[News.eclipse.technology.gmf] Re: two figure for a connection + Source E

["Radek Dvorak" <radek.dvorak@xxxxxxxxxxx>]

Hi Angelo,

There is a couple of reasons why it is not working as you expect.
First, in case that a link mapping uses 'sourceFeature', incorrect
context is used for the source end (derived from the containmentFeature) in 
the generated code.
This has been fixed as https://bugs.eclipse.org/bugs/show_bug.cgi?id=148818 
and
will arrive in 1.0.1 soon. You can check GMF downloads page for maintenance 
builds containing
the fix.
With this fix your models allow only links creation started from the Square 
source and
targeted to Circle. Those source ends which do not satisfy the source 
constraint prevent the connection
from starting but disallow cursor is not shown while internally, the 
constraint evaluates correctly.
I guess, the problem of the 'disallow cursor' was described earlier in this 
newgroup.

Regards,
/Radek

In the attachment I've put the whole model that I use for this example.
With both the constraints I can't make any kind of link.
BYE
