Supporting WTPart and Custom Part
To have your site use both WTParts and custom parts:
1. Add custom part support to HTML Search.
2. In picker.properties, use the xconfmanager to add the custom part type identifier that you created in step 1 to those type list entries that contain a type identifier for WTPart.
3. To add an All type list entry for a type list, add an entry with the ALL type identifier used by the configured search attribute list.
4. Restart the Method server.
