Are you just missing the getter for user? Struts2 has to call

I never have these two attributes pointing to the same property.  It may 
work, but it's the first place I'd look for type conversion problems.
My list attribute always points to a List with key and value entries for 
the select and the name attribute always points to a String[] that will 
contain the selected key values.
