Error: MESSAGE Could not create action delegate for id: [message #461945] Thu, 18 January 2007 09:54 Go to next message

Hi Everyone,

I am new to ActionSet, so I added an actionSet using the PDE, and I made use of the example given/generated by the wizard. However I get the follwing error:

It's quite likely that the NewBookRequestAction has a static field of a class that can't be found on at runtime, for example, you've added a Jar to the .classpath instead of the Manifest.mf's Bundle-ClassPath or Require-Bundle.

Hi Alex,

Thanks for your reply, I am not too sure about your answer.. However I spotted this problem only occure when my action implements ISelectionListener, and I really want to implement this interface so I can control the enabling and disabling of the action i.e.:

public void selectionChanged(IWorkbenchPart part, ISelection incoming) {
if (incoming instanceof IStructuredSelection) {
selection = (IStructuredSelection) incoming;
setEnabled(selection.size() == 1
&& selection.getFirstElement() instanceof HierarchyNode);
} else {
// Other selections, for example containing text or of other kinds.
setEnabled(false);
}
}

Is there any way to overcome this?

Hi Ali,

I guess your problem is that you have no default constructor (with no
parameters) in your action class.

Hi Ilya,

I do have a default constructor in my action class. However I still have this error.

... which is *publicly* available? (The implicit package visiblity is a
notorious candidate of such problems)
