Facelets ui:debug not working with spring web-flow -> throwing exception [SWF-1131]

[spring-operator]

Dominik Dorn opened SWF-1131 and commented

When using facelets to run spring web flow, spring web flow doesn't understand the modifications done to the url by facelets when opening the debug window (CTRL + D) . It throws an exception:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.18 logs.

I've attached my sample application.

extract it and build it with maven mvn clean compile package then deploy the war in the target folder to your tomcat.

then browse to http://127.0.0.1:8080/dc-webapp/register/registration-flow then press CTRL+D

In case anyone else runs into this, and since https://facelets.dev.java.net/issues/show_bug.cgi?id=312 has gone unfixed for so long, I posted the extensive patch for Facelets over here:

http://datenschwanz.net/2009/12/31/facelets-uidebug-and-spring-web-flow/

This really isn't an SWF bug, unless execution keys are going to be passed around some other way...

I have the same issue. My workaround is to manually change the offending '?' by a '&' in the debug popup.

I'm experiencing something very simillar - when "AdsBot-Google" visits flow page NumberFormatException gets thrown, and in access logs it can be seen that AdsBot-Google was issuing GET with URL that contains two question marks, first followed by SWF's execution parameter, and second one followed by what seems as AdsBot-Google parameters.
