Melloware commented on MYFACES-4560:
------------------------------------
Yes and that gets completely ignored and the underlying SelecItem `itemLabel`
is used so the XHMTL there is completely ignored.
> Faces Issue #1791 SelectItems rendering
> ---------------------------------------
>
> Key: MYFACES-4560
> URL: https://issues.apache.org/jira/browse/MYFACES-4560
> Project: MyFaces Core
> Issue Type: Improvement
> Affects Versions: 2.3.10, 2.3-next-M7, 3.0.2, 4.0.0-RC4
> Reporter: Melloware
> Priority: Major
>
> See; [https://github.com/jakartaee/faces/issues/1791]
>
> The component should render the itemLabel as instructed by the provided EL,
> even if the backed data type is SelectItem. The default rendering should only
> be done when the attribute is missing.
> Example:
> {code:java}
> <h:form id="frmTest">
> <p:selectOneMenu id="test1">
> <f:selectItems value="#{testView.items}" var="i"
> itemValue="#{i.value}" itemLabel="#{i.value} - #{i.label}" />
> </p:selectOneMenu>
> <p:selectOneMenu id="test2">
> <f:selectItems value="#{testView.items2}" var="i"
> itemValue="#{i.key}" itemLabel="#{i.key} - #{i.value}" />
> </p:selectOneMenu>
> <p:selectOneMenu id="test3">
> <f:selectItems value="#{testView.items}" />
> </p:selectOneMenu>
> <p:selectOneMenu id="test4">
> <f:selectItems value="#{testView.items2}" />
> </p:selectOneMenu>
> </h:form>{code}
> The issue is `id="test1"` the user is expecting it to render
> `itemLabel="#\{i.key} - #\{i.value}"` but it is ignored and just the
> underlying Java SelectItem value is rendered.
