Activiti process model interaction/global perspective (read content for clarification)

Activiti Community,I am exploring BPM capabilities for possible use in our small IT company.

Ah, I wish I could edit posts. I just want to emphasize that what we'd like is to be able to view, as a model or diagram, process *instances* that visually show which stage a given process is in.

Activiti explorer now uses a javascript-based rendering of a process-model. Active steps can be highlighted if needed, and additional information about a step (description, …) is show when hovering an activity. You see the whole process-diagral this way. Take a look at org.activiti.explorer.ui.management.processinstance.ProcessInstanceDetailPanel:158 (addProcessImage) for an example of how a diagram-viewer URL is constructed.

An alternative is to have a static image (PNG) rendered which highlights the current active activities (based on an process-instance ID) using our API. For this approach, take a look at the org.activiti.engine.impl.bpmn.diagram.ProcessDiagramGenerator class and to org.activiti.rest.service.api.runtime.process.ProcessInstanceDiagramResource (REST-resource for getting this PNG image for a process-instance) to see how the generator can be used to create PNG's based on a process-instance ID. Or you can even just use this activiti-REST endpoint in your webapp instead…
