Hi,

I’m trying to change process version from history dropdown but it always present the latest one.  
 ![image](https://cdck-file-uploads-canada1.s3.dualstack.ca-central-1.amazonaws.com/flex035/uploads/flowable/original/1X/ab9596f6ff1791b07a10925858d2dfd2bbf28a77.png)

Does anyone use this version control and know if there is any workaround ?  
I’m using Flowable-modeler 6.3.1

It looks like version is changed under the hood (but it shows latest one) cause when I click version 2 or 1 of my process and then try to download process definition I receive the following issue:

I’ve found the pull request for the second issue [https://github.com/flowable/flowable-engine/pull/1093](https://github.com/flowable/flowable-engine/pull/1093) .  
So it’s fixed 🙂 but does it also fix the issue with version changing ?

I think that there was no problem with the version changing. Only with how it was retrieved, and that was not working 🙂. Try to hit the endpoint from the browser with the correct path and it should be there

Nope. It doesn’t work or I missed something ;(

Hi,

From your screen capture I would say that there is a bug in the history selection. Could you create an issue on Github with a link to the screen capture? Then we can track it and make sure it gets resolved.

Best regards,

Tijs
