Hi all. I’ve been working in Capella for a couple hours, and I ran into a bug where my right-click has stopped working in most places in Capella. Key areas where it doesn’t work: Project Explorer, Diagrams, Semantic Browser. Some areas where it still works: the “Information” window, Property windows, empty spaces of toolbars, window tabs, git History.
I tried a new workspace, and right click appears to work everywhere there, so I could scrap my workspace and create a new one. Any ideas how this might have happened or how it could be corrected?
I have never heard of such a problem. Have you tried to just close and restart Capella? (without changing workspace) - is the problem still there?
Stephane
Hi Stephane 
I did a closed/reopen of Capella and rebooted Windows, too. Neither made a difference. I’m messing around (just trying to right click a lot), and got some wrong context menus, too. See below, for example.
Another breadcrumb: I’m getting a lot of entries in the .bak_0_.log file in the workspace/.metadata folder. From what I can tell, they all are like the one pasted below. I was doing a lot with m2doc when this happened, so it seems reasonable that it could be related. I’ll keep poking around, but I’m eager for any suggestions!

thanks, asking internally if someone may have an idea of the root cause…
Thanks Stephane. I think I’m out of the woods and up and running again. I was worried about messing up something I had setup, especially because I had projects tied to git repos, but things worked out! m2doc is working, too. Here’s what I did:
- I uninstalled and reinstalled m2doc. This didn’t seem to change anything from what I could tell, but I don’t know for sure.
- I created a new workspace, where right click worked like it should. I created a new project just to test out right-click some. After testing it out some, I deleted the project.
- Outside of Capella in the file explorer, I copied the .metadata, MDEReport.html, and Usage.log files (the files that seemed to contain workspace-specific data in my mind) from the new, blank workspace to my old, problematic workspace - overriding those files in the old workspace (I think I actually manually deleted them out of my old workspace first, in case file names weren’t identical).
- I then loaded up my old (now with workspace data overwritten) workspace folder into Capella. Because I overwrote the workspace files, in Capella’s project explorer the workspace didn’t have any projects in it initially. It was no problem to bring in the ones I wanted.
- Things seem to be good now - right click, m2doc gen, and git connection are working.
This felt a little touch-and-go, but seemed to get me back to where I was. Make sure you always have a backup or two before messing around!
Nicely done! Thanks for sharing. Not sure we’ll be able to sort that out, but I will let you know if I receive any feedback!
Yes, always have a backup - there are different options in Eclipse/Capella for backuping your work, but I see you are using Git so that’s a great security!
The feedback I got is that we’ve never seen this problem, something odd probably happened… Unless you had a problem with your initial M2Doc installation.
If the problem happens again or if you have a way to reproduce it, we’ll be interested if you let us know.
