Error handling with richfaces

[iimirela]

Hello,

I'd like to manage errors using the modalPanel. I'm using richfaces 3.3.0, templates, and I'd like to achieve the following: whenever there is an error (like.. wrong format in user input, but also oracle errors when saving/deleting) to show the message error in a modal panel.

Any suggestions?

Thanks,
Ioana.

1) surround the modal panel with a4j:outputPanel with ajaxRendered=true
2) define showWhenRendered="not facesContext.maximumSeverity==null" on the modal
3) place rich:messages inside.
4) include to your main template.

 <a4j:outputPanel ajaxRendered="true">
 <rich:modalPanel showWhenRendered="#{not (facesContext.maximumSeverity==null)}">
 <rich:messages passedLabel="Data is allowed to be stored." layout="list">
 <f:facet name="header">
 <h:outputText value="Entered Data Status:"></h:outputText>
 </f:facet>
 <f:facet name="passedMarker">
 <h:graphicImage value="/images/ajax/passed.gif" />
 </f:facet>
 <f:facet name="errorMarker">
 <h:graphicImage value="/images/ajax/error.gif" />
 </f:facet>
 </rich:messages>
 </rich:modalPanel>
 </a4j:outputPanel>

Beautiful. Now of, course, depending on the page, I have different types of errors, and different messages. Should I use a binding? Can I set the message?

Should I use a binding?

Please clarify what binding are you referring to?

Can I set the message?

Messages are customized at component producing messages (e.g. using requiredMessage attribute) or at application level using message bundle. rich:messages just displays them.

Right. I want to customize messages at application level, using messages bundle. How can I do that?

P.S: I meant a binding to the messages component... to set the message? Obviously I'm new in jsf :(

Please take a look: http://www.ibm.com/developerworks/library/j-jsf3/ or consult JSF specification documents.

Binding is not required unless you want to create/modify component programmatically.
