combo Box properties

21 September, 2007 - 19:24 — Anonymous

Hi!
I'm trying to use a combo box in my app. when I try to use the binding and the valueChangeListener properties, I get the following message:
"1: GENERIC: XML Parsing Error: Reference to undeclared namespace prefix: 'bf'. Location: Line Number 5, Column 57: Text:11: "\

The bf namespace prefix is already declared and used throught the app.

The console shows the next error:
781 ERROR - Servlet.service() for servlet jsp threw exception
javax.faces.el.PropertyNotFoundException: Base is null: testData

I'm working with backbase JSF edition.

Here is the code:

In the jsp:

 <bf:comboBox id="url" value="#{testData.url}" binding="#{testData.urlCombo}" >

                <f:selectItem itemValue="localhost"/>

                <f:selectItem itemValue="142.160.4.101"/>

        </bf:comboBox>

and in the bean:

public class TestDataBean {

        private UIBackbaseComboBox urlCombo;

        public UIBackbaseComboBox getUrlCombo() {

                return urlCombo;

        }

        public void setUrlCombo(UIBackbaseComboBox urlCombo) {

                this.urlCombo = urlCombo;

        }

I will apreciate any sugestions

Thanks!
