Hi all,
I have an error in IE (only) when run dr.render('dr'). I'm using the version 7 of IE. In firebug it works perfectly.

Where dr is:
var dr = new Ext.FormPanel({
    labelWidth: 125,
    frame: false,
    header: false,
    border: false,
    bodyStyle:'padding:5px 5px 0',
    width: 350,
    defaults: {width: 175},
    defaultType: 'datefield',
    items: [{
        fieldLabel: 'Start Date',
        name: 'startdt',
        id: 'startdt',
        vtype: 'daterange',
        endDateField: 'enddt' // id of the end date field
        fieldLabel: 'End Date',
        name: 'enddt',
        id: 'enddt',
        vtype: 'daterange',
        startDateField: 'startdt' // id of the start date field
The div exists when I render the formPanel on it.

Using Companion.JS debugger for IE, I get the following message:
Unknown runtime error (line 318) (ext-all-debug.js)

    overwrite : function(el, o, returnElement){
        el = Ext.getDom(el);
        el.innerHTML = createHtml(o);
        return returnElement ? Ext.get(el.firstChild, true) : el.firstChild;
Doubleclicking on the error I have some more messages (the error comes from this).

ext-all-debug.js (line 3785)
ext-all-debug.js (line 15892)
ext-all-debug.js (line 15958)
ext-all-debug.js (line 28809)
ext-all-debug.js (line 12454)
ext-all-debug.js (line 14062)
cap_eu_browse_list.html (line 42) it is parent.dr.render('dr');

Any idea of why is it failing? I've spent almost all the day with it, but I didn't find the fix.
