Try to use rendered by the name of the column you want Expand.

Example: 

<p:rowExpansion rendered="#{c.nomeColuna == 'Coluna A' or c.nomeColuna == 'Coluna B}">
     Teste 
</p:rowExpansion>

I believe this condition will resolve your case.

Friend's choice above and good too, if it were some detailing I would use so if the list is not empty it shows. 

<p:rowExpansion rendered="#{not empty lista.lstItems}">
    Teste 
</p:rowExpansio>
