How can I dynamically control display of menu items in Windchill?

Hello,

I am developing a custom application for Windchill 10.

My code is started by clicking a custom menu item that is defined using the custom-actions.xml file.

The menu item belongs to the context menu for objects of type EPMDocument.

Now, I need to show this menu item only for assemblies (docType = CADASSEMBLY), but not for

other types of EPM documents (i. e. drawings, CAD parts, etc.).

I found out that it was possible to define an "includeFilter" (a special Java class) that can be used

to dynamically show or hide a menu item.

My testing filter class looks as follows:

import com.ptc.cat.ui.client.action.ActionFilter;

 

public class MyActionFilter implements ActionFilter {

 

     @Override

    public boolean test(List<StructureModel> structureModels, View view) {

        // Decide whether the menu item shall be displayed and return true or false.

        return false;

    }

}

The filter must be registered as a Windchill service, so that it can be called.

My problem is, that I do not know how to register it. My filter never gets called.

Has anyone got any experience in this area?

Thanks in advance
