Issue using RadHtmlField control

[Raj]

Hi

I'm trying to use the RadHtmlField control on a custom SharePoint page layout. The field I'm wrapping is a multi line rich text field (and not a publishing html field) and this is a required field.

I can see the editor coming up and am able to format content.  However when I try to save, the page validation fails and it says you must specify a value for this required field though I've filled content. Here's the code

<Rad:RadHtmlField FieldName="DemoMessage"  runat="server" id="NoteField1" 
                DisableInputFieldLabel="true" DisplayWidth="100%"    
                ConfigFile="/_layouts/RadEditor/ConfigFile.xml"
                ToolsFile="/_layouts/RadEditor/ToolsFile.xml" />

Does the field control work only with publishing html field?

Thanks
