I switched from my own VIM setup to janus recently. I really like the organization.
When I tried to edit and save HAML files, I got following error.
Error detected while processing function <SNR>44_UpdateErrors..<SNR>44_RefreshSigns..<SNR>44_SignErrors:
line 12:
E474: Invalid argument
How can I fix this issue?
It was an error with syntastic plugin. I created an issue at GitHub.
scrooloose has fixed this issue. You can find the patch here
Simply run
rake
inside your ~/.vim directory. It'll update the syntastic plugin.
