tab panel which does an <ui:include> to a page with a datatable and an associated datapaginator gave me grief by throwing exception when I pressed the refresh button in the browser on first entry to that tab. Tried giving manual IDs to all components:

[code]
<ice:dataPaginator
for="xxx"
id="pag"
paginator="true">
<f:facet name="first" id="firstfac">
<ice:outputText value="first" id="firstout"/>
</f:facet>
<f:facet name="last" id="lastfac">
<ice:outputText value="last" id="lastout"/>
</f:facet>
<f:facet name="next" id="nextfac">
<ice:outputText value="next" id="nextout"/>
</f:facet>
<f:facet name="previous" id="prevfac">
<ice:outputText value="previous" id="prevout"/>
</f:facet>
<f:facet name="fastforward" id="fastfwdfac">
<ice:outputText value="fastforward" id="fastfwdout"/>
</f:facet>
<f:facet name="fastrewind" id="fastrevfac">
<ice:outputText value="fastrewind" id="fastrevout"/>
</f:facet>
</ice:dataPaginator>
[/code]

and the interesting part of the stacktrace is

[code]

[/code]

which leads to the question: Is there a copypaste-bug in the ID generation code?
