IDE Error with RubyMine version 2018.1 EAP [bug]

[thestelz]

Sorry to bother again, but I'm getting the following IDE Fatal Error:

Railways version: 0.8.10

I'm not sure what happened, but I copied a path name (company_profile_change_path) and went to paste it into the search box and then it errored out.

RubyMine info:

After restarting RubyMine, it fixed the issue. Not sure if you still want this ticket open as I'm not sure if I can replicate it or if it was something to do with something else

[thestelz]

@basgren I haven't had this issue for a while now and I'm even on a newer version of RubyMine. Sorry for being on the trigger a bit to early on this one. I can't even replicate it at all.

RubyMine 2018.1 EAP

You can close this issue out if you want as I'm not sure if you still want it open for some reason.

Thanks!

[basgren]

Thanks! I will take a look at it. I didn't investigate it before as early IDE versions are changing under the hood, so I prefer to wait for more or less stable build. But as the issue happened again - it's time to dig in :)

[valich]

Is this problem stably reproduced? I suppose it might be related to the stubs problems. It does not look like railways plugin is responsible..

[thestelz]

@valich I only have EAP versions of RM, so I'm not sure if it's in the stable versions or not.

That's why I said I couldn't replicate it on EAP versions anymore[1,2] and didn't want to waste @basgren time.

(ref: 1, 2)

[basgren]

Unfortunately, I couldn't reproduce the issue. Tried both 2018.1 and 2018.2 EAP versions. So I'm closing it for now. Feel free to reopen if the issue can be reproduced.
Thanks!
