JSF h:selectOneMenu weird stuff

Question

Hello, I'm a newbie.
I have a working ComboBox (selectOneMenu) in one panelGroup the contents of which are populated in .java file from a DB. (the code is not mine, it's a big project). The panelGroups are opened one at a time depending which menu is selected. I want the same combobox in the other panelGroup, so I copy the code
<h:selectOneMenu valueChangeListener="#{administration_analysis_report_user.changeAnalysisReport}" binding="#{administration_analysis_report_user.analysisReport}" onchange="submit();">
    <f:selectItems value="#{administration_analysis_report_user.analysisReportList}" />
</h:selectOneMenu>to other panelGroup, but it does not appear (does not generate any code).
Which can be the problem (i tried putting IDs, removing these bindings/actionListeners, but nothing helped). But as I rename selectOneMenu into selectManyListbox, the list appears.
Thanks for guidelines!

Thanks for a quick reply!
The problem is that I don't get the cloned (copy->pasted) comboBox (selectOneMenu) after I copy/paste the code. If i rewrite it into listbox, everything works fine even without altering .java code, which is not even the case here.
in an associated java file everyting is as you'd described:
private HtmlSelectOneMenu analysisReport; // + getter + setter
the only weird thing is that I cannot have this selectOneMenu working in another panelGroup. The weird thing to tell of all this is as if the original comboBox is somehow bound to the panelGroup it is in, and any copy/pastes to elsewhere stop it from working. But I cannot trace that bound anyhow.
Once again -- there's nothing to do with object type mismatches.
