Title: Why would connector DiagramID always be 0?
Post by: Aric Rohner on April 10, 2014, 06:25:38 am

Anyone know why the connector DiagramID always has a value of 0 in the following function?  Is there an alternative way to find out what diagram a connector is shown on?

Code: [Select]

function describeConnector( cnxn ) {
      
     var cnxn as EA.Connector;
     Session.Output( cnxn.ID + ", " + cnxn.Stereotype + ", " + cnxn.DiagramID );
}

Here is a sample of the output.

Code: [Select]

ConnectorID=1932, Stereotype=RDA_Includes1..1, DiagramID=0      
ConnectorID=1954, Stereotype=RDA_RefersTo, DiagramID=0      
ConnectorID=1948, Stereotype=RDA_Includes0..1, DiagramID=0

DiagramID property is Long type, but a connector can be shown in several diagrams, so it seems DiagramID is not the suitable way to find the diagram(s) in which a connector is shown.

MMoya is right. There's quite some rubbish left in the API. To find out where a connector is shown you need to

• find all diagrams where client and target are located
• check if it's not suppressed via DiagramLinks

Very tedious.

MMoya is partially right.

It's not used except for Communication Messages and Sequence messages. These messages only appear on one diagram (because they are representing a single sequence each) and will have their diagramid set.
