Inheriting a specification

[Jamis Buck <jg...@email.byu.edu>]

I've got a situation where I need to extend the Form component (to add 
another hidden field).  I know I need to create a new .jwc file for this 
component, but I want it to also have all the parameters of its 
ancestor.  Is the only way to do this to explicitly copy the contents of 
org.apache.tapestry.form.Form.jwc into my NewForm.jwc file?  Or is there 
a cleaner way of doing this?

You can't inherit, but you can wrap and pass through parameters. Use
<inherited-binding>

<component-specification  allow-body="yes" allow-informal-parameters="yes"
                          class="mypackage.MyClass">
    <parameter name="data" type="java.lang.Object" direction="in"
required="yes" />

    <component id="tableElement" type="contrib:Table"
inherit-informal-parameters="yes">
        <inherited-binding name="source" parameter-name="data"/
    </component>

</component>
