The activiti modeler setuped according to http://code.google.com/p/signavio-core-components/wiki/InstallationInstructions and the UTF8 is ok.
OS windows7
Tomcat 6.0.36
Firefox 16.0.1 / Chrome 22.0.1229.94

Steps to reproduce:
The modeler starts-up.
Choose New -> Business Process Diagram (BPMN 2.0)
New tab appears with a never ending running progress for creating new diagram and new diagram is not created

Tomcat logs:

The same occures both on Windows and on Linux.

Has anybody faced such an issue and how to solve it?
