  ## t5/core/exception-frame

  Manages a special element used to present an HTML exception report from an Ajax request (where a non-markup response was expected, including a partial page render response).

      define ["t5/core/dom"], (dom) ->

        write = (container, content) ->
          iframe = (container.findFirst "iframe").element

- ¶

  See http://xkr.us/articles/dom/iframe-document/

          iframeDocument = iframe.contentWindow or iframe.contentDocument
          if iframeDocument.document
            iframeDocument = iframeDocument.document

- ¶

  Clear current content:

          iframeDocument.open()

- ¶

  Write new content:

          iframeDocument.write content
          iframeDocument.close()

        clear = ->
          container = @closest '.exception-container'
          container.remove()
          return false

        create = ->

          container = dom.create
            class: "exception-container"
            """
              <iframe> </iframe>
              <div>
                <button class="pull-right btn btn-primary">
                  <i class="icon-remove icon-white"></i>
                  Close
                </button>
              </div>
            """

          dom.body.append container.hide()

          container.on "click", "button", clear
          container

          return
