Why the validator can't display the error message on the popup dialog?

Question

I have input text with a validator and a custom ok button and a cancel button on the popup dialog.When I click the ok button,the validator will validator the input value on the input text,but it just close the popup dialog without display the message firstly.The point is it does validate the value but doesn't display the message.Can anybody help?

Answer 1

It seems if I use the button which is associated with the dialog the validator works well,but if I use the custom button the error message doesn't display. the environment is 11g.
the code of the page is :
<af:form>
<af:popup id="copyPopupDialog" contentDelivery="lazyUncached">
<af:dialog title="validator" closeIconVisible="false" type="none">
<af:inputText id="copyReportsetCode" styleClass="" label="code"
value="11"
validator="#{reportSetManagedBean.validatCode}"></af:inputText>
<f:facet name="buttonBar">
<af:panelGroupLayout layout="horizontal" halign="right">
<af:commandButton text="ok"/>
<af:commandButton text="cancel" immediate="true"/>
</af:panelGroupLayout>
</f:facet>
</af:dialog>
</af:popup>
<af:commandButton text="commandButton 1">
<af:showPopupBehavior popupId="copyPopupDialog"/>
</af:commandButton>
</af:form>
the code of the managedbean is:
package david;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.ValidatorException;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import java.util.regex.Pattern;

public class ReportSetManagedBean {
public ReportSetManagedBean() {
public void validatCode(FacesContext facesContext, UIComponent uIComponent,
Object object) {
FacesMessage msg = new FacesMessage("eror");
throw new ValidatorException(msg);
}
