-----------------------------------
I have now tested this using a custom MyFaces build, because we seem to have
the same problem. But we still get the following exception:
{code:java}
org.apache.myfaces.view.facelets.compiler.DuplicateIdException: Component with
duplicate id "j_id__rd_5" found. The first component is {Component-Path :
[Class: jakarta.faces.component.UIViewRoot,ViewId: /person.xhtml][Class:
org.apache.myfaces.component.ComponentResourceContainer,Id:
jakarta_faces_location_head][Class: jakarta.faces.component.UIOutput,Id:
j_id__rd_5]}

{code}
It happens under the following circumstances:
* Have a page with a composite component (not sure if that's necessary)
* Have a _c:forEach_ in the composite component
* Use a bean annotated with _org.omnifaces.cdi.ViewScoped_ on the page. This
results in faces.js and omnifaces.js being added to the HTML body (not head,
because it's too late for that).
* Have _STRICT_JSF_2_FACELETS_COMPATIBILITY_ enabled (not sure if that's
necessary either, but that's what we use)
* Have AJAX postbacks
Sadly, I wasn't able to reproduce it in an isolated environment (the
primefaces-test project) even though I rebuilt it there very very similarly. So
I understand if you can't follow up. But I just wanted to mention it.
We will now workaround it by switching back to
{_}jakarta.faces.view.ViewScoped{_}. We originally switched to OmniFaces in JSF
2.3 because of other problems, but these do not seem to be present anymore.
