Folks,
I have a small problem with nested templates in Prado at the moment. What I have is:

MainLayout.tpl:
Code:
<html>
<com:THead />
<body>
<com:TForm>
<com:TContentPlaceHolder ID="ScreenTitle"/>
<com:TContentPlaceHolder ID="Titlebar" />
<com:TContentPlaceHolder ID="Menu" />
<com:TContentPlaceHolder ID="Content" />
</com:TForm>
</body>
</html>

StudentView.tpl:
Code:
<%@ MasterClass="Application.layouts.MainLayout" %>
<com:TContent ID="Content">
<com:TContentPlaceHolder ID="placetitlecontent"/>
<com:TContentPlaceHolder ID="subplacescontent"/>
<com:TContentPlaceHolder ID="episodescontent"/>
<com:TContentPlaceHolder ID="resourcescontent"/>
</com:TContent>

Home.page:
Code:
<com:TContent ID="Titlebar">
<com:TBulletedList ID="Breadcrumb"/>
</com:TContent>

<com:TContent ID="Menu">
<com:TBulletedList ID="menulist" />
</com:TContent>

<com:TContent ID="placetitlecontent">
<com:TLabel ID="contenttext" />
<com:TBulletedList ID="exits" DisplayMode="LinkButton" />
</com:TContent>

config.xml:
Code:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <pages MasterClass="Application.layouts.StudentView" />
</configuration>

According to all the tutorials, this should work, but what I get is a TConfigurationException:
Description
TContent 'Titlebar' does not have a matching TContentPlaceHolder.
Source File
/www/prado/3.1.1.r2290/framework/Web/UI/TTemplateControl.php (212)


Any ideas what could be causing this?

This usage is not supported by design. The matching of TContent and TContentPlaceHolder must be between direct master class and content class.

Oh bother.
So it's not so much nested templates then as it is loosely linked templates.
Oh well.

Thanks as well to aztech, by the way, who answered a panicy PM about this topic as well and who suggested this to solve the problem (it does, btw):

StudentView.tpl:
Code:
<%@ MasterClass="Application.layouts.MainLayout" %>
<com:TContent ID="Content">
<com:TContentPlaceHolder ID="placetitlecontent"/>
<com:TContentPlaceHolder ID="subplacescontent"/>
<com:TContentPlaceHolder ID="episodescontent"/>
<com:TContentPlaceHolder ID="resourcescontent"/>
</com:TContent>
<com:TContent ID="ScreenTitle">
  <com:TContentPlaceHolder ID="ScreenTitleDeep"/>
</com:TContent>
<com:TContent ID="TitleBar">
  <com:TContentPlaceHolder ID="TitleBarDeep"/>
</com:TContent>
<com:TContent ID="Menu">
  <com:TContentPlaceHolder ID="MenuDeep"/>
</com:TContent>
<com:TContent ID="Content">
  <com:TContentPlaceHolder ID="ContentDeep"/>
</com:TContent>
