Hey all,
I created a new file format based on XML. A single XML file can contain
several kinds of features (point, polygon, ...) so I created a IService
subclass that provides several IGeoResource subclasses as members. My
IService can resolve to a DataStore (MemoryDataStore).
My problems are the following :
1) When I choose "File > New > New Layer > Files", I select my XML file
and then press "Next", I get an empty list of IGeoResources (on the
screen). I can then press "Previous" and then "Next", my IGeoResources
appear ! I now can really add them to my current map.

2) If I only choose to import the same content in the local catalog, I
get them in the Catalog view. I cannot use the context menu on the
IService (right click) and choose "Add them to the current map". I only
can use this operation on each IGeoResource. I have the same problem
with drag and drop on the IService from Catalog view to Project Explorer
view.
In both cases, if my XML file only contains one kind of information
(only 1 IGeoResource), this works fine, the problem arises only when I
have several members in the same IService.
I investigated uDig code and I found that some tests are done to
automatically select the unique IGeoResource when there is only one
IGeoResource in a IService. But the code doesn't seem to work in other
cases.
Thanks for your help.
Vincent
