audit rule doesn't work [message #198472]

Hello,
I have added audit rule according to instructions in GMF tutorial 3.But
it doesn't work.
My case:I want the node Kernel can have only 1 incoming arrow and 1
outgoing arrow.so I add OCL in Constraint liks this:
self.incoming->size() and self.outgoing->size()=1
and set the the right properties related Validation in .gmfgen.
What's do you think is the problem?

Many thanks!

Ye

Hello Ye,

try (self.incoming->size() = 1) and (self.outgoing->size() = 1)

Hello Alex,
However, this still doesn't work.Where else can be the reason?

Thanks a lot!

Hello Ye,

Try placing a breakpoint into the appropriate place in a code to see if constraint
was actually violated for any passed parameters..

Hi Ye Liu. IMO Alex wrote the constraint you need in the right form... so,
it's hard to understand where the problem is. What do you mean by "it
doesn't work"? What's the way you run your plugins?

Hello,
By 'It doesn't work' I mean,when I regenerate the .gmfgen file,then
generate the diagram package.And run the Eclipse application,the node
Kernel still can be connected by more than one incoming channels and
outgoing channels.

Hello,
I can't find a right way to set the breakpoint.But rather I found the
extension points in the plugin.xml in the diagram code a little bit
different from the GMF tutorial.The item under clientContext is selector
instead of enablement.I wonder if this show clue to the problem.
-----------------------------------------------------------
org.eclipse.emf.validation.constraintProviders
org.eclipse.emf.validation.constraintBindings
-com.eclipse.xxx.diagram.DefaultCtx(clientContext)
--com.eclipse.xxx.diagram.providers.xxxValidationProvider$De faultCtx1(selector)

Many thanks!

Hi, Ye,

The <selector> element is nothing but a Java alternative to the XML
expression of the <enablement> element. They are mutually exclusive and
serve the same function.

Luckily for you, the <selector> is easier to debug because you just put
a breakpoint in the referenced class :-)

Cheers,

Christian
