Cannot paste text in CodeMirror in Google Chrome

Question

There was no problem some months ago but suddenly "Paste" stop working in CodeMirror in Google Chrome. Both "Ctrl+V", "Shift+Insert" and right-click -> "Paste" do nothing.

It's not a bug in my code because even at demo page at
http://codemirror.net/jstest.html
it doesn't work.

Answer 1

Update Google Chrome. Everything works in the new version - Google Chrome 8.0.552.0 dev

Answer 2

This problem continues on Linux when using any webkit variant (Chrome is one). It remains unhandled in CodeMirror 2.25.

Here is the bug.

You can make a VERY PARTIAL patch to handleKeyBinding(e) in CodeMirror after var name=... This is NOT a perfect fix, but it will help you recognize Delete, Ctrl+Insert and Shift+Insert:

if( name == null && (webkit || chrome) && e.keyCode == 0 && e.charCode == 0 && e.keyLocation == 3 ) {
    // Now we know something on the keypad has been pressed and not translated properly by webkit.
    if( e.ctrlKey == false && e.shiftKey == false ) {
      // We're probably hitting the Delete key to delete a character.
      name = 'Delete';    
    }
    if( e.ctrlKey == true || e.shiftKey == true ) {
      // We're probably using Ctrl-Ins to copy, or Shift-Ins to paste.
      name = 'Insert';    
    }
  }    

Now Delete is handled. But since you can't get to the clipboard from Javascript, you are stuck with respect to Ctrl+Insert (copy) and Shift+Insert(paste) until the webkit bug is fixed.

I have the same problem - however, I found this instance of it does accept copy-paste from within chrome.

I've tried to use their copy of the chromemirror source code on my site - but no luck yet
