Replied to wrong thread so aplologolies for duplicate##
All,
I have woodstock tables rendering ok in a seam ajax4jsf environment but actions not working. I have the javascript / dojo includes ..
From firebug look like events are being triggered ok but table not updating, even basic sort functionality.
Note I am backing by Objectdataprovider per Dans blog /example
Any quick pointers ?
Rgds,
Padraig.

This msg was forwarded to me today (I haven't been monitoring this alias) .
I just subscribed. If there's something not answered here, please let
me know.
Here's the Data Provider documentation:
http://developers.sun.com/jscreator/reference/fi/2/data-providers.html
http://developers.sun.com/docs/jscreator/apis/dataprovider/index.html
http://developers.sun.com/jscreator/learning/tutorials/2/dataproviders.html

DataProviders wrap data access.. CachedRowSetDataProvider wraps and can
cache data but requires a JDBC rowset. Queries are done in SQL.
Transactions are managed by the user.
JPA is a better option, but Visual Web doesn't provide drag and drop
capability yet.
There is a What's new in Visual Web webinar the explains how to use JPA
http://sunmeetings.webex.com/sunmeetings/onstage/g.php?AT=VR&RecordingID=300278377
and some blogs
