Another feature of Momentics:
If you have an App icon whose file name is not icon.png then momentics is incapble of supporting that different file name properly.
Whilst you can 'Remove' icon.png in the Icon: section of the Application pane of the BarDescriptor Editor and then add 'NotCalledIcon.png' as your icon, the Blackberry Application Descriptor editor fails to update the actual xml correctly.
Basically you have to manually remove the line that remains in the bar file that says
<asset path="icon.png">icon.png</asset>
for the ide to be able to build your app - else it moans that icon.png does not exist
