It happens when parent epic has no labels.

You found a bug. It will be fixed in next version of the plugin. Anyway, as workaround, you can do the following changes in the configuration of your 4th post-function:

But we want to add parent labels to subtask without overwriting, So far we are just overwriting it, waiting for next release.

[Fidel Castro Armario]

Target field "New labels" doesn't overwrite sub-tasks labels, but simply add new labels to the existing ones. That's exactly what you want to do.

[BSPB Algo]

No, it actually does overwrite existing labels in subtasks.

Hi have tried to reproduce your problem using JIRA Workflow Toolbox 2.2.29 and JIRA 7.2.7, and in my case all is working correctly, as you can see in the attached video.

Please, double check your configuration. Maybe you selected Labels instead of New labels at target field.

If don't manage to solve the problem, I will be available for a video-conference with screen-share at Skype tomorrow, from 9:00 UTC to 13:00 UTC. My user is fidel100r.

[BSPB Algo]

Terribly sorry, I have indeed selected Labels. It is working.

[Fidel Castro Armario]

It doesn't matter. Glad to see you managed to make it work.

[Fidel Castro Armario]

Fixed in just released version 2.2.30.
