Your 'setThing' and 'getThing' methods have inconsistent signatures.
They need to comply with the JavaBeans specification. In particular,
they both need to deal in the same value types -- so either change the
type of the 'value' parameter to Object in setThing, or change the
return type of getThing to String. I think that's your problem.

OK, I'm climbing up the walls trying to make Struts populate a map-backed action
form. This should be a simple task but I cannot get it to f*&king work and it
is driving me insane... The reset method is called before the form is first
displayed and the resulting jsp is populated with the value set in the reset
method, i.e. it's accessing the map correctly. However, when the form is submitted
the reset is called again but the form bean is not populated from the request
before it gets to the action...
