Having both RichFaces 4.5 and 5.x taglibs in one JSF project malfunction components auto completion --------------------------------------------------------------------------------------------------- Key: JBIDE-16272 URL: https://issues.jboss.org/browse/JBIDE-16272 Project: Tools (JBoss Tools) Issue Type: Bug Components: jsf Affects Versions: 4.1.0.1.Final Reporter: Juraj Húska Assignee: Alexey Kazakov When I create new JSF project, where I add RichFaces libraries needed to create _RichFaces 4.5_ (a special version which should be some kind of bridge between RichFaces 4 and 5) application: * richfaces-5.0.0.Alpha2.jar * richfaces-components-a4j-4.5.0.Alpha1.jar * richfaces-components-rich-4.5.0.Alpha1.jar Then if you have all supported namespaces included, auto completion triggered e.g. on {{<a4j:}} will provides also non existing components, like {{<a4j:calendar}} (it should be {{<rich:calendar}} ) Please see steps to reproduce.
