> The following error occurs when a JSF component adding a resource is added in a JSTL tag handler:
> {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: /test.xhtml][Class: org.apache.myfaces.component.ComponentResourceContainer,Id: jakarta_faces_location_head][Class: jakarta.faces.component.UIOutput,Id: j_id__rd_5]}

> In our example, the resource that is apparently added to the component tree twice is _inputmask/inputmask.js_ of the _p:calendar_ component when using it in a {_}c:forEach{_}.
> The error only happens if _STRICT_JSF_2_FACELETS_COMPATIBILITY_ is enabled, but that is a requirement for our application. The error does not occur in Mojarra.
> I would appreciate you looking into this, as it is a pretty big problem for us. And before you ask: We're using c:forEach because in our application changing from c:forEach/c:if to ui:repeat/ui:fragment would result in an increase of components in the component tree by a factor of about 5 on some sites.
> I could copy and paste more of the code here, but I think it's easier to just look at the reproducer: [https://github.com/mkomko/primefaces-test/tree/inputmask-duplicateid]
> The error occurs when opening the dialog using the button and then clicking "Cancel".
> Thank you very much in advance!
