Hello

I am trying to attach two labels to a connection, but just one is displayed. I've tried several things now and I am wondering if this is actually possible?

Attached are the snippets which i thought should describe this.
Thanks!!

gmfgraph:

[...] 
<descriptors
        name="RelationConnectorFigure">
      <actualFigure
          xsi:type="gmfgraph:PolylineConnection"
          name="RelationConnectorFigure">
        <children
            xsi:type="gmfgraph:Label"
            name="ConnectorRole"/>
        <children
            xsi:type="gmfgraph:Label"
            name="RelationConnectorCardinality"
            text=""/>
      </actualFigure>
      <accessors
          figure="//@figures.0/@descriptors.2/@actualFigure/@children.1"/>
      <accessors
          figure="//@figures.0/@descriptors.2/@actualFigure/@children.0"/>
    </descriptors>[...]

  <connections
      name="RelationConnector"
      figure="RelationConnectorFigure"/>
  <labels
      name="RelationConnectorCardinality"
      figure="RelationConnectorFigure"
      elementIcon="false"
      accessor="//@figures.0/@descriptors.2/@accessors.0"/>
  <labels
      name="ConnectorRole"

Hello,

This is definitely possible, U2T associatoins has 7 different labels each Smile

Just use separate figure descriptors for labels instead of child labels and the accessors, like below:

  <figures
      name="AssociationsGallery"
implementationBundle="org.eclipse.uml2.diagram.common">
    <descriptors
        name="Association_label_name">
      <actualFigure
          xsi:type="gmfgraph:Label"
          name="Association_label_name"/>
    </descriptors>
    <descriptors
        name="Association_label_sourceRole">
      <actualFigure
          xsi:type="gmfgraph:Label"
          name="Association_label_sourceRole"/>
    </descriptors>
    ... 5 labels skipped 
    <descriptors
        name="AssociationClass2RhombConnectorFigure">
      <actualFigure
          xsi:type="gmfgraph:PolylineConnection"
          name="AssociationClass2RhombConnectorFigure"
          lineKind="LINE_DASH"/>
    </descriptors>
  </figures>

Everything else would be the same as in your samples.

Regards,
Michael
