Description of problem:
When I use Google Chrome (16) to search in the Servers inventory page with the following query: 'availability=up', an error is displayed: "Failed to load resource composite data": 

java.lang.RuntimeException:[1323873789909] javax.ejb.EJBException:java.lang.IllegalArgumentException: PageList was passed an empty collection but 'totalSize' was 3, PageControl[firstRow=25, size=50] -> java.lang.IllegalArgumentException:PageList was passed an empty collection but 'totalSize' was 3, PageControl[firstRow=25, size=50]

Version-Release number of selected component (if applicable):
JBoss Operations Network 3.0.0.GA
Fedora 16 X86_64 
OpenJDK 1.6.0_22 fedora-61.1.10.4.fc16-x86_64
Google Chrome: 16.0.912.63

How reproducible:
Setup a JON server and a JON agent, a PostgreSQL database and 2 JBoss EAP 5.1.2 nodes (I'm running a clustered setup of 2 nodes on my machine). Import the PostgreSQL and JBoss EAP resources in JON. Go to the Inventory tab, select 'Servers' and enter the query 'availability=up'.


Steps to Reproduce:
1. See above
  
Actual results:
Error message is displayed "Failed to load resource composite data"

Expected results:
List with available resources is displayed.

Additional info:
When I use Firefox 8.0 the error does not occur and the available resources are listed on the page like expected.
