Same ajaxErrorHandler called for multiple exceptions

vovan · 16 Jun 2014, 14:04

Hello!

Why for every thrown exception always called same(first) ajaxErrorHandler ?
This code is from showcase. I just added form for buttons and chaged titles of error handlers.

Code: Select all

        <!-- In title and body you can use HTML tags too, because the values are not escaped. -->  
        <pe:ajaxErrorHandler  
            title="Error2"

            widgetVar="myAjaxErrorHandler" buttonOnclick="myAjaxErrorHandler.hide()"  
            type="javax.faces.application.ViewExpiredException" />

                                </h:panelGrid>  

                            </p:tab>

                                <div style="overflow: auto; height: 300px; width: 700px;">  
                                    {error-stacktrace}  
                                </div>  
                            </p:tab>  
                        </p:tabView>  
                    </h:form>  
                </div>  
            </f:facet>  
        </pe:ajaxErrorHandler>  
        
        <h:form>
            <!-- AJAX actions, which throw exceptions -->  
            <p:commandButton action="#{ajaxErrorHandlerController.actionThrowNullPointer}"  
                             value="Example first definition" />  
            <p:commandButton action="#{ajaxErrorHandlerController.actionSimulateViewExpiredException}"  
                             value="Example second definition" />  
            <p:commandButton action="#{ajaxErrorHandlerController.actionWrappedException}"  
                             value="Example third definition" />  
        </h:form>

    </h:body>
</html>

Here what i get if i press every button:

How can i set different handlers for different exceptions ?
Thank you.

Might be because of same widgetVar names? Please try with unique values.

But ajaxErrorHandler invoked based on exception type only.

Bean code:

Code: Select all

import javax.enterprise.context.RequestScoped;
import javax.faces.FacesException;
import javax.faces.application.ViewExpiredException;
import javax.faces.context.FacesContext;
import javax.inject.Named;

@Named
@RequestScoped  
public class AjaxErrorHandlerController {  
  
    public String actionThrowNullPointer() {  
        throw new NullPointerException("This is my null pointer exception!");  
    }  
  
    public String actionWrappedException() {  
        Throwable t = new IllegalStateException("This is wrapped illegal state exception!");  
        throw new FacesException(t);  
    }  
  
    public String actionSimulateViewExpiredException() {  
        throw new ViewExpiredException("This is simulated ViewExpiredException",  
                                       FacesContext.getCurrentInstance().getViewRoot().getViewId());  
    }  
}

Not this way.If you can make it as simple maven proj then only it will be easy to test your sample app.
