[richfaces-issues] [JBoss JIRA] Commented: (RF-8223) ExtendedDataTable duplicate Id exception

[ https://jira.jboss.org/jira/browse/RF-8223?page=com.atlassian.jira.plugin... ] Alex Kolonitsky commented on RF-8223: ------------------------------------- The problem explanation: 1) when jsf-facelets is rendering page, it sets id="j_id3" to the column using root.createUniqueId() ComponentHandler.apply(...) { ... UIViewRoot root = ComponentSupport.getViewRoot(ctx, parent); if (root != null) { String uid = root.createUniqueId(); c.setId(uid); } ... } 2) ExtendedDataTable has an inner ContextMenu component, and when ExtendedDataTable is rendering the ContextMenu they invoke clientId for ContextMenu AbstractExtendedTableRenderer.encodeTableMenu(...) { ... String menuId = menuRenderer.renderMenu(context, table, col); ... } 3) but for jsf 2.0 the getClientId() method was overriden from UIComponentBase.getClientId(FacesContext context) { ... setId(context.getViewRoot().createUniqueId()); ... } to UIComponentBase.getClientId(FacesContext context) { ... String generatedId; if (null != namingContainerAncestor && namingContainerAncestor instanceof UniqueIdVendor) { generatedId = ((UniqueIdVendor)namingContainerAncestor).createUniqueId(context, null); } else { generatedId = context.getViewRoot().createUniqueId(); } setId(generatedId); ... } 4) and now UIData (and UIExtendedDataTable) is a UniqueIdVendor. So for ContextMenu we have UniqueId only in UIExtendedDataTable but this id conflicts with components id which is generated by ComponentHandler -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
