NWDS ABAP WD Chip integration list is empty

Hello Experts,

I am trying to integrate ABAP WD chip with nwds bpm human task.

When i try to import the chip in NWDS the chip list is empty (R/3 connection is already created).

I already created the Inport, and Outport,(1 inport, 2 outports success, error ) , made the component as Remote-Enabled Chip (WDR_CHIP_LAUNCHER )  according to the turorial below.

http://scn.sap.com/docs/DOC-25436

and the discussion http://scn.sap.com/thread/2088388

My chip is saved/Consistent.

I tried in NWDS with 'show supported components only' unchecked too.

No result.

I already checked the note 1442668. and the requirements are ok.

I am using NWDS 7.31 sp 11.

PO server 7.4.

SAP_basis 731

Any suggestions are welcome.

Thanks in advance.

Regards,

Antony.
