Look at the jwc and class file for the Any component. Tapestry hooks
up the following parameter with the value of the tag name in the
template...
<parameter name="templateTag" type="java.lang.String" direction="auto"
required="no" default-value="null">
<description>
The tag used to add this component in a template.
</description>
</parameter>
Looking at BaseComponentTemplateLoader.addTemplateBindings(IComponent
component, OpenToken token), the tag name is hooked up in this magical
way if and only if (from the source code comment)....
// if the component defines a templateTag parameter and
// there is no established binding for that parameter,
// add a static binding carrying the template tag
So, if you paste the above parameter declaration into your component
and ***add no accessors into the java file**, the value will be hooked
up.
Ok, how do you get at the value then in the java code? Again look at
the jwc file for Any, there is another parameter, element, which takes
as it's default value the value attached to templateTag, and element
has an abstract accessor getElement() in Any.java.
Just use the two parameters in Any as a pattern and you can have
access to the info you need.
