I am trying to filter using a Select One Menu using PrimeFaces 6.1. But the menu does not drop down to show its values. It acts as if it is disabled. I have wrapped my datable with <h:form> and checked to see if the menu is populated in the browser inspect window.

Edit:

Here is the table:

        <h:form>

            <p:dataTable var="left" value="#{dataFilterView.leftGrid}"

                widgetVar="leftTable"

                filteredValue="#{dataFilterView.filteredLeftGrid}">

                <ui:debug />

                <p:column headerText="Project">

                    <h:outputText value="#{left.projectName}" />

                </p:column>

                <p:column headerText="Company">

                    <h:outputText value="#{left.companyName}" />

                </p:column>

                <p:column headerText="Location" filterBy="left.projectLocation">

                    <h:outputText value="#{left.projectLocation}" />

                </p:column>

                <p:column headerText="Request Name">

                    <h:outputText value="#{left.requestName}" />

                </p:column>

                <p:column headerText="Request Type" filterBy="#{left.requestType}"

                    filterMatchMode="exact">

                    <f:facet name="filter">

                        <p:selectOneMenu onchange="PF('leftTable').filter()"

                            style="width:70%; box-sizing: border-box;">

                            <f:selectItem itemLabel="Select One" itemValue="#{null}"

                                noSelectionOption="true" />

                            <f:selectItems

                                value="#{dataFilterView.uniqueRequestTypes.entrySet()}"

                                var="data" itemValue="#{data.key}" itemLabel="#{data.value}" />

                        </p:selectOneMenu>

                    </f:facet>

                    <h:outputText value="#{left.requestType}" />

                </p:column>

            </p:dataTable>

        </h:form>

The ManagedBean is:

@ManagedBean(name = "dataFilterView")

@SessionScoped

public class DataFilterView {



private String reqType;



private List<LeftGridBean> leftGrid;

private List<LeftGridBean> filteredLeftGrid;



private List<String> uniqueLocations;

private Map<String, String> uniqueRequestTypes;



@ManagedProperty("#{supplierRequestsService}")

private SupplierRequestsService service;



@PostConstruct

public void init() {

    leftGrid = service.populateLeftGrid();

}



public void setService(SupplierRequestsService service) {

    this.service = service;

}



public List<LeftGridBean> getLeftGrid() {

    return leftGrid;

}



public List<LeftGridBean> getFilteredLeftGrid() {

    return filteredLeftGrid;

}



public void setFilteredLeftGrid(List<LeftGridBean> filteredLeftGrid) {

    this.filteredLeftGrid = filteredLeftGrid;

}



public String getReqType() {

    return reqType;

}



public void setReqType(String reqType) {

    this.reqType = reqType;

}



public List<String> getUniqueLocations() {

    Set<String> locations = new HashSet<>();

    for (LeftGridBean lg : getLeftGrid()) {

        locations.add(lg.getProjectLocation());

    }

    uniqueLocations = new ArrayList<String>(locations);

    return uniqueLocations;

}



public Map<String, String> getUniqueRequestTypes() {

    Map<String, String> requestTypes = new HashMap<>();

    for (LeftGridBean lg : getLeftGrid()) {

        requestTypes.put(lg.getRequestType(), lg.getRequestType());

    }

    uniqueRequestTypes = requestTypes;

    return uniqueRequestTypes;

}

}

Domain:

public class LeftGridBean {

private String projectName;

private String projectLocation;

private String requestType;

private String requestName;

private String companyName;



public String getProjectLocation() {

    return projectLocation;

}



public void setProjectLocation(String projectLocation) {

    this.projectLocation = projectLocation;

}



public String getRequestType() {

    return requestType;

}



public void setRequestType(String requestType) {

    this.requestType = requestType;

}



public String getRequestName() {

    return requestName;

}



public void setRequestName(String requestName) {

    this.requestName = requestName;

}



public String getProjectName() {

    return projectName;

}



public void setProjectName(String projectName) {

    this.projectName = projectName;

}



public String getCompanyName() {

    return companyName;

}



public void setCompanyName(String companyName) {

    this.companyName = companyName;

}

}

and finally the service:

@ManagedBean(name="supplierRequestsService")

@SessionScoped

public class SupplierRequestsService {



@ManagedProperty("#{userManager}")

private UserManager usr;



public List<LeftGridBean> populateLeftGrid() {

    List<LeftGridBean> lgbList = usr.getSupplierLeftGridData();

    return lgbList;

}



public List<RightGridBean> populateRightGrid() {

    List<RightGridBean> rgbList = usr.getSupplierRightGridData();

    return rgbList;

}



public void setUsr(UserManager usr) {

    this.usr = usr;

}

}
