Question

I am using primefaces for not so long and Ive found that I cant use a <p:commandButton /> because it just can’t reach the method, the method is ok, I tried it out of the table (and the subtable) and it works perfectly there (everything is inside a form) , the problem is that I need the user to be able to select all the subtable, so, I thought maybe with a button that could be possible, but seems like subtable doesn’t allow that, any other way I can do this? or maybe I have to use another way for call my method from a subtable, anybody knows about it?

Thanks

some of my code

<h:form>
    <p:messages id="messages" showDetail="true" autoUpdate="true" closable="true" />  
    <p:dataTable id="case" var="ticket" value="#{CaseBean.selectedCase.tickets}">
        <p:columnGroup>
            <p:row>
                <p:column> Action:</p:column>
                <p:column>
                    <!-- This doesn't work, removed. -->
                    <p:commandButton value="Aprove" action="#{CaseBean.acept()}">
                    </p:commandButton>
                </p:column>
            </p:row>
        </p:columnGroup>

        <p:subTable var="detail" value="#{ticket.detail}">
            <f:facet name="header">
                Resume:
            </f:facet>
            <!-- some data... -->
            <p:column>
                <!-- doesn't work either -->
                <p:commandButton value="Aprove" action="#{CaseBean.aceptTicket()}">
                </p:commandButton>
            </p:column>
<!-- show my data -->

The table works perfectly, it shows all the data, the log files doesn’t show any error, so, when I tried to write my commandButton out of the table it worked perfectly, if I cant write it inside a subtable its ok, but , how could I write it in the table? it doesn’t show up there either.

you welcome 🙂
But if i was you I wouldn’t use subtables, Ill think for another solution..maybe Ill do it this way, ill use two different data tables, the first contains the parent list and the second one contains the child list elements, and every selection made triggers an update of the second table…I tried it on my IDE and it works just fine

<h:form id="form">
<p:dataTable var="cas" value="#{beanCase.myListOfCase}"
    selection="#{beanCase.selectedCase}" rowKey="#{cas.idCase}"
    selectionMode="single">
    <p:ajax event="rowSelect" update=":form:TicketTable" />
    <p:column headerText="Id Case">
        <h:outputText value="#{cas.idCase}" />
    </p:column>
    <p:column headerText="Case Name ">
        <h:outputText value="#{cas.caseName}" />
    </p:column>
    <p:column headerText="Case Detail">
        <h:outputText value="#{cas.caseDetail}" />
    </p:column>
    <p:column headerText="Action">
        <p:commandButton value="Accept Case" update=":form:TicketTable"></p:commandButton>
    </p:column>
</p:dataTable>
<p:dataTable id="TicketTable" var="ticket"
    value="#{beanCase.selectedCase.tickets}">
    <p:column headerText="Ticket Number">
        <h:outputText value="#{ticket.idTicket}" />
    </p:column>
    <p:column headerText="Ticket Details">
        <h:outputText value="#{ticket.labelTicket}" />
    </p:column>
    <p:column headerText="show">
        <h:outputText value="#{ticket.show}" />
    </p:column>
    <p:column headerText="this show is brought to you by">
        <h:outputText value="#{ticket.sponsor}" />
    </p:column>
    <p:column headerText="Make a Reservation">
        <p:commandButton value="Buy" action="#{beanCase.buyTicket()}">
            <f:setPropertyActionListener value="#{ticket}"
                target="#{beanCase.selectedTicket}" />
        </p:commandButton>
    </p:column>
</p:dataTable>

before that you must create the data model classes for the Case and ticket

public class CaseDataModel extends ListDataModel<Case> implements
    SelectableDataModel<Case> {
CaseDAO caseDAO = new CaseDAO();

public CaseDataModel() {
}

public CaseDataModel(List<Case> cases) {
    super(cases);
}

@Override
public Case getRowData(String arg0) {
    List<Case> listOfMyObjet = (List<Case>) caseDAO.findAll();
    for (Case obj : listOfMyObjet) {
        if (String.valueOf(obj.getIdCase()).equals(arg0))
            ;
        return obj;
    }
    return null;
}

@Override
public String getRowKey(Case arg0) {
    return String.valueOf(arg0.getIdCase());
}

}
