Impl Setter not called by diagram [message #697400]

Hi,

Used to use GMF a bit more back in about 2007.
Just done a new diagram and put a breakpoint on a setter for an attribute in the impl class.
I launch in debug mode, add a node and charge the variable (which I am hoping would call the setter). But the breakpoint is never triggered.

Any ideas ?

Thanks,

Stu

Stu,

Is the changed value showing up in the serialization if you save? If
you set a breakpoint in the constructor for that class, is that getting hit?

It does get saved and when I re-open the diagram it is set.

What I am talking about is during editing when I change an attribute on a node, the setter in the nodes impl class doesn't seem to get called.

On one of my old (maybe GMF 2.1) the impl classes had a
public void eSet(int featureID, Object newValue) {
switch (featureID) {

method which would farm the features off to each setter.

But with the new version I cannot see this method it seems to go through:-
eDynamicSet(dynamicFeatureID, eFeature, newValue);
but that doesn't call the setter in the NodeImpl class.

I get the feeling I must have missed something in one of the mapping model files.

Then clearly something is being set.

Is this really on a node or in your model itself?

Yes, each implementation class with features does this.

If the implementation class defines getters and setters there must be
reflective code to correspond...

It's hard to map all this onto your comment about a setter not being
called. Maybe you've set the breakpoint in the wrong class. Clearly a
value is being set...

So it's not a feature of that specific class. I'm still not sure how
this is relating to your original issue.

Well the only way I found to resolve this was the re-enter the Ecore model and regenerate through once more. Can't tell you why that fixed it but it did.
