Asked by: aciang

Dear Experts,

I have jsf DataTable and checkbox problem
I have a List listCountries with fields: countryId & countryNm

            <h:dataTable value="#{pLM0001.listCountries}"
                              var="f0001"
                              binding="#{pLM0001.htmlDataTableCountry}"
                              border="1">
                  <h:column>
                        <h:outputText value="#{f0001.countryid}"></h:outputText>
                  </h:column>
                  <h:column>
                        <h:outputText value="#{f0001.countryNm}"></h:outputText>
                  </h:column>
                  <h:column>
                        <h:selectBooleanCheckbox value="#{pLM0001.bolSelected}">
                        </h:selectBooleanCheckbox>
                  </h:column>
            </h:dataTable>

End users can pick the countries they want to select.
The problem is, how can I get which countries are selected?

I am still a rookie in jsf and java environment, please kindly help :).

Thanks in advance.

Well, it depends on your bean, etc. and you haven't provided a lot of information. However the general solution is that you have to get hold of the underlying UIData object that your table depends on. The easiest place to handle this is in your backing bean, where you can process the selected items. So you might have something like:

      public void button1ClickAction() {
        int iX = myUiData.getFirst();                 // Get the first record in the current page in the table
        int rows = myUiData.getRows();              // Get the size of the displayed data table
        // Search the table
        for (; iX< rows; iX++) {
            // Start at first row displayed
            myUiData.setRowIndex(iX+rows);
 
            // Get the bolSelected value for this item
 
        }
     }

You might like to look at the Repeater example in the JSF downloads for examples on how to use the UIData objects.
