[udig-devel] objectProperty

[Jesse Eichar]

I suspect you have to include the plugin id of the property:

>            <property
>                  expectedValue="StationFeatureType"
>                  propertyId="plugin.id.isStationProperty">
>            </property>
>         </enablement>



replace plugin.id. with the id of your plugin...  Hopefully that will  
work

I know it is confusing but the plugin id is required essentially for  
insulating the property against similarily named properties defined in  
other plugins.
