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
Description: org.apache.avalon.framework.CascadingRuntimeException: "resource://org/apache/cocoon/forms/flow/javascript/Form.js", line 144: uncaught JavaScript exception: at showCart (file:/D:/home/domains/192.168.42.20/shop/flows/testShop.js, Line 59) at (resource://org/apache/cocoon/forms/flow/javascript/Form.js, Line 144): java.lang.ClassCastException: Class cannot be casted to array
Here the entire stacktrace:

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?
