Allow RichFaces to bring new CSS/JS resources into the page after AJAX request ------------------------------------------------------------------------------ Key: RF-12270 URL: https://issues.jboss.org/browse/RF-12270 Project: RichFaces Issue Type: Feature Request Security Level: Public(Everyone can see) Components: core, resource handling Affects Versions: 4.2.2.Final Reporter: Tomasz Kurpios Fix For: 5-Tracking Quoting the extract from official documentation (3.5 Restrictions): ??JSF 2 does not allow resources such as JavaScript or Cascading Style Sheets (CSS) to be added if the element requiring the resource is not initially present in the JSF tree. As such, components added to the tree via Ajax must have any required resources already loaded. In RichFaces, any components added to the JSF tree should have components with corresponding resources included on the main page initially. To facilitate this, components can use the rendered="false" setting to not be rendered on the page.?? Setting rendered="false" is OK when components are in the tree. However, if there are lots of components on a single view, for performance reasons some parts might be excluded by means of <c:if> or <c:choose> tags. That's at least what could be done in 3.3.3. It worked fine back then. However, the JSF2 AJAX mechanism does not support this feature. This makes usage of aforementioned tags impossible in some cases.
