[CDK] c:foreach in a cast component will result on a List<Object> instead of List<UIComponent> ---------------------------------------------------------------------------------------------- Key: RF-12230 URL: https://issues.jboss.org/browse/RF-12230 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: cdk Affects Versions: 4.2.1.Final Environment: All Reporter: Paul Dijou Labels: cdk, generated, richfaces, xp Fix For: 4.3.0.Milestone1 Look at the following code : {code:xml} <cdk:object type="javax.faces.component.UIComponent" name="prependFacet" value="#{component.getFacet('prepend')}"/> <c:choose> <c:when test="#{prependFacet.family eq 'javax.faces.Panel'}"> <c:forEach var="child" items="#{component.getFacet('prepend').getChildren()}"> {code} I'm using a {{<cdk:object>}} to assign my facet to a var. Then I make some test and finally, I want to iterate over the children of my facet. This will result on this Java code on the renderer : {code:java} UIComponent prependFacet = component.getFacet("prepend"); if (isEqual(prependFacet.getFamily(),"javax.faces.Panel")) { for (UIComponent child: component.getFacet("prepend").getChildren()) { {code} That's perfect! But now, since I have a var for my facet, why not using it in the {{<c:forEach>}}? Seems natural. So I change my code to : {code:xml} <cdk:object type="javax.faces.component.UIComponent" name="prependFacet" value="#{component.getFacet('prepend')}"/> <c:choose> <c:when test="#{prependFacet.family eq 'javax.faces.Panel'}"> <c:forEach var="child" items="#{prependFacet.getChildren()}"> {code} Only the last line is different from the previous one. What does the generated Java code looks like? That: {code:java} UIComponent prependFacet = component.getFacet("prepend"); if (isEqual(prependFacet.getFamily(),"javax.faces.Panel")) { for (Object child: prependFacet.getChildren()) { {code} Whaaaaat?! Why is it a "Object" in the "for" loop and not a "UIComponent" anymore? Of course, the component is now broken since I'm calling {{UIComponent}} methods inside the loop.
