Hi. Apart from missing something, bpmn-moddle.umd.js does not let the possibility? of knowing if a sequence is flow is set to default (short line on flow) or conditional (white diamond).
At debugging time, I get an instance of ModdleElement that represents a sequence flow, but there is no attribute/function? to get the status of the sequence flow between: none, default (short line on flow) and conditional (white diamond).
BTW: I’m currently implementing a BPMN simulator.
PS : I have also the same issue with start events for instance, it seems that I cannot know the BPMN type among “conditional”, “timer”, “message”, etc. THANKS IN ADVANCE FOR ANY HELP!
