how i can handle this: user clicks many times in a link

[dr_pompeii]

Hello guys

i have a flow process where in some jsp/state, to forward to other state the user must do click in some link, the problem is that for test purpose we use a simple machine like server
the user see a delay in the request process , so it proceed to make more clicks (thinking that it would be make the request more fast)
, so i recieve an exception i cant remember

how i can handle this?

thanks in advanced

This is the general solution with Spring, an exception resolver. If a Spring Web Flow exception NoSuchFlowExcecutionException is thrown it displays the jsp flowException.jsp in my WEB-INF/views/jsp/error directory:

    <beans:bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <beans:property name="exceptionMappings">
            <beans:props>
                <beans:prop key="org.springframework.webflow.execution.repository.NoSuchFlowExecutionException">
                    error/flowException
                </beans:prop>
            </beans:props>
        </beans:property>
    </beans:bean>

Make sure the full class name is correct for the exception you're getting.

Hello lumpynose

thanks for the reply

your suggestion seems nice, but i have a doubt,
it would be thrown why ny flow in my app, so
if i go to the jsp error, i need a way back to the previous view-state in some flow
i dont know if when the exception NoSuchFlowExecutionException when is caught
the flow is terminated
here
http://static.springframework.org/sp...Exception.html
only i see

Thrown when the flow execution with the persistent identifier provided could not be found. This could occur if the execution has been removed from the repository and a client still has a handle to the key.

thanks in advanced

Yes, the exception way is not as nice as one might like.

Hi dr_pompeii,

As far as I know swf is designed to handle the double submit, when a state is reached and start its treatment it's locked and a new flow execution key is computed to make sure that any "double request" (holding the hold key) is not elligble for going on the flow.

So could you me more exact on the exception you get when double click occurs.
