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 ?

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 > >> I will take a more detailed read through it. >> >> Do you know if any work done on working with external entity managers >> / caches ? or is dataprovider intended as a entity manager and cache >> of sorts itself ? > > I don't know.

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 http://www.winstonprakash.com/articles/netbeans/JPADataBinding.html John Baker > > Dan > >> >> Rgds, >> Padraig. >> >> ----- Original Message ---- >> From: Dan Labrecque <Dan.Labrecque@Sun.COM> >> To: dev@woodstock.dev.java.net >> Sent: Monday, August 13, 2007 4:11:19 PM >> Subject: Re: Woodstock table with Seam ? >> >> Padraig Byrne wrote: >>> Current situation is I have seam, richfaces & facelets with entity beans generated by seamgen but I like functionality of woodstock table (& some other components), which uses dataprovider as backend for table as far as I can see. >>> >>> seam gen generates beans which extend entityQuery beans & which I can directly connect woodstock table & perform sort functionailty out of the box but when I want to add filtering etc all the example use helper classes which are based on dataprovider ( eg filtercriteria ) I am trying to get a detailed understanding of this table & dataproviders & compatibility with entity beans >>> >> >> Although the Woodstock table makes use of DataProvider, it is a >> separate jar created by the Netbeans Visual Web Pack >> <http://www.netbeans.org/products/visualweb> folks.
