Colin,

I accomplished this using the Snip_WorkflowView_TaskTimeLineOnly snippet in the Workflow Commons module.  This snip provides the following kind of view:

Using this snip as a starting point, you should be able to get the timeline information you are looking for.

Hope that helps.

I think I have an answer for you Colin but it depends how many entries you have.  Within Mendix go to your App and go to Collaborate / General Settings.

In here there is a menu item at the top called History.  This contains what you (and I) need (needed).  I didn't have tooooo many pages so was able to extract manually by page (cause I need it today, and nobody else had asked the question or answered you).  You might be clever enough to be able to automate getting these out quicker than I did.  Hope that helps (automate advice welcome if you solve it).

I use a microflow to associate the object with the workflow as the first action in the workflow. Thanks to Daniel for confirming this approach

Hi Colin, I want to retrieve workflow from my object too, but how did you creat the association between workflow and your entity, cause the workflow is in the system domain and I have no access to change it.
