Export a Workflow (.NWF) with a custom InfoPath Form (.xsn) included

Hi,

When I export a Nintex Worfklow (2010) with a "Collect Data" action and a Custom InfoPath Forms, the custom form is not included in .NWF export file.

I need to find a way to be able to publish an exported programatically workflow ( PublishFromNWF )

I tried the webservice and  PublishFromNWF method.

=> It works perfectly when there are no custom infopath form in original wrokflow.

=> It doesn't work anymore when a custom infopath form is included in original workflow  (Error : Server was unable to process request. ---> The system cannot find the file specified. (Exception from HRESULT: 0x80070002)

Please help ....

Etienne.
