Hi Alessio, So in this case the suggestion would then be to modify the list (via annotation) as to teh type of object inside of it. This could be done with something like this:
@model type="org.geotools.geometry.GeneralEnvelope" EList getSpatialSubset() So the deal is that there is actually no EMF model generated for GML. The reason being that geotools already has objects which represent many of the entities in gml like Feature, FeatureCollection, Envelope, etc... So the strategy used for emf models which referenced GML (like WFS) was to just re-instrument the model in cases where GML elements and types are referenced. Does that make sense? We could go ahead and generate a EMF model for GML... It might save time in things like this. However for WFS it does not make sense since the reference was feature... and anything coming out of EMF would have to be adapted. For things like envelopes it might make more sense since its a much simpler data structure. Alessio Fabiani wrote: > Hi Justin, > > sorry to bother you again ...
