Bump? Seems like an easy thing to fix (I hope) in order to make Blue Ocean much more valuable to us. It's been almost 2.5 years since this was posted, and this minor but meaningful bug is still ... well, bugging us. 

Put another way, the following process sucks:

• build a pipeline in Blue Ocean
• get it working
• move it into a folder
• use it for a while
• if you only use it for a short time, like an hour, and you need to modify it, move it back out of the folder so you can go back to the editor
• if you use it for a longer time, like a year, and you need to modify it, stare at the place where the pencil icon is supposed to be and wonder what the hell happened

I know this is a small bug, but I would certainly like it addressed. The above process just sucks too much - it makes me almost want to just toss Blue Ocean altogether, in spite of its obvious value, when I have a lot of work going on in Jenkins.

Thanks for considering this.

The issue seems to be right here in loadPipelineMetadata(), loadBranchMetadata() and save(...) when the / is used for splitting and group 0 assumed to be the team:
https://github.com/jenkinsci/blueocean-plugin/blob/master/blueocean-pipeline-editor/src/main/js/EditorPage.jsx#L300

const split = pipeline.split('/');
const team = split[0];
(const repo = split[1];)

which is used as a pipeline name here:
https://github.com/jenkinsci/blueocean-plugin/blob/master/blueocean-pipeline-editor/src/main/js/EditorPage.jsx#L619

A simple fix might be to use every element of the split except for the last one for the team and the last element for the repo. Not sure if this might break something else. But from a quick overview of the code it does not look like it

Here it seems to be implemented correctly with the branch name being spliced of the end of the pipeline name: https://github.com/jenkinsci/blueocean-plugin/blob/master/blueocean-pipeline-editor/src/main/js/PipelineEditorLink.jsx#L33

thanks for the PR
