SQL Developer Data Modeler

Friends,

I am trying to import entities into into SQL Developer Data Modeler from Oracle Designer 10.1.2.3.

In case of need I perform these steps to perform the import:

File --> Import --> Oracle Designer Model --> Select database connection --> Select work area --> select application system --> select one entity --> Click finish --> Import starts


During the import process I see an alert dialog box with the message:

There are errors in import - check Log file 

Clicking Ok dismisses the alert box and I see the following summary screen:

Oracle SQL Developer Data Modeler Version: 2.0.0 Build: 584
Oracle SQL Developer Data Modeler Import Log
Date and Time: 2010-08-09 14:27:26
Design Name: erdtest
RDBMS: Oracle Database 10g

		All Statements: 		32
		Imported Statements: 	32
		Failed Statements: 		0
		Not Recognized Statements: 	0

The Entity is then displayed in the Logical View within SQL Developer Data Modeler.

Upon checking the log file I see the following entry:

2010-08-09 13:50:34,025 [Thread-11] ERROR ODExtractionHandler - Error during import from Designer Repository 

java.lang.NullPointerException

	at oracle.dbtools.crest.imports.oracledesigner.ODExtractionController$Runner.run(Unknown Source)

Can anyone shed any light on this error?

Thanks in advance for any help you may be able to provide.
