I must be missing something here, or I've just been staring at this
too long... I need to call a method on an instance that I access via
a factory. I just changed the method so that it takes a Collection as
it's single argument. However, when I try to specify that the argument
to the method is a <list>, I believe the MethodInvokingFactoryBean
is interpreting my <list> as the list of arguments instead of an
argument that is a list (Collection). Is there a way to do this?
