Daniel,
You are right that the mapping settings do not include the Index value. You need to change them.
To do this, the underlying objects must be available in the system, so --
* Launch your application and activate the form that displays the objects.
* Now, open the NameMapping editor.
* Select your PropertyItem object in the tree on the left of the editor and click Edit on the editor's toolbar.
This will invoke the Edit Name Mapping Item dialog that lists object properties.
* Move the Index property from the right list in the dialog ("Available") to the left list ("Selected"), specify the index value to be used for object recognition and click OK to save the changes.
Now, you can map other ProjectItem objects. When mapping, you select the properties to be used for object recognition. Include the Index property into the mapping condition.
