Unwanted Side Efects When Changing ConnectorEnds

[Slávek Rydval]

I have a simple directed association between two classes. Then I change the c.ClientEnd.Navigable to "Non-Navigable" value within an addin method. As a side effect, EA changes connector's direction to the opposite one. Why?

The code in C#:


EA.Connector c = Repository.GetCurrentDiagram().SelectedConnector;
//now, the c.ClientEnd.Navigable == "Unspecified", c.SupplierEnd.Navigable == "Navigable" and c.Direction == "Source -> Destination"

c.ClientEnd.Navigable = "Non-Navigable";
//now, the c.ClientEnd.Navigable == "Non-Navigable", c.SupplierEnd.Navigable == "Navigable" and c.Direction == "Source -> Destination"

c.ClientEnd.Update();
//!!!now the value of c.Direction is "Destination->Source"!!!

c.Update();
Repository.SaveDiagram(Repository.GetCurrentDiagram().DiagramID);
Repository.ReloadDiagram(Repository.GetCurrentDiagram().DiagramID);


You get more side effects when you change OwnedByClassifier:

c.ClientEnd.OwnedByClassifier = true;
//direction and navigability is chagned


Is there any description how to proper change ConnectorEnds properties without these side effects?

Probably it's better to use Connector.Direction and change this accordingly. We don't expect any consistency in the API, do we?

Well, in case of using OwnedByClassifier the bahaviour is less predicable. I have this dialog and accept the side effects would be a pain in the ass:



So again, is there any description how to properly use ConnectorEnds?

Again: Connector.Direction produces correct results. Only G. Sparks knows why ConnectorEnd has redundant functionality that does not work. Ah! Hey! This is EA! D'oh!

Ok, cheers. I have to admin that there is wrong design of EA as many times before. :-(

Strange enough (ah, not really) that the connector dialog is as clumsy as it is after so many years so people are urged to make their own dialogs.
