primefaces datatable don't refresh correctly with column toggler - jsf

Question

Users just noticed a big bug in my datatable. When you use a datatable and a column toggler, unselecting a column just shift some rows, but it goes wrong when some cells are empty.
So i tried to refresh my data table with
`<p:columnToggler datasource="datalist" trigger="toggler">
<p:ajax event="toggle" update="datalist"/>
</p:columnToggler>`
but it goes wrong with :
`<p:columns value="#{consultationView.columns}" var="column" columnIndexVar="colIndex"
visible="#{column.property.matches('Z06|Z07|Z09')}" >`
Because if i unselected a visible column it makes it visible again...
here is the full datatable :
`
<f:facet name="header">
<p:commandButton process="listFDP" icon="ui-icon-file-pdf" value="Editer les fiches de paie" action="#{consultationView.printPaieAgent()}" escape="false" ajax="false" onclick="this.form.target='_blank'" />
<p:commandButton id="toggler" type="button" value="Colonnes"
style="float:right" icon="ui-icon-calculator" />
<p:columnToggler datasource="datalist" trigger="toggler">
<p:ajax event="toggle" update="datalist"/>
</p:columnToggler>
</f:facet>
<p:column selectionMode="multiple" style="width:16px;text-align:center" exportable="false" toggleable="false" />
<p:column style="width:60px;text-align:left"
sortBy="#{row.gestion.datePaiement}" headerText="Pér. Paie" groupRow="true" sortOrder="ASCENDING" >
<h:outputText value="#{row.gestion.datePaiement}">
<f:converter binding="#{dateConverterMoisAnnee}" />
</h:outputText>
</p:column>
<p:column style="width:60px;text-align:left"
sortBy="#{row.gestion.dateOrigine}" headerText="Pér. Origine">
<h:outputText value="#{row.gestion.dateOrigine}">
<f:converter binding="#{dateConverterMoisAnnee}" />
</h:outputText>
</p:column>
<p:column headerText="N° cont." style="width:25px;text-align:center;white-space:pre-line;">
<h:outputText value="#{row.gestion.matricule.substring(10)}" />
</p:column>
<p:column headerText="Statut" style="width:150px;text-align:left;white-space:pre-line;" sortBy="#{row.statut}">
<h:outputText value="#{row.statut}" />
</p:column>
<p:columns value="#{consultationView.columns}" var="column" columnIndexVar="colIndex"
visible="#{column.property.matches('Z06|Z07|Z09')}" >
<f:facet name="header">
<h:outputText value="#{column.header}" />
</f:facet>
<h:outputText value="#{row.getRubValue(column.property)}" />
</p:columns>
</p:dataTable>`
