[richfaces-issues] [JBoss JIRA] (RF-12491) Datatable model is accessed in tab panel which is not rendered using switch type "server"

Datatable model is accessed in tab panel which is not rendered using switch type "server" ----------------------------------------------------------------------------------------- Key: RF-12491 URL: https://issues.jboss.org/browse/RF-12491 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-panels-layout-themes Affects Versions: 4.2.0.Final, 4.2.2.Final Environment: Mojarra 2.1.20, JDK 1.6, JDK 1.7, Tomcat 7.0.x Reporter: Denis Pasek Labels: lazy-loaded Fix For: 5-Tracking Attachments: richfaces-visittree.zip, stacktrace-richfaces.png When a RichFaces Tab of a TabPanel contains a RichFaces DataTable the model of the DataTable is accessed even if the Tab is not rendered at all. Since the retrieval of the data table data might include costly database operations this is a serious performance issue. The issue seems to be related to the state saving of JSF: the methods are not called during encodeAll() but during state saving of view. My own analysis shows that AbstractTogglePanel visitTree() implementation visits all tab panels sub tree but not only the active one. Additionally it seems that the UIDataAdaptor wants to visit all rows of table even if it is not rendered as JSF state saving runs in RENDER_RESPONSE phase (see attached stacktrace).
