AEM 6.3 SP1 RTE Issue

Can you provide more information, I don't it will help anyone to understand the issue.

Screenshots or more detail description will be helpful

Can you check the error message in AEM error.log? Please share the Steps to reproduce it.

I have just tested it on AEM 6.3, it is working fine.

Please install this package:- Configuring Experience Manager Rich Text Editor Plugins in a Touch UI Component Dialog and confirm.

Thanks for posting the solution.

Is this issue resolved with AEM 6.3

"I was having an accordian where I had multiple RTEs on slecting any random text and on clicking  hyperlinks it was automatically shifting the control to the last RTE."

Yes.
the issue persisted in AEM 6.3 only.However solved now.
It had some issue with the UI.
It can be resolved by overriding the js for the dialog.

Are there any hot fixes or service packs that resolve this issue. I hope to try with SP1 or CFP 2.0

you can try it but as far as I remember they couldnot help me.
I had to write an external js.

Will you be able to share the external js file

Sure.
Following is the code snippet:

$(document).on("dialog-ready",function(){

    var originalEvent=Vent.prototype._executeBubbleListeners

Vent.prototype._executeBubbleListeners = function(event){

    if(event.type!="mousedown") {

  originalEvent(event);

    }

}

})

This shall work.Lemme know if it works.
you must handle the exceptions as well later for js.
