Primefaces p:commandLink not working in p:datatTable

문제

i just don't get it...

Why p:commandLink not working? The page is refreshing but with the same amount of data in table. I'm supposing that controller is okay. Take a look.\

                            <p:column rendered="#{loginController.admin}">
                                <f:facet name="header">
                                    <h:outputText value="Administracja" />
                                </f:facet>
                                <h:form>
                                    <p:commandLink id="Remove" value="Remove" action="#{warningsController.remove(item.id)}" ajax="false" />
                                </h:form>
                            </p:column>
                        </p:dataTable>
                    </h:form>
                </f:view>
            </ui:define>
        </ui:composition>

    </body>
</html>

and controller:

public String remove(long a){
    //System.out.println(a);
    pf.remove(pf.find(a));
    return "Listsev.xhtml";
}

해결책

You have multiple h:forms cascaded/nested, that's invalid html. Unknown/wanted side effects can/may occur, maybe like you are experiencing right now. Get right if that inner h:form and try again.

In your remove method, pf is the list which you return by calling #{warningsController.warns}?
