However, if there is always 1 and only 1 instance of your data subfeature you might as well add those properties directly to the main feature for simplicity. </p> <p>If you want to edit your data subfeature you will need to define placement and edit methods. Look at the MyAppSettings class in geoexample, especially the Methods section for that class. Also look at the code inside example.mvba that gets called.</p> <p>Hope this helps,</p> <p> &nbsp; &nbsp;Martin</p><div style="clear:both;"></div>
