Okay. I found what is causing the setters not to be called. I have an
interceptor called ValueStackInterceptor (which is called prior to
ParametersInterceptors) that is placing a String variable "browser" on the
stack (please, see code below). If I comment out the line that places this
variable on the stack (see below) everything works fine. I am showing the
Interceptor and the line of code that is causing a problem.
Can someone please help me understand what is the problem with this code?
