Question

Global Exception handing with Spring WebFlow Flow.

I am working in a Spring webflow project and I would like to know if anyone knows how to add sometype of global exception handing in the flow so if any of my java calls throw a example it will catch in and bring in to the same error system for the full system?

My old flow worked with out a issues:

<var name="member" class="xxxx" />
<decision-state id="checkIsInPending">
   <if test="flowControllerActions.isInPending(member)" then="endStateMemberPending" else="name" />
</decision-state>

once I added the global to it, I started to get a error.

<var name="member" class="xxxxx" />

    <global-transitions>
        <transition on-exception="java.lang.Exception"
                    to="SystemException" />
    </global-transitions>


    <decision-state id="checkIsInPending">
        <if test="flowControllerActions.isInPending(member)" then="endStateMemberPending" else="name" />
    </decision-state>

Here is my error:

org.xml.sax.SAXParseException; lineNumber: 29; columnNumber: 40; cvc-complex-type.2.4.a: Invalid content was found starting with element 'decision-state'. One of '{"http://www.springframework.org/schema/webflow":on-end, "http://www.springframework.org/schema/webflow":output, "http://www.springframework.org/schema/webflow":exception-handler, "http://www.springframework.org/schema/webflow":bean-import}' is expected.

Try to rearrange XML tags. You are getting this exception because your flow XML does not comply with XSD. Myabe just put global-transition in the end
