What do you mean by connect two diagrams. Do you mean figures? - In that
case you must specify in gmfgraph that you only want one of the links to
show graphically.

You should really look in the tutorial, depending on your knowledge. In
gmfgraph you specify graphical element (including links). In gmfmap you
combine the graphics with tools. Then you generate. But again, this is
all covered in the tutorial:

hi..

I have gone through documentation.

Let me explain..

In my project i have many figures

for ex:

fig1,fig2,fig3,fig4 etc.

when i connect fig 1 and fig 2 it creates a single connection.

my project has feature where in i can add fig 1 and fig2 in fig3

and when i try to connect fig1 and fig2 which are now in fig3 .it shows
two connections ..

hope i am clear

Govind R.

Hi govind,

Did you try overriding:
CanonicalEditPolicy.shouldHandleNotificationEvent()return false;

Hi Govind,

Check your edit policies, and look for one edit policy which
extends CanonicalConnectionEditPolicy, (That is, The CanonicalEditPolicy
of the container of your links). And there will only be one class that
extends CanonicalConnectionEditPolicy for your digram. In that class
overwirde CanonicalEditPolicy.shouldHandleNotificationEvent(), and
return false;

It worked for me earlier, when I faced the same problem, hope
it helps you.

Cheers, Biju

i modified all the CanonicalEditPolicy in .diagram.edit.policies by adding ' protected boolean shouldHandleNotificationEvent(Notification event) {
return false;
} ' this sentence,it works!

the result is showing one link but it still report the errors in console 'java.lang.IllegalArgumentException: Argument not valid'
