around. In my Unit test file I changed it to:
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
xmlns:sdm="sdm.*"
xmlns:services="services.*">
<services:Services id="myServices"/> <---changed
<sdm:SiteDataMaint/> <---changed
</mx:Application>
Basically just swapping the order of the services and sdm tag made it
work.
Thanks for all your efforts Doug!
