CascadingRuntimeException when usinf radio-buttons in CForms
Hi,
I am sort of new to CForms and am working myself into them at the
moment. Unfortunately I ran into problems when using radio-buttons in my
CForms.
Everytime a radio-button is checked in a Form i get the folowing error:
Message: Class cannot be casted to array

the line of my flowscript, which is named in the error is a simple:
cartForm.showForm("shoppingCartTemplate.jexl");
Do you have any hints for where I have to look for fixing this error? Do
you need any more information?

Re: CascadingRuntimeException when usinf radio-buttons in CForms
Posted by Christofer Dutz <du...@c-ware.de>.
As you can see in the Flow-Script all form information is mapped into an
xml-document, which is created for each session.
This worked without problems with every other datatype. Just these
little radio-buttons are bugging me :(
Can you see any problems?

How to test for invalidated session in Flowscript
Posted by Geert Josten <Ge...@daidalos.nl>.
Hi all,
I am trying to find out whether a session has been invalidated or not in FlowScript, but haven't
succeeded so far. The session object doesn't support isValid(), the request object doesn't support
isRequestedSessionIdValid(), nor does cocoon.session return a null or boolean when the session is
not available or invalidated. I'm out of ideas. Anyone?
I noticed the SessionIsValidAction, but I don't see how to port the Java to Flowscript...
Cheers,
Geert

Presumably a syntax error in the declaration of where you're storing the info...
Are you using binding, or doing ot from flow, or...?
Post that here and it might be obvious to somebody.
