pageflow and exception question

pietermartin Nov 26, 2007 3:31 PM

Hi,

I am struggling to get exception handling to work with jpdl pageflows. Not sure whether it is suppose to work or whether the code needs decision elements everywhere to check for failures.

Currently I get an exception with the page breaking

my pageflow-definition is as follows

 <page name="captureContactDetails" view-id="/signyouup/contactDetails.xhtml" no-conversation-view-id="/signyouup/choosePhone.xhtml">
 <redirect />
 <transition name="back" to="capturePhoneDetails">
 </transition>
 <transition name="next" to="isCaptureContactSuccessful">
 <action expression="#{webCustomerAction.persistContact}" />
 </transition>
 </page>

the action class

@Name("webCustomerAction")
@Scope(ScopeType.CONVERSATION)
public class WebCustomerAction extends SeamedAction {

 public String persistContact() {
 log.info("persistContact");
 if (true) {
 throw new SelfcareApplicationException("O my what absolute horror!");
 }
 }
}

in pages...

 <exception>
 <end-conversation/>
 <redirect view-id="/error.xhtml">
 <message severity="error">#{org.jboss.seam.handledException.message}</message>
 </redirect>
 </exception>

The stack trace...

22:11:13,652 INFO [WebCustomerAction] persistContact

I see that in the dvd example app the action methods are themselves ocurring in a try catch block
eg.

 public String saveUser() {
 if (!isValidNamePassword()) {
 facesMessages.add("User name #{customer.userName} is not unique");
 return null;
 }

 try {
 em.persist(customer);
 sessionContext.set("currentUser", customer);
 Actor.instance().setId(customer.getUserName());

 identity.setUsername(customer.getUserName());
 identity.setPassword(customer.getPassword());
 identity.login();

 facesMessages.addFromResourceBundle("createCustomerSuccess");
 return "success";
 } catch (InvalidStateException e) {
 InvalidValue[] vals = e.getInvalidValues();
 for (InvalidValue val: vals) {
 facesMessages.add(val);
 }

 return null;
 } catch (RuntimeException e) {
 ctx.setRollbackOnly();

 facesMessages.addFromResourceBundle("createCustomerError");

 return null;
 }
 }

Is this the preferred way?

Any pointers appreciated.

I am using seam-2.0.0.GA and jboss 4.2.2.GA

Thanks

Handling exceptions from JBPM via Seam exception handling should work. If it isn't please create a JIRA issue and attach an example of the problem with reproduction instructions.

Here, the wrong exception is being thrown http://jira.jboss.com/jira/browse/JBSEAM-2152

The JIRA issue Pete linked to is the reason for your error. A workaround is to add parenthesis to the method call in the EL (so "#{webCustomerAction.persistContact()}" ).

Even when you do fix that, the redirection and/or message showing still might not work properly because of some other Seam bugs (see http://jira.jboss.org/jira/browse/JBSEAM-2139)
