Leonardo Uribe commented on MYFACES-3853:
-----------------------------------------
I have checked the demo and there is a bug in the SectionUniqueIdCounter. Under
this combination:
System.out.println(counter.generateUniqueId());
System.out.println(counter.generateUniqueId());
System.out.println(counter.startUniqueIdSection("X"));
System.out.println(counter.generateUniqueId());
System.out.println(counter.generateUniqueId());
System.out.println(counter.startUniqueIdSection());
System.out.println(counter.generateUniqueId());
System.out.println(counter.generateUniqueId());
It generates:
1
2
3_X
3_X_1
3_X_2
3_3
3_3_1
3_3_2
But it should be:
1
2
3_X
3_X_1
3_X_2
3_X_3
3_X_3_1
3_X_3_2
> ui:include not working inside c:forEach
> ---------------------------------------
>
> Key: MYFACES-3853
> URL: https://issues.apache.org/jira/browse/MYFACES-3853
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.2.0
> Reporter: Gonçalo Manuel Cruchinho
> Priority: Critical
>
> Using ui:include inside a c:forEach cases a duplicate id error. This only
> happens if there is at least a second element to iterate.
> The exception is the following: java.lang.IllegalStateException: Client-id :
> <clientId> is duplicated in the faces tree.
> Below there's an example of a test case that replicates the problem.
> Test Case
> Myfaces22ForEach.java
> @ManagedBean(name = "myfaces22foreach")
> @SessionScoped
> public class Myfaces22ForEach {
> private List<String> pageList;
> public List<String> getPageList() {
> if (pageList == null) {
> pageList = new ArrayList<String>();
> pageList.add("page1.xhtml");
> pageList.add("page2.xhtml");
> }
> return pageList;
> }
> public void setPageList(List<String> pageList) {
> this.pageList = pageList;
> }
> }
