[rules-users] Problems importing sub-process with Designer 2.0

*Hi,

We saw Tihomir blog about jBPM Web Designer 2.0 released
(http://surdilovic.wordpress.com) where there is mentioned a list of new
features including: ''Support for sub-processes'. We went to the
documentation link but couldn't find anything about sub-process. We'd love
to hear more on this.

We have download and installed the jbpm 5.2, which comes with Designer 2.0,
but when we tried to upload from Eclipse to Guvnor a simple process that
makes reference to a simple sub-process, we are getting the following
exception:*

*Using "import from BPMN2", we also tried pasting the xml (bpmn2 content),
but we got again the former exception regarding to "Unresolved reference
'my.subprocess'". Forgot to tell, the sub-process with Id=my.subprocess was
loaded in Guvnor successfully before trying to upload/import the process
that makes reference to it.
Any help will be appreciated.*
