java.lang.NullPointerException while reimporting model

[former_member182374]

Hi All,

I have a Web Dynpro project that contains several models.

When I try to add a new RFC (by reimporting the model) I get java.lang.NullPointerException.

I can add the RFC to a new model without any problem but I need to add it to this specific model.

This is the full error:

Plugin Name: Web Dynpro Model Editor Services

Plugin ID: com.sap.ide.webdynpro.service.modeleditor

Class: com.sap.ide.metamodel.importers.rfcmodel.DynamicRFCModelImporter

Method: doImportDynRfcModel()

Message: The RFC could not be imported. Please rectify the error and then try importing the model.

Exception: com.sap.ide.metamodel.importers.rfcmodel.RFCImportFailedException: RFC Import failed. Cause: class java.lang.NullPointerException:null

I tried to restart the NWDS or test it on another computer - didn't help.

My NWDS version is SP16.

Thanks,

Hi,

Check whether this helps.

Solved it on my own.

My model contained several RFC's.

One of them was moved to other backend system (from R3 to BW).

I got the error because of the missing model and not because of the new model I wanted to add (although, from the exception's details it isn't very clear )-: )
