Alex Savitsky commented on JBSEAM-2224:


What files were changed as part of this fix? I'lll just grab these from CVS into into my project (overriding the JAR) and test it that way. Definitely would take less time that to figure out how to build full JARs...

> The resultList of an EntityQuery gets reset to contain all nulls after several AJAX interactions. I'm not sure whether it's Seam or RichFaces that causes the problem (I'm still investigating the cause), but it's bound to be one or the other, because a) it's the EntityQuery that gets reset and b) it only happens when one or more Ajax-enabled RichFaces controls are present on the page. The attached test case uses datascroller & data table, but I was able to observe it with other controls, such as suggestion box.
> Steps to reproduce:
> 1. Put all libraries listed in WEB-INF/lib/libs.txt in WEB-INF/lib (essentially Seam 2.0.0 GA, RichFaces 3.1.2 GA, Hibernate EM 3.3.1 GA, Facelets 1.1.14, Sun JSF RI 1.2.05, plus supporting libs). I didn't put them into WAR, as this makes it >10M big.
> 2. Deploy the WAR and access it at http://hostname/TestCase/index.jsf
> 3. Activate the data scroller TWICE IN A ROW (important) - e.g., press "next page" twice
> 4. Check the contents of the dropdown (just to know what's there normally)
> 5. Select an item in the data table
> 6. Check the contents of the dropdown. All entries are empty now!
