java.lang.reflect.InvocationTargetException when using Indexed properties

[Julio Cesar De Salvo <jd...@itechnology.com.ar>]

Hi, 
 
I get this error when sending the parameters to action that saves the
information in tha database, the creation of the form is successfull.
 
I guess that might be something related with the getters/setters in the
ActionForm as when I change this methods names the exception changes to
NullException.
 
Any ideas, about how to name the getters/setters for the indexed
properties (in my case is a bean with Strings).
