How to change output text conditionally

Question

I have a supplier table with column gst_invoice_type. The table have two rows, with value F and S.

In my PrimeFaces dataTable, I also created a table with column Gst_Invoice_Type with drop down menu filter as below code

<p:column filterBy="#{vo.gstInvoiceType}" headerText="GST Invoice Type." sortBy="#{vo.gstInvoiceType}"
                        style="width:130px;" visible="false">
                    <f:facet name="filter">
                        <p:selectOneMenu style="width:110px; vertical-align:middle;" autoWidth="false"
                        onchange="PF('varTable').filter()">
                            <f:selectItem itemLabel="ALL" itemValue="" noSelectionOption="true" />
                            <f:selectItem itemLabel="Full Tax Invoice" itemValue="F" />
                            <f:selectItem itemLabel="Simplified Invoice" itemValue="S" />
                        </p:selectOneMenu>
                    </f:facet>
                    <h:outputText value="#{vo.gstInvoiceType}"/>
                </p:column>

When select All, all data (F and S) will be retrieved and located in Gst_Invoice_Type, which working correctly. But is it possible to let the F and S display as Full Tax Invoice and Simplified Invoice ?

Answer 1

Simply insert two conditionally rendered <h:outputText /> elements with different values.

<p:column>
  <h:outputText
    value="Full Tax Invoice"
    rendered="#{vo.gstInvoiceType eq 'F'}"
  />
  <h:outputText
    value="Simplified Invoice"
    rendered="#{vo.gstInvoiceType eq 'S'}"
  />
</p:column>

Another option is to do the mapping programmatically in a bean method like:

<p:column>
  <h:outputText value="#{bean.map(vo.gstInvoiceType)}" />
</p:column>

with

public class Bean {
  public String map(String input) {
    // however you implement your mapping
  }
}
