Primefaces dataTable cannot edit after tab changed - primefaces

Question

Originally I used an editable dataTable, and it worked fine.
Then I put the dataTable in a dymanic tabView's tabs, then in the first rendered tab workes fine, but after I change tab, I cannot edit cells.
PrimeFaces version: 6.0
<p:tabView value="#{tippingViewBean.rounds}" var="round" dynamic="true">
<p:tab title="#{round}.">
<p:dataTable id="tippingTable#{round}" rowIndexVar="rowId" editable="true" editMode="cell"
widgetVar="cellTips"
var="userTip" value="#{tippingViewBean.getUserTips(round)}"
resizableColumns="true">
<p:ajax event="cellEdit" listener="#{tippingViewBean.addTip(userTip)}"/>
<p:column headerText="Kezdés">
<h:outputText value="#{userTip.schedule.date}"/>
</p:column>
<p:column headerText="Hazai Csapat">
<h:outputText value="#{userTip.schedule.homeTeam.name}"/>
</p:column>
<p:column headerText="Vendég Cspat">
<h:outputText value="#{userTip.schedule.awayTeam.name}"/>
</p:column>
<p:column headerText="Győztes">
<p:cellEditor>
<f:facet name="output"><h:outputText value="#{userTip.winnerTip}"/></f:facet>
<f:facet name="input">
<p:selectOneMenu id="winnerTipInput#{round}"
disabled="#{tippingViewBean.tipIsClosed(userTip)}"
value="#{tippingViewBean.winnerTip}" style="width: 100%">
<f:selectItems value="#{tippingViewBean.winnerTipForSelection}" var="selectItem"
itemLabel="#{selectItem}" itemValue="#{selectItem}"/>
</p:selectOneMenu>
</f:facet>
</p:cellEditor>
</p:column>
<p:column headerText="2,5 Gól alatt/felett">
<p:cellEditor>
<f:facet name="output"><h:outputText value="#{userTip.twoAndHalfTip}"/></f:facet>
<f:facet name="input">
<p:selectOneMenu id="goalsTipInput#{round}"
disabled="#{tippingViewBean.tipIsClosed(userTip)}"
value="#{tippingViewBean.goalsTip}" style="width: 100%">
<f:selectItems value="#{tippingViewBean.goalsTipForSelection}" var="goalsSelectItem"
itemLabel="#{goalsSelectItem}" itemValue="#{goalsSelectItem}"/>
</p:selectOneMenu>
</f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
</p:tab>
</p:tabView>
What I'm doing wrong?

Answer 1

Ok, I found the answer.
I changed the dataTable's widgetVar to unique ( cellTips#{round} ), and it works.
