#3958: Creating more than one instance during runtime kills the former instances

Browser: Firefox 3.5
OS: Windows XP
Version fo CKEditor: 3.0 RC
I have a page with one editor instance. When clicking a button, I want to
add another editor instance. This is being done by
inserting new textareas via JavaScript and then replacing them via
"CKEDIOTR.replace([name of textarea])".
This does work fine when creating only one new editor instance. But when I
want to create one more editor instance, this new editor works fine, but
the editor being created before this editor does not work anymore. Not
working anymore means that only the editor's control buttons and theme are
visible but the white input area is missing completely. In Firefox' error
console the error "i.contentWindow is null" (file ckeditor.js line 18) is
being shown.
Demo source code:
{{{
<html>
<body>
<input class="Button" type="button" value="New Editor"
onClick="javascript:addEditor()" /><input class="Button" type="button"
value="New Editor (Alternative)" onClick="javascript:addEditorAlt()" /><br
/>
<textarea name="editor_0" id="editor0" cols="70" rows="3"></textarea>
<div id="area" style="border:thin solid black;">this is a div</div>
<script type="text/javascript"
src="./script/ckeditor/ckeditor.js"></script>
<script type="text/javascript">
<!--
var editorInstances = new Array();
editorInstances[0] = CKEDITOR.replace('editor_0');
editorCount = 0;
function addEditor() {
editorCount += 1;
area = document.getElementById("area").innerHTML + '<br
/><textarea name="editor_'+editorCount+'" id="editor_'+editorCount+'"
cols="70" rows="3"></textarea>';
document.getElementById("area").innerHTML = area;
CKEDITOR.replace('editor_'+editorCount);
}
function addEditorAlt() {
editorCount += 1;
area = document.getElementById("area").innerHTML + '<br
/><textarea name="editor_'+editorCount+'" id="editor_'+editorCount+'"
cols="70" rows="3"></textarea>';
document.getElementById("area").innerHTML = area;
for (i = 1; i < editorCount; i++){
alert("destroying editor "+i);
editorInstances[i].destroy();
alert("editor "+i+" successfully destroyed");
editorInstances[i] = 0;
}
editorInstances = new Array(); //reset collection of
editor instances
for (i = 1; i <= editorCount; i++){
alert("creating editor "+i);
editorInstances[i] =
CKEDITOR.replace('editor_'+i);
alert("destroying editor "+i);
editorInstances[i].destroy();
alert("editor "+i+" successfully destroyed");
editorInstances[i] =
CKEDITOR.replace('editor_'+i);
}
}
-->
</script>
</body>
</html>
}}}
When clicking on the first button, a new editor is being added. After the
second click, one can see that only the very first and last editors work
properly but the ones in the middle do not work any more.
I tried to implement an alternative in function "addEditorAlt" - but this
doesn't work either. Basicly, it saves all the opened editor instances
into an arry and before creating a new one, it tries to destroy all the
old ones.
