Hi Trevor,

You are correct, due to the same concerns the issue is logged as a bug report. As I noted, this is a matter that ConvertToXhml filter should be able to handle without alerts or errors.

The provided feedback item (http://feedback.telerik.com/Project/108/Feedback/Details/137856) enables you to track any updates on the task and workaround the problem via the provided temporary resolutions. I suggest using the second one as it is indented to fix the issue within the ConvertToXhtml logic, rather disabling it:

<telerik:RadEditor ID="RadEditor1" runat="server">

<Content>

<p> <h2></h2> <h2></h2> </p>

</Content>

</telerik:RadEditor>

<script type="text/javascript">

Telerik.Web.UI.Editor.NestedElementsFix.prototype._shouldRemoveBlockElement = function (element, elementChanged) {

var utils = Telerik.Web.UI.Editor.Utils;

if (!elementChanged || !element) return false;

if (!/^li|td|th$/.test(element.nodeName) &&

utils.isNodeEmptyRecursive(element) &&

!$telerik.$(element).find("ol,ul,table,h1,h2,h3,h4,h5,h6").length) {

return true;

}

return false;

}

</script>

I've implemented the suggested code fix, but the problem remains. Here's the code from my test aspx file which I copied directly from the suggested solution:

<html>
<body>
<form runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<telerik:RadEditor ID="RadEditor1" runat="server">
    <Content>
    </Content>
</telerik:RadEditor>
</form>
<script type="text/javascript">
    Telerik.Web.UI.Editor.NestedElementsFix.prototype._shouldRemoveBlockElement = function (element, elementChanged) {
        var utils = Telerik.Web.UI.Editor.Utils;
        if (!elementChanged || !element) return false;
        if (!/^li|td|th$/.test(element.nodeName) &&
        utils.isNodeEmptyRecursive(element) &&
        !$telerik.$(element).find("ol,ul,table,h1,h2,h3,h4,h5,h6").length) {
            return true;
        }
        return false;
    }
</script>
</body>
</html>

When the page loads, switch to HTML mode, enter: <p> <h2></h2> <h2></h2> </p>

switch to Design mode, then switch back to HTML mode

get the error: "Error while executing filter XHTML - TypeError: e is null"

Firebug reports a script error:

TypeError: a is undefined
   }a=a.replace(/<body\s*\/>/i,"<body></body>").trim();

We're on editor version: 2014.1.403.45

Can you provide a working solution to this problem?

Thanks,
Trevor.

Hello Trevor,

Thank you for the additional feedback.

Indeed, testing with the mentioned version the issue is still reproducible. The fix is intended to be used along with further improvements available since 2014.2.724.

I recommend, along with adding the workaround to additionally upgrade the version of the Telerik UI for ASP.NET AJAX suite to the latest one (2014.2.724).

The improvements done in this version are complex and cannot be isolated in a simple workaround.

Let me know if you have any further concerns.
