Hi,
I have a problem with GMF (version 1.0.0.v200606261119 from the Callisto
update site) and the mindmap example (from the zip from the mindmap
tutorial page):
When I insert an Includes connection between two Topic nodes
I obtain two diagram links instead of a single one.
One has the correct label 'includes' the other one is unlabeled.
Any hints?

Thanks for your hint. The suggested solution works: only one link is
inserted as expected.
But there is a little problem left; my link object is missing its label.
The diagram link souhld look like as follows.
<edges xmi:type="notation:Edge" xmi:id="_0MUmMEdiEdu3qOjSl4MqCA"
type="3003" source="_YeaUsEdiEdu3qOjSl4MqCA"
target="_YSYq4EdiEdu3qOjSl4MqCA">
<children xmi:type="notation:Node" xmi:id="_0MUmNUdiEdu3qOjSl4MqCA"
type="4003">
<layoutConstraint xmi:type="notation:Location"
xmi:id="_0MUmNkdiEdu3qOjSl4MqCA" y="40"/>
</children>
<styles xmi:type="notation:RoutingStyle"
xmi:id="_0MUmMUdiEdu3qOjSl4MqCA"/>
<styles xmi:type="notation:FontStyle"
xmi:id="_0MUmMkdiEdu3qOjSl4MqCA"/>
<styles xmi:type="notation:LineStyle"
xmi:id="_0MUmM0diEdu3qOjSl4MqCA"/>
<element xmi:type="simpleusecase:UseCaseAssociation"
href="default2.simpleusecase#//@associations.1"/>
<bendpoints xmi:type="notation:RelativeBendpoints"
xmi:id="_0MUmNEdiEdu3qOjSl4MqCA" points="[11, -23, -54, 155]$[115, -176,
50, 2]"/>
<sourceAnchor xmi:type="notation:IdentityAnchor"
xmi:id="_0MUmN0diEdu3qOjSl4MqCA" id="(0.78,0.575)"/>
</edges>
Unfortunately the <children> element is not inserted in the diagram.
Any further hints?
Yours,
Alex

I examined two solutions, namely (1) changing
MapCanonicalEditPolicy.refreshConnections as suggested in
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg00476.html
and (2) adding MapCanonicalEditPolicy.shouldHandleNotificationEvent
https://bugs.eclipse.org/bugs/show_bug.cgi?id=148021.
Both approches a partial solution to the problem: Only one link is
inserted, but its label is missing.
Comment #9 from Alex Shatalin in the bugzilla entry
https://bugs.eclipse.org/bugs/show_bug.cgi?id=148021 mentions that there
is a modified zip for the mindmap tutorial:

I re-load mindmap_tutorial_2.zip (and mindmap_tutorial_3.zip) but the
fix does not work, the mindmap tutorial still produced dublicate links
(without an lables).

Ok, I tried again to reproduce the problem.
I installed the current version of the mindmap example from the
specified URL in a fresh Eclipse 3.2 SDK (windows) with the Callisto
version of GMF 1.0 and its prereqs.
(To verify whether I am using the correct version of the file
mindmap_tutorial_2.zip: The size of the file is 641.654 bytes and its
md5 checksum is 3b575f22cd2577563f5d4612c78fe5f7.)
The result:
The "includes" links in the mindmap diagram editor are working fine,
but "extends" links are broken. Adding an "extends" link
inserts two parallel links without labels.
(I attached the model files representing a tiny example with two Topic
nodes with a correct "includes" link and a broken "extends" link.)
BTW, are you working with Mac OS X?
Yours,
Alex

Hi Alex,
It seems there is a problem with the tutorial step 2 solution zip files, so
if you can use the final solution files, or get the latest from the 1.0.1
maintenance branch from CVS, it should work correctly. I'll be updating the
tutorial soon for the 2.0 stream, and will likely remove these intermediate
solution files.
Thanks,
Rich
