Unable to view all the datasources in JBoss EAP 6.4 management console

Issue

• Unable to view all the datasources in JBoss Admin Console. We have created around 15 datasources in jboss . But when we check the number of datasources in Jboss Admin console only 5 datasources are visible. Please let us know if there is any setting that needs to be enabled to view the all the datasources.
• We would like to test all the XA datasource configurations using test connection through web console. We defined 6 XA datasources with enabled=true. We saw all of them bound to the JNDI tree in the server log and the web console configuration tab as well. However, only 5 of them showed up in the runtime tab of the XA datasource so we could not test the missing one.
