It does look like a variable in your Velocity is null..  While JIRA is trying to render the view (PortletImpl.getViewHtml), it is encountering a variable which is null.

That's as much as I can deduce from the stacktrace.. Hope that helps..

Cheers,
Tim

Thanks a lot sir,

But Velocity is not null... when the plugin is alone in lib folder it works well but when i add the other plugin one of them stops working and giving this error but the velocity files or not null for both of the plugins but maybe one velocity deletes other one when i put the both plugins together because they are the same plugins which connects to different databases im sure im missing to do sth about the velocity files maybe i need to locate them somewhere else maybe i need to change their names... i have tried but couldnt get the result that i want to have

Anyway thanks a lot for your reply...

Regards.

It sounds like you have two plugins with the same identifier.  I am guessing that you have copied the a .jar to a new .jar name in the WEB-INF/lib folder?

This simply will not work - one plugin is being loaded and the other one will *always* be ignored as the configuration and code all need a unique reference to it.  You can re-use the same code and .vm files in a copied plugin, but you must give each one a unique name.

Thanks Nic

what do u mean by "identifier"? Both of the plugins have different names in web-inf/lib and i didnt copied the .jar file... they both have different class names and descriptions in atlassian-plugin.xml if you mean it.

Regards

Sorry, I was using a generic term (identifier)

In Atlassian-plugin.xml, look for the identifier called "Key".  For example <atlassian-plugin key="com.cobaltservices.jira.plugin.customfield.categoryfields" name="JIRA Category on issue plugin">
