Resolution: Done
> [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
> Assignee: Lukáš Fryč
> Labels: cdk, generated, richfaces
> 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.
