from a PropertyPage, i'm trying to execute a Command that opens another
Window/Dialog:
What i get is the following Exception:
org.eclipse.core.commands.ExecutionException: No activeWorkbenchWindow
found while executing org.eclipse.ui.help.aboutAction
What is wrong?
Help is greatly appreciated.
Cheers,
Simon

public void handleEvent(Event event) {
final IHandlerService handlerService = (IHandlerService) PlatformUI
.getWorkbench().getService(IHandlerService.class);
