I am trying to use TinyMCE on the fronted of my website but i have problem when i make post request which dosent pass custom validation and than I return CurrentUmbracoPage whcih ruin my encoded text in RTE.

This is how it looks before post request:

And after post request which Return CurrentUmbracoPage:

This is my model:

 [UIHint("tinymce_jquery_full"), AllowHtml]
 public string Text { get; set; }

This is how i render text in RTE:

EditModel.TextEn = HttpUtility.HtmlDecode(newsItem.Value<string>("text", "en-US"));

It would solve my problem if i could have model property of type IHtmlString, but cant get it work.
