Swimlanes seem to be ignored

[michj_74]

Hi,

when I deploy the following process in Activiti Explorer it is deployed but I don't see the swimlanes in the process picture and when I start the process the swimlanes seem to be ignored. I'm using activiti 5.12.1. Are swimlanes currently supported?

Here is my process definition:

No, swimlanes are indeed not generated by the Activiti process diagram generator

The cheesy answer would of course be we welcome any contribution. I won't do that.

i need demo example of swimlanes (pool,lanes)….because i new in activiti i find it but i am not getting example of pool and lanes…

Hi,

thanks for your answer. Perhaps my question was not precise enough. What I actually was interested in is whether swimlanes are supported by the Activiti engine itself?

Thanks,
Mike

Hello Mike,

AFAIK they are not supported by the engine itself. So you have to define the task assignment for each user task on the user task itself by using the BPMN 2.0 or Activiti attributes.

If your question is about specifying the user assignment on the swimlanes instead on the tasks:

We are using an XSL transformation before deploying process definitions to Activiti to achieve this. The transformation takes the assignment specified on a swimlane attribute and puts it in the task attributes of the tasks which are located within the swimlane.

HTH,
Sebastian

Hi Mike,

In the Activiti Engine pools do make a difference. So if you would model a process with 2 pools (with each 2 lanes) for example, the Activiti Engine would see this as two different process definitions, one per pool. If you model a process with one pool and multiple lanes, it's just parsed as one process definition.

Best regards,

[michj_74]

Thank you guys for quick answers!

@Sebastian yes that's what I also was thinking about, so seems like I was not so wrong.

Cheers,
Mike

Seems like Swimlanes rendering and processing is currently not supported in 5.13? Is there an open ticket for this behavior? I checked https://github.com/Activiti/Activiti/issues but found nothing.
