How to use Connector.Update right?

[B27]

Hello,

I'd like to add a new connector to a package. But I'm getting an error when trying to update the connector. My code looks like this:

Code: [Select]

con = package.Element.Connectors.AddNew("name", "type")
con.Update
The error: OLE error code:61704 in EA
  Internal application error.
HRESULT error code: 0x80020009
Exception error occured.

I am working with Ruby and up till now everything worked fine with the EA API, Update on other collection objects worked as well. So maybe I am doing something wrong here?
Thanks for your help.

You have to set the Connector.SupplierID before saving, and the "type" of your connector is not one of the known types.
According to TFM the type should be one of:

Aggregation
Assembly
Association
Collaboration
CommunicationPath
Connector
ControlFlow
Delegate
Dependency
Deployment
ERLink
Generalization
InformationFlow
Instantiation
InterruptFlow
Manifest
Nesting
NoteLink
ObjectFlow
Package
Realization
Sequence
StateFlow
UseCase

Thanks for your answer, Geert.
I tried it like you proposed:

Code: [Select]

con = package.Element.Connectors.AddNew("name", "Aggregation")
con.SupplierID = package2.Element.ElementID
con.Update
And I'm getting the same error as before. Tried it with setting the ClientID and SupplierID as well.

Why do you use Package.Element.Connectors and not simply Package.Connectors?

Also in a strong typed language you have to cast the object returned by the Collection.AddNew() operation to Connector.
So something like

Code: [Select]

con = (Connector)package.Connectors.AddNew("name", "Aggregation")I'm not sure how that works using Ruby.

I had a look at the sample code from Sparx. They use the element and not the package. But I tried it without using element and instead the package.Connectors directly. Doesn't work either.

As far as I know there is no type-cast like that. But I checked which class type the connector has: IDualConnector. And I think, that's what it's supposed to be.

Then I'm all out of ideas.
Better ask Sparx Support for help.

Thanks for your help anyway.
