Displaying process instance information in Activtit Probe

[mproch]

Currently there is no way of showing process instances for given process definition in UI.

I made new tab in Activiti Probe, providing this functionality. In left menu there is process definitions list (as in Database tab). When one clicks on process definition table with basic process instance info is displayed.
It is also possible to display process diagram with current activities highlighted. I think quite many users would like this feature - it's present e.g. in JBPM.

Changes involved:
- activiti-webapp-probe & activiti-webapp - standard code displaying new table
- activiti-engine - small change to ProcessDiagramGenerator & ProcessDiagramCanvas, to highlight selected activities.
- activiti-webapp-rest - two new webscripts:
  - process-instances - using processInstanceQuery to get instances, it's possible to query by businessKey and processDefinitionId - so fairly standard thing I think
  - processInstance/{processInstanceId}/diagram - to display current activities on process diagram. This dynamically generates diagram, based on deployed ProcessDefinitionEntity

I decided to implement this stuff myself, as I'm showing Activiti on Warsaw JUG meeting next week - there will be comparison with IBM tools - so I thought that without any way of running instances I wouldn't make good impression
Now, I'd like to ask if there are any plans for such functionality - couldn't find it in roadmap. I think it would be good to include it in Activiti code base.

@Maciek: the history is always kept up to date with the runtime.
You can base your queries on the historicProcessInstance. Note that this will not work when people lower the history level to 'none', but thats shouldnt be a problem.

I made corrections Joram and Erik asked for, also adjusted displaying process definition version to look like in Explorer

When will this functionnality be released? I don't see it in the roadmap.

Thanks!

Hi,
it's already released in Activiti 5.2. But I was too lazy/overworked to document it - sorry 😕 User guide will be updated in upcoming release

Oh yes, I was with 5.1 version.
It's really great but an "autorefresh" feature would be awesome so we could follow the process progress in live! This is usefull when working with serviceTask.
Thank you for this feature anyway!
