PartialViewContext#getRenderIds() implementation returns empty set ------------------------------------------------------------------ Key: RF-11112 URL: https://issues.jboss.org/browse/RF-11112 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-a4j-core Affects Versions: 4.0.0.Final Environment: Win7 x64, Eclipse Helios SR2, JBoss AS 6.0.0 Final, RF 4.0.0 Final. Reporter: Bauke Scholtz Assignee: Brian Leathem Labels: jsf Fix For: 5-Tracking During invoke action phase we would like to retrieve a list of partial render IDs for some specific preprocessing (resetting submitted values for the case they're embedded in another form). Those IDs are normally available by {{PartialViewContext#getRenderIds()}}. {code} PartialViewContext partialViewContext = FacesContext.getCurrentInstance().getPartialViewContext(); Collection<String> renderIds = partialViewContext.getRenderIds(); {code} This works fine in combination with standard JSF components, such as {{<h:commandLink><f:ajax render="foo"/></h:commandLink>}} However, when a RichFaces/A4J command component is been used, such as {{<a4j:commandLink render="foo" />}}, an empty collection is been returned instead. Debugging learns that the {{ExtendedPartialViewContextImpl}} implementation stores them in {{componentRenderIds}} instead of {{renderIds}} and never returns it on {{getRenderIds()}} method. The {{ExtendedPartialViewContextImpl}} also doesn't seem to use {{renderIds}} in a sensible manner anywhere else. I believe that {{componentRenderIds}} really has to be {{renderIds}} instead. As far now, we workarounded this by accessing the {{componentRenderIds}} field using reflection. {code} Collection<String> renderIds = partialViewContext.getRenderIds(); if (renderIds.isEmpty() && partialViewContext instanceof ExtendedPartialViewContextImpl) { try { Field componentRenderIds = ExtendedPartialViewContextImpl.class.getDeclaredField("componentRenderIds"); componentRenderIds.setAccessible(true); renderIds = (Collection<String>) componentRenderIds.get(partialViewContext); } catch (Exception e) { // Handle. } } {code} However, this introduced a nasty dependency in our code.
