[platform-help-dev] help server cannot resolve plugin-id

[Robert Krüger <krueger@xxxxxxxxxx>]

Hi,

I'm trying to use the help server to start a web application from within 
one of my plugins using the following code (which is called from an action)

WebappManager.start(
            WEBAPP_NAME,
            descriptor.getUniqueIdentifier(),
            new Path("web/deployment"));

where "descriptor" is the instance of IPluginDescriptor which is handed 
to my plugin during initialization and the ID returned is correct as 
well. However, I get a CoreException with the message

"Location of plug-in <my-correct-plug-in-id> cannot be resolved".

The ID is correct and the Plug-in was obviously initialized as the code 
is called from an action my plugin contributes. What makes it even 
stranger is that this code works fine, when I run it in the PDE. The web 
application starts and serves requests under the correct location. This 
leads me to believe that the message in the CoreException thrown by the 
WebappManager is misleading as it seems to be something else.

btw this behaviour has been the same from 3.0M4 - M6 (I'm not sure about 
earlier versions).

I would be grateful for any hints.

Regards,

Robert
