I was implementing a web service the other day, it all went ok until I had to add another parameter on the web service function.

Suddenly my test template doesn't work, I suspected the problem has to do with the stubs not being refreshed, so I refreshed it using CF admin interface, but it didn't solve it.

I asked my workmate, he pointed me to a parameter in CFINVOKE method that I never heard before: refreshWSDL (my Eclipse didn't suggest me this parameter neither did Dreamweaver 8)... Setting this parameter to true solves the problem.
