I like these solutions, but, I wonder if we should actually encode some of
this behavior as part of the DRI forms in the long run? I often wonder why
the Manakin project didn't embrace the Cocoon Forms... The strategy is
similar to what Tim has done...
<map:match pattern="viewform-*">
<map:generate type="jx" src="pages/{1}.xml"/>
* <map:transform type="browser-update"/>
* <map:transform type="i18n"/>
<map:transform src="resources/forms-styling.xsl"/>
<map:transform type="i18n">
* <map:select type="ajax-request">
<map:when test="true">
<map:serialize type="xml"/>
</map:when>
<map:otherwise>
<map:serialize type="html"/>
</map:otherwise>
</map:select>
*</map:match>
See for more ideas...
Previous version of Cocoon AJAX (for reference) *
http://cocoon*.apache.org/2.1/userdocs/*ajax*.html
Cocoon 2.2 Forms Block
http://cocoon.apache.org/2.2/blocks/forms/1.0/489_1_1.html
Cocoon 2.2 AJAX Block (Dojo based)
http://cocoon.apache.org/2.2/blocks/ajax/1.0/1350_1_1.html
I think the basic model would be to Map DRI Widgets to JXTemplates or CForm
Widgets and add a level to the transformation pipeline as Tim has done to
support those tools doing the heavy lifting of inserting the javascript
actions, rather than creating some that is custom to the DSpace comunity...
