Type Conversion Problem

i am trying to take advantage of error reporting feature for Type Conversion Using ValidationAware which is by default extended by the ActionSupport.

Expected Output : On entering data using incompatible type the system must return the input page with necessary error message i.e. BAD AGENT. . . You forgot your code. It should be a number

Actual Output : returns an error with following stack

WARNING: Error setting expression 'agent_code' with value '[Ljava.lang.String;@ce717a'

Works fine for me, although your "INPUT" result is named incorrectly unless you've redefined the workflow interceptor to use the non-standard name.
 
I agree. Here's the link: http://aspose.com/file-tools
