BPMN2 — Lanes and Sequence Flow

  • Key: BPMN2-147
  • Legacy Issue Number: 14696
  • Status: closed  
  • Source: International Business Machines ( Ms. Suzette Samoojh)
  • Summary:

    As per the current spec, a Lane references FlowElements. But FlowElements include SequenceFlow, which introduces issues given that SequenceFlow can span Lanes (e.g. the source is in one Lane while the target is in another).

    Recommendation: The spec text should indicate that SequenceFlow are not included in the list of FlowElements referenced by a Lane. Tools are then responsible for presenting and laying out the SequenceFlow appropriately, based on its source and targets.

  • Disposition: Resolved — BPMN 2.0
  • Disposition Summary:

    Lanes will reference FlowNodes, which exclude SequenceFlows (only activities, events and gateways are FlowNodes).
    We will change the semantic metamodel to reflect this change.
    a) in Figure 10.122 - The Lane class diagram , replace FlowElement with FlowNode
    b) below Figure 10.122, replace Flow Element with FlowNodes in these sentences:

    • "Each LaneSet and its Lanes can partition the Flow Elements in a different way."
    • "a tool can use to determine the list of Flow Elements to be partitioned into this Lane"
      c) in Table 10.128 - Lane attributes and model associations
      Replace flowElementRefs with flowNodeRefs, and FlowElement with FlowNode
      d) in Table 10.132 - Lane XML Schema
      Replace flowElementRef with flowNodeRef in this snippet
      <xsd:element name="partitionElement" type="tBaseElement" minOccurs="0" maxOccurs="1"/>
      <xsd:element name="flowElementRef" type="xsd:IDREF" minOccurs="0" maxOccurs="
      Disposition: Resolved
