version of RFC Import and NWDS is not getting models right.

Does anyone have any information on this error ?

Regards,
