Data exchange between a C-mex S-function and a function-call subsystem

Hi,
I have a Simulink model in which several outputs from a S-Function are connected to a function-call subsystem, also called by the S-Function.
However, I am observing a data inconsistency because the function-call subsystem is executed with the default values of the S-Function outputs and not with the calculated ones inside the mdlOutputs S-Function method.
I think that function-call is executed before the S-Function updates its outputs. Is there any way of solving this?
Thanks,

Are the S-function outputs that act as the function-call subsystem inputs computed after the function-call is triggered? As explained here Simulink interrupts the S-function's output function as soon the function-call subsystem is called and returns to the remaining statements after the subsystem has executed. Perhaps you should trigger the function-call at the bottom of your mdlOutputs function?
