Issue with BPMN2.0 Editor

[bhaskarven]

I was trying to run some tutorial by creating the process model in BPMN2.0 editor. I am facing the following issues :

1. I tried modifying an existing bpmn file according to my requirement. The moment I saved the changes there is a pop-up

    saying "The user operation is waiting for building workspace". Then when I run the program I get a bunch of schema errors

    which I have reproduced below. I am not able to make even a minor change such as moving a node or editing a property

    of a node. I tried creating a new BPMN diagram and that is also does not work. But I am able to compile and run demo

    programs.

Hello World

2. The properties panel for the script task is somewhat different from what it is in the tutorial. The Action property is missing and hence I cannot

    open the "Action Editor" for writing custom java code or importing Jar files. Also some other properties such as "variables" are missing in the

    process properties panel.

    I installed the graphiti & BPMN editor plug-in as described in the User Guide. The only change being the one shown below due to

    compatibility issues.

    As per User Guide => Graphiti 0.7.1 and Codehoop (BPMN) => 2.0

    My installation       => Graphiti 0.8.0 and Codehoop (BPMN) => 2.0

Please find attached snapshots of the script node properties panel and the process properties panel

The schema errors have gone after I did a clean installation of eclipse and the associated packages.

But I still have the problem mentioned in Point 2) above. Some of the task properties do not show up.

For example the uset task properties do not show "Parameter mapping" and "Result Mapping" I am also

not able to look/modify process properties. Please find attached user task properties panel.

Configuration => JBPM5.2, JBOSS App Server 7, BPMN Editor 2.0, Eclipse Indigo SR2

Any hints on what needs to be done is most welcome.
