New Revision: 473102
URL: http://svn.apache.org/viewvc?view=rev&rev=473102
Log:
Added an extra hook in the Clay commons chains flow that builds the sub
component tree. You an now register handlers in the "clayCustomization"
catalog to address specialized components.
For example, if you had a component that required a unique method binding you
could register a commons chain handler to address the need (SHALE-326).
An example chains config snippet:
<catalog name="clayCustomization">
<!-- custom method binding attriubte handler -->
<chain name="attributeChangeListener">
<command
className="org.apache.shale.clay.component.chain.trinidad.AttributeChangeListenerCommand"/>
</chain>
<!-- custom html namespaces-->
<chain name="http://myfaces.apache.org/trinidad";>
<command
className="org.apache.shale.clay.parser.builder.chain.JsfDefaultBuilderRule"
prefix="tr" />
</chain>
<chain name="http://myfaces.apache.org/trinidad/html";>
<command
className="org.apache.shale.clay.parser.builder.chain.JsfDefaultBuilderRule"
prefix="trh" />
</chain>
</catalog>
