Web ui issues in RTC 3.0.1

Hi,

We had been using RTC 2.0.0.2 and had developed some of our custom web ui components. For example adding a button on the workitem editor, click of which would invoke a rest service . Following is the plugin.xml snippet of the web component showing the dependencies:

<extension>
<prerequisites>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
<requiredWebBundle>
</prerequisites>
</extension>

How ever when Iam trying to upgrade the same code base to RTC3.0.1, I can see the button's been rendered on the UI, but on its click , see this error in all the web ui components on run time:"com.ibm.team.process.web.projectArea is undefined". Need help to resolve this issue?

Regards,
Meghana
