Unable to create Model from DOE Data Object

[Former Member]

Hi,

I created a Mobile Laptop WebDynpro DC in NWDS 7.1, the build and deploy work fine.

The problem is that when I attempt to create a Model based on a Data Object from the

Mobile Middleware 7.1 DOE, I always get an exception when the Data Object metadata is

imported (the last step of the Model Creation Wizard).

Here's the exception :

Status ERROR
Plugin : com.sap.ide.cmi.core
code=0
Internal error
   Plugin name: Common Model Tools Core
   Internal error  : com.sap.ide.cmi.core

at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:113)

I know this is not related to Middleware authorization, I tested with a userid with full DOE authorization.

When I display the Data Object metadata from the Middleware, it shows as status 'active'.

The exception seems to complain about the backend key, but there is a backend key field in

the Data Object.

I have the same exception even with any SAP delivered Data Objects (MAM30_001, etc..).

any thoughts on what the problem is ?

thanks,

Yanick.

Hi Yannick,

This type of error can occur with local non-dc Mobile App when some jars required for the model generation are missing.

The easiest way to fix this is to create a DC for your Mobile app from the

Mobile App Offline perspective.

Let me know if it works

I created a new workspace in NWDS and then I created a new Mobile Laptop DC as you recommended.

Now the Model Data Object creation Wizard succeeds !! I get the metadata and the type definitions.

thanks!
