Andrey Zhemoytuk created RF-13111: ------------------------------------- Summary: Data Iteration components evaluate value on postback even if not rendered when partial state saving is turned off Key: RF-13111 URL: https://issues.jboss.org/browse/RF-13111 Project: RichFaces Issue Type: Bug Security Level: Public (Everyone can see) Components: component-tables Affects Versions: 4.0.0.Final, 4.1.0.Milestone2 Environment: Fedora 15, Glassfish 3.1.1, CDI (Weld) Reporter: Andrey Zhemoytuk Assignee: Brian Leathem Fix For: 4.3.0.M3 In Richfaces 4 both datatable and extendedDatatable evaluate the value attribute even when rendered is set to false, even though it is not necessary. This makes it hard to achieve performance by trimming parts of the view tree. The built-in h:dataTable behaves correctly in that case. To reproduce simply try this snipplet: {code:xml} <h:form> <rich:dataTable value="#{myBean.property}" rendered="false"> </rich:dataTable> </h:form> {code} Side note: The reason I'm posting this is, that i want to embed a rich:dataTable in a ajax loaded rich:togglePanelItem which is loaded on demand. Probably fixing the "render" problem will also make the dataTable lazy-loadable when switching to the corresponding togglePanelItem. I hope this is no duplicate, I only found RichFaces 3 issues mentioning this problem. -- This message is automatically generated by JIRA.
