Apache Tiles: abstract definition extending another abstract one

I'm using Tiles 2.2 and I'd like to reuse a single JSP to display different messages. Messages have to be defined inside Tiles configuration file.

The following example is my approach: base is the base abstract definition all other definitions extend, while display would be an another abstract definition, used as a template for displaying messages. page1 and page2 are two final pages examples, each one displays a different message.

<definition name="base" template="layout.jspx"/>

<definition name="display" extends="base">
        <put-attribute name="body" value="display.jspx"/>
</definition>

<definition name="page1" extends="display">
        <put-attribute name="message" value="This is one message!"/>
</definition>

<definition name="page2" extends="display">
        <put-attribute name="message" value="This is another message!"/>
</definition>

display.jspx would have something like this inside:

<tiles:useAttribute name="message"/>
Message: ${message}

But I couldn't make it to work, because when opening page1 or page2 I get an exception saying message attribute is null.

Is there an easy way to set up something like this, without modifying base template and definition?

Thanks in advance

Probably too late, but I believe you need to add cascade="true" to your put-attribute elements for name="message".
