Problem description

When using helm to navigate the results of an rtags search (e.g., rtags-find-references-at-point), if I press on a search result line, the file opens normally. However, if I press (which opens the file, highlights the relevant line, and leaves the search results window open), I get the following error:

Error running timer ‘flycheck-buffer’: (user-error "Flycheck mode disabled") It's unclear whether flycheck is actually disabled at this point; since the buffer in question is not really open for editing (it disappears when you close the search results window), I'm assuming that this is occurring because it is read-only. Pressing on the line subsequently results in a buffer that appears to have flycheck enabled, although I'm not certain, since my configuration reloads a file upon saving, and I am relying on rtags checking upon save.

Expected behavior

No error

Actual behavior

The error appears

I'm not able to reproduce this. I don't normally use helm so I copied your setup for my test. I'm assuming you meant pressing tab here:

However, if I press (which opens the file, highlights the relevant line, and leaves the search results window open),

I only get a submenu saying:

[f1] Select [f2] Select other window

when I do that.

The same error with ivy (no helm). This is the configuration: `(require 'company) (global-company-mode) (require 'rtags) (cmake-ide-setup)
