Tomahawk: dataTable - DetailToggle (Target Unreachable)

["Nahrwold, Helge" <He...@LP-GMBH.com>]

Hello,

i want to use sublevel tables in my dataTable but I get exceptions ...

Now I have a dataTable like this:
----
<t:dataTable id="auftragTable" var="auftragKopf"
value="#{dispoAuftraege.auftragKoepfe}" preserveDataModel="true"
varDetailToggler="detailToggler">
	<h:column>
		<f:facet name="header">
			&nbsp;
		</f:facet>
			               
		<h:commandLink
rendered="#{detailToggler.currentDetailExpanded}"
action="#{detailToggler.toggleDetail}">
			<h:graphicImage url="images/minusButton.gif"
border="0" />
	      </h:commandLink>
		<h:commandLink
rendered="#{!detailToggler.currentDetailExpanded}"
action="#{detailToggler.toggleDetail}">
			<h:graphicImage url="images/plusButton.gif"
border="0" />
		</h:commandLink>  
	</h:column>

	...

	<f:facet name="detailStamp">
		<t:dataTable id="positionTable" var="position"
value="#{currentCountry.auftragpositionen}" preserveDataModel="false">
			<h:column>
				<f:facet name="header">
					Bezeichnung
				</f:facet>
				<h:outputText
value="#{position.artikelBezeichnung}" />
			</h:column>
		</t:dataTable> 
	</f:facet>
</t:dataTable>
----

Ok, the table was generated without any problems. When I klick on a + Button
in any row there come the followed exception:
