Workflow error during architecture reconstruction process

[mingqing007]

What steps will reproduce the problem?
1.follow the instructions from the screencast on how to use Archimetrix: http://www.cloudscale-project.eu/results/screencasts/
2. during the step for architecture reconstruction (Archimetrix > Start Architecture Reconstruction) an error occurs, as can be seen in the attached screenshot.

What is the expected output? What do you see instead?
A successful architecture reconstruction process will result in additional folder with the model files. Instead, an error message is generated.

What version of the product are you using? On what operating system?
OS: Win 7, Developer Installation (Kepler)

Please provide any additional information below.
The Workflow failed error is similar to reported issue with user installation (https://code.google.com/p/archimetrix/issues/detail?id=8), but, as it can be seen from the console logs attached for both issues, the exceptions are different.

The abstract type of ModelImpl was not handled by Somox. I committed the changes in Somox and I tested the appointmentscheduling-api project.
You should get update of Somox plugins and test yourself. When there is still an exception, please open new issue.
