Not working undo/redo for multi-instance

[shibaaboy]

Describe the Bug

When I set a Task or SubProcess as multi-instance and change the type (parallel or serial) and then use undo/redo, there is no visual change (parallel or serial is not shown).

Steps to Reproduce

Click on A Task
Mark it as multi-instance using the replace menu
Use undo/redo -> no visual change

I cannot reproduce it at https://demo.bpmn.io/s/start

[barmac]

What's your setup? Are there any errors in the developer tools?

https://demo.bpmn.io/s/start - url
if i use undo/redo - no visual change (parallel or serial)

Type icon doesn't change when i use undo/redo

[shibaaboy]

1. add a task or subprocess
2. change type - parallel -> Task/SubProcess with icon or
3. change type - serial -> Task/SubProcess with another icon
4. use undo (command + z) -> no visual change ( type must be parallel )
5. use undo (command + z) -> visual change ( without type )

when undo/redo changes in sequence types are not shown

[barmac]

OK I can reproduce it now. So I need to change first to parallel, then to sequence. Thanks for a clear way to reproduce it.

Could you please assign this to me? I'm interested in taking it on. Are there any specific timelines for its completion or release?

[barmac]

Hi, feel free to prepare a PR. As long as there is no in progress label, we are not working on this.
