| Strange behavior of ProjectExplorer for .ecore files [message #424101] |

Hello
When I use the ProjectExplorer to open a .ecore file in Eclipse 3.4 I
get a view where the toplevel package is presented more than one time.
In fact it seems as if the number of times it is shown corresponds to
the number of elements contained in the toplevel package.
Examplified, a model like this:
model
-element1
-element2
is shown as:
model.ecore
-model
-model
In the project explorer. I guess this is related to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=226584, but since it
occurs also for .ecore files I was wondering whether it is an EMF issue
(found nothing in bugzilla), or whether it actually belongs over in
platform.ui?
Regards
Tor

Tor,
This behavior is indeed involved because of several projects are
defining their own content provider for the Project Explorer (which is
using the Common Navigator Framework capabilities).
In the ecore case, there is one provided by Ecore Tools, another one
provided by the EMF Editor provided by GMF as an example.
In the uml diagram, the UML2 Tools project has defined many diagrams
each one providing a new content provider for both the domain model
(*.uml) and its asssociated diagram model (*.*_diagram). (This is
completely linked with the bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=226584 as you guess).
However, this can be fixed. You can indeed choose what you want to show
or not in this view : see
http://wiki.eclipse.org/EcoreTools_FAQ#Views_problems
Regards,
Jacques
