<p:dialog> with <p:dataTable>

[usman]

Hello, i am facing a problem that whenever i use datatable inside a dialog then any call to my backing-bean actionListener is throwing an exception.
Exception is:
com.sun.faces.lifecycle.ApplyRequestValuesPhase execute

java.lang.IllegalArgumentException: -1

but when i remove the dataTable from the dialog then it is ok. Code for dialog is:

<p:dialog modal="false" id="allMachinesDialog" widgetVar="allMachinesPopUp" effect="fade" draggable="true" close="true" width="700" fixedCenter="true"
style="padding: 20px;" visible="false" header="All Machine(s)">

<p:dataTable id="dtAllMachinesPopUp" value="#{ManageAssignServerBean.allMachinesListDataModel}"
var="machine">

<p:column>
<f:facet name="header">
<h:outputText value="Name" />
</f:facet>
<h:outputText value="#{machine.name}" />
</p:column>

<p:column>
<f:facet name="header">
<h:outputText value="IP" />
</f:facet>
<h:outputText value="#{machine.ip}" />
</p:column>

<p:column>
<f:facet name="header">
<h:outputText value="Type" />
</f:facet>
<h:outputText value="#{machine.type}" />
</p:column>

<p:column>
<f:facet name="header">
<h:outputText value="Type" />
</f:facet>
<h:outputText value="#{machine.teamAssigned}" />
</p:column>


</p:dataTable>

</p:dialog>

Please help me out of this problem.
