I am having an issue with integrating Code Mirror into a Bootstrap tab.
The problem is that because the Bootstrap tab is not set to active, code mirror will only display the content if the user clicks on it.
I have thoroughly searched a solution for the problem but have not found anything that works (possibly due to my knowledge about JavaScript not being very good). I have tried things like telling codemirror to refresh, but it doesn't solve the problem.
Calling .refresh() on the editor is what is needed here. You just have to make sure you do it after the editor actually becomes visible. I am not sure how to do this with Bootstrap tabs, but I'm sure there is some way to listen to tab change events.
