        <p:column>
            <p:selectOneMenu value="#{bean.selectedObject}" id="idSelect" converter="objectConverter">
                <f:selectItems value="#{bean.objectsList}" var="varObject" itemLabel="#{varObject.label}" itemValue="#{varObject}" />

i overrode .ui-selectonemenu, .ui-selectonemenu-label to:

.ui-selectonemenu{
     width: 100% !important;
}
.ui-selectonemenu-label{
     width: 100% !important;
}
