[Dojo-interest] Editor2 Bug and Workaround

[Wolterink Webdesign Postmaster]

The file /src/widget/templates/richtextframe.html
contains the following code:


<script type="text/javascript">
     function init(){
        document.designMode = 'On';
        parentPageDomain = document.location.href.split('#')[1];
        if (parentPageDomain) {
           document.domain = parentPageDomain;
        }
     }
     window.onload = init;
</script>

When you try to load a Editor2 component that is invisible (for
example behand a Tab), you will get the following exception in firefox 
  1.5:

uncaught exception: [Exception... "Component returned failure code: 
0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMNSHTMLDocument.designMode]" 
nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: 
http://localhost:8084/XDataSystem/standard/js/dojo/src/widget/templates/richtextframe.html# 
:: init :: line 9" data: no]


This is due to a bug in Firefox. Setting
designMode='On' on an invisible document will
throw this exception.

The workaround is as follows:


<script type="text/javascript">
     function init(){
        //document.designMode = 'On';
        parentPageDomain = document.location.href.split('#')[1];
        if (parentPageDomain) {
           document.domain = parentPageDomain;
        }
     }
     window.onload = init;
     window.onfocus = function() {
	document.designMode = 'On';
     }
</script>

Now designMode will be toggled on when the
document gets focus... This is wat you want, and
will not throw the error. ( a document cannot get focus
when it is invisible).

I don't know how to add this to the sourcebase of dojo....
Can anybody add it?

Thanks in advance.
