In the wiki page for custom presentation development, the sample Star application uses a method call in addListeners() that is not found with the 3.0.1.1 sdk classes..

<code> 
private void addListeners() {
   PresentationHandlerManager mgr= (PresentationHandlerManager) getSite().getAdapter(PresentationHandlerManager.class);
   if (mgr != null) {
      mgr.addPresentationUpdater(fPresentationUpdater, getDescriptor());
   }
}</code>
anyone know what this should be replaced with?
it appears in some of the other code to be
getPresentation();

Resolution:

when I built the projects, both mine and the sample, I have V4 SDK selected as the plugin target platform.

and altho I changed it, it did not actually change. (even tho the code compiled ok).

when I changed it from 3.0.1.1 to 3.0.1, then suddenly everything reset.
now the sample works and my code does not crash..

anybody?  trying to run the samples on 3.0.1.1, it doesn't compile
and changing to what appears to be the same code in the official object type parts
yields a 'no such function' exception.. yes, duh,  its looking in the wrong class tree

com/ibm/team/workitem/common/internal/  - not here
instead of
com/ibm/team/workitem/ide/ui/internal/presentations -- its here

but I get an exception
java.lang.NoSuchMethodError: com.ca.extensions.DeliverableFromWorkitem.getPresentation()Lcom/ibm/team/workitem/common/internal/presentations/PresentationDescriptor;
on that call.

I find it interesting that this class is com/ibm/team/workitem/common/internal/
is not the same one where this method is defined.
com/ibm/team/workitem/ide/ui/internal/presentations

I restarted the test eclipse clean, but still see this same error
