SelectedPages doesn't seem to switch context

[particleandparcel]

Hi Dan,

I've got a mt:SelectedPages container in a template that refuses to build, no matter what I try. MT always squawks that there's a context problem. I've got version 2.2.3 installed, I was hoping this resolved my issue. Here's a fragment of the template in question:

      <mt:IfNonEmpty tag="PageDataSelectedcontentitems">
      <!-- Begin featurettes -->
      <mt:SelectedPages basename="selectedcontentitems_new">
      <!-- Featurette: <mt:PageTitle /> -->
      <hr class="featurette-divider" id="<mt:PageBasename />">

      <div class="row featurette">
        <div class="col-md-7">
          <h2 class="featurette-heading"><mt:PageTitle /> <span class="text-muted"><mt:PageDataSubheadline /></span></h2>
          <p class="lead"><mt:PageBody /></p>
        </div>
        <div class="col-md-5">
          <img class="featurette-image center-block" src="<mt:PageDataSelectedmainimagethumbnail />" height="400" width="400">
        </div>
      </div>
      </mt:SelectedPages>
      </mt:IfNonEmpty>

The error is quite specific:

An error occurred publishing page '(PAGE TITLE)': Publish error in template 'Page': Error in <mtIfNonEmpty> tag: Error in <mtSelectedPages> tag: Error in <mtPageTitle> tag: You used an 'mtPageTitle' tag outside of the context of a page; Perhaps you mistakenly placed it outside of a 'MTPages' container tag?

Any advice would be appreciated.
