Re: Namespace sitemesh decorators? Namespace from freemarker result?

Dear Roland-from-last-week,

The normal ConfigDecoratorMapper does what you want.  Since namespaces in Struts look like a "path" in the URL, you can simply apply a decorator to the pattern for the namespace.  For example, in your decorators.xml, do:

    <decorator name="yournamespace" page="yournamespace-decorator.ftl">
        <pattern>/yournamespace/*</pattern>
    </decorator>

There is no need for your templates to declare their decorator using the meta tag and thus invoke the PageDecoratorMapper.

love,
alert roland

Should I write my own NamespaceDecoratorMapper extends AbstractDecoratorMapper?  How would the DecoratorMapper get access to the ServletActionContext?
