adding a custom tag to the PopupPanel widget

[NatashaManzuiga]

Hi, I'm trying to add a custom tag to the PopupPanel ...... the part coloured in black

<div class="esriPopup" style="width: 100%;">
  <div class="actionsPane" data-dojo-attach-point="actionsPaneDiv" style="padding-bottom: 8px;">
    <div class="actionList" data-dojo-attach-point="actionsListDiv">
    </div>
  </div>
  <div data-dojo-type="dijit/layout/TabContainer"  id="tabContainer"  data-dojo-attach-point="tabContainerDiv">
    <div data-dojo-type="dijit/layout/ContentPane" title="test" id="testTab" >
      <div id="delegatesDiv"></div>tab pane #1</div>
  </div>
</div>

But I'getting this error:
init.js:115 Error: dijit._WidgetsInTemplateMixin: parser returned unfilled promise (probably waiting for module auto-load), unsupported by _WidgetsInTemplateMixin.   Must pre-load all supporting widgets before instantiation.

Why? ... I'm using LaunchpadTheme.

Thanks,

Naty

Sounds like you did not add the tab container module to the widget.js define array
