Replacing WTPart
If you want your site to use only custom part and not WTParts, use the following procedure.
To replace WTParts with custom parts:
1. Add custom part support to HTML Search.
2. In picker.properties, use the xconfmanager to change the type list entries that contain a type identifier for WTPart to the custom part type identifier you created in the previous step.
3. Restart the method server.
