Lets take a look at the paramsPrepareParamsStack:

 
      
      
      
      
      
      
          dojo\..*,^struts\..*
      
      
      
      
      
      
      
      
      
          dojo\..*,^struts\..*
       
       
       
           input,back,cancel,browse
       
       
           input,back,cancel,browse
       
 

There are 2 params interceptors. When you are setting excludeParams parameter in your action class, then this is probably set for the first params interceptor - parameter for the second interceptor stays default. Now, when the second params interceptor (with default excludeParams) is invoked, then given exception is thrown.

You can try to duplicate setting of the excludeParams parameter to set its also for the second interceptor:

 @InterceptorRef(value = "paramsPrepareParamsStack", params = {"params.acceptParamNames", "param1, param2", "params.excludeParams", "extraParam", "params.excludeParams", "extraParam", "validation.validateAnnotatedMethodOnly", "true", "validation.excludeMethods", "load"})})
