You can do this with a ContextualView, assume it is
WPSPortContextualView. You also need a factory for making the contextual
view - WPSPortContextualViewFactory.
In the WPSPortContextualViewFactory you say:
public class WPSPortContextualViewFactory implements
ContextualViewFactory<Object> {
public boolean canHandle(Object selection) {
if (!(selection instanceof ActivityInputPort) &&
!(selection instanceof ActivityOutputPort)) {
return false;
}
return (hasContainingWPSActivity(selection));
}
public static boolean hasContainingWPSActivity(Object selection) {
Processor p = null;
Dataflow d = FileManager.getInstance().getCurrentDataflow();
if (selection instanceof ActivityInputPort) {
p = Tools.getFirstProcessorWithActivityInputPort(d,
(ActivityInputPort) selection);
}
if (selection instanceof ActivityOutputPort) {
p = Tools.getFirstProcessorWithActivityOutputPort(d,
(ActivityOutputPort) selection);
}
Activity a = p.getActivityList().get(0);
return a instanceof WPSActivity;
}
public List<ContextualView> getViews(Object selection) {
return Arrays.<ContextualView>asList(new
WPSPortContextualView(selection));
}
}
You need to list WPSPortContextualViewFactory as implementing the SPI of
ContextualViewFactory. So the file
net.sf.taverna.t2.workbench.ui.views.contextualviews.activity.ContextualViewFactory
in your src/main/resources/META-INF/services needs to have the fully
qualified name of WPSPortContextualViewFactory

I am sorry but I do not understand this part of your question.
