Insert Link button disabled

I have never seen this before. Could it be you template that is preprocessing the form or something? Does it work if you change to a default theme?

This is happening to me as well. I can't paste any link into the link field because it is disabled. If I start typing in that field the "Insert Link" button becomes enabled, but I still can't paste into the link field.

I'm using it with a Body field that uses TinyMce + WYSIWYG module. I'm using the default seven theme.

Disregard my comment. It is working fine for me.

It happens when you use mouse right click to paste the link without any keyboard input. The button works fine if you use keyboard to paste

Hopefully this patch fixes the problem by changing the validation handler attaching to .change instead of .keyup.

Marked #2184277: Pasting with mouse right-click doesn't activate 'Insert link'-button as duplicate. That issue also have a patch.

$('#edit-linkit-path', context).bind('keyup paste input propertychange', function(){
      Drupal.linkit.requiredFieldsValidation();
    });

solves it in all browsers.
