Primefaces dataTable, filter on localized enum values

Question

I have a p:datatable that is populated by a list of domain objects

Each domain object has a value that is tied to an enum PrivateIndustry : P, K or N , that corresponds to a database value.

these values are then presented in the p:dataTable via localization, labels_LOCALE.properties to make them human readable, with the com.package.PrivateIndustry.P/K/N syntax.

This works okay for readability, but when i Use PF('dataTableId').filter() to filter the dataTable, I cannot filter for the localized values, only the pure enum values (ie P, K or N)

ie:

    <p:column headerText="#{labels.header}"
         filterBy="#{domainobject.privateIndustry}" filterStyle="display: none"
         sortBy="#{domainobject.privateIndustry}" >
         <h:outputText value="#{domainobject.privateIndustry}"/>
    </p:column>

I can remedy this by populating the names in the domain object as String using ResourceBundle.getString("com.package.PrivateIndustry...") but this seems rather unneccesary and convoluted.

Can I parse filterBy="" with a better value, or make PF().filter() work on the client side data?

Answer 1

This is the way I solved the functionality in code rather than in xhtml:

upon creation of the domain objects, in the constructor,call a method that generates a String containing the parsed String from the enum value:

import java.util.ResourceBundle;
import javax.faces.context.FacesContext;

public class DomainObject   {
    private PrivateIndustry privateIndustry;
    private String enumStringValue;

    public void generateEnumStringValue() { 
        ResourceBundle rb= ResourceBundle.getBundle("labels",FacesContext.getCurrentInstance().getViewRoot().getLocale());
        this.enumStringValue = rb.getString("com.package.DomainObject.PrivateIndustry." + privateIndustry.name());
    }
    public String getEnumStringValue() {
        return emumStringValue;
    }

    public enum PrivateIndustry {

        P("Private"),

        N("Industry"),

        K("Combined");
        private final String name;

        PrivateIndustry(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }      
    }
}

and then, in the bean:

public String getEnumStringValue(DomainObject domainObject) {

    return domainObject.getEnumStringValue();
}

and finally:

<p:column headerText="#{labels.header}"
          filterBy="#{backingBean.getEnumStringValue(domainObject)}"
          sortBy="#{backingBean.getEnumStringValue(domainObject)}">
    <h:outputText value="#{domainObject.privateIndustry}"/>

</p:column>
