Same name for multiple connections

SysML v2 Questions / Help
1

Hello there,
I am trying my first steps and have some problems to get everything working.
From my understanding, a port can have multiple connections to different ports. Also from my understanding, SysML2 should support to have the same name for the connections, too.

Short example:

package test_multiconnection {
private import ScalarValues::*;

package Interfaces {
    /* Definition of what is exchanged */
    item def Power12V;

    port def Power12VInPort {
        in item Power : Power12V;
    }

    port def Power12VOutPort {
        out item Power : Power12V;
    }
} // package Interfaces

part def Main_Connector {
    attribute partName : String = "Tyco 22+2pins (2404849-1)";
    port BA : Interfaces::Power12VOutPort;
}

part def RPP_IDC {
    attribute partName : String = "MPQ5852";
    port Vin : Interfaces::Power12VInPort;
    port Vout : Interfaces::Power12VOutPort;
    port EN : Interfaces::Power12VInPort;
}

part mainConnector : Main_Connector {
}
part rppIdc : RPP_IDC {
}


connection BA connect mainConnector.BA to rppIdc.Vin {
    flow of Interfaces::Power12V {
        end ::> source;
        end ::> target;
    }
}

connection BA connect mainConnector.BA to rppIdc.EN {
    flow of Interfaces::Power12V {
        end ::> source;
        end ::> target;
    }
}

view partsAndConnectionsAllInstancesView {
    render Views::asInterconnectionDiagram;
    expose mainConnector;
    expose rppIdc;
    expose BA;
}

}

As you can see, there are 2x connections with the name BA. I only get 1 shown in Tom Sawyer (with rightclick “visualize element (labs)”-> “as nested diagram” , the second one is missing.

When using the CLI I also get the error:
C:/…/test_multiconnection.sysml:42:16: error (namespace-distinguishability): Member name ‘BA’ shadows test_multiconnection::BA
Aborted: 1 error in model. No output written.
Error: syside-drawer exited with code 1

I assume this is an issue on how the tooling handles namespaces, but my question is more: Is this according to SysML2 AND what would be a solution, if I need the name to be the same?

Yes, diagnostics are according to the specification because namespaces cannot have multiple members with the same names. They need to have distinct names, or have no names at all.
