on-exception : how to show a customize error message

[dr_pompeii]

Hello guys

in this code

<action-state id="transaccioncompletacomprafacturaautohonda-dos">
	<bean-action bean="idConcreteProcesoCompraFacturaImplManagerObjectTransactional"
           method="procesoUpdateCabeceraFacturaCompraandInsertarArticuloAutoBO">
			<method-arguments>
				<argument expression="${flowScope.cabeceraFacturaCompraCommand}"/>
			</method-arguments>
	</bean-action>
	<transition on="success" to="transaccioncompletacomprafacturaautohonda-tres" />
	<transition on-exception="com.modelo.excepciones.MyPrimaryKeyException"
                  to="transaccioncompletacomprafacturaautohonda-uno" />			
</action-state>

my on-exception transition works fine, it goes to the desired view-state
the problem is how in the jsp rendered of the view-state
how i can show a customize error message if the MyPrimaryKeyException
was thrown?

thanks in advanced

Hi,
TransitionExecutingStateExceptionHandler is exposing the exceptions in flash scope, by name "rootCauseException".

Try ${rootCauseException.message}, and you'll get you exception message.

Also, you can for example do this:

<transition on-exception="com.modelo.excepciones.MyPrimaryKeyException"
                  to="transaccioncompletacomprafacturaautohonda-uno" >
      <set attribute="primaryKeyError" value="''" scope="flash"/> 
</transition>

and on view (JSP or whatever), you can test presence of "primaryKeyError" attribute and to show custom message.

Regards.
