How can I obtain the parameter structure when using model references with the Rsim target in Simulink 7.4 (R2009b)?

I am using Rsim target to simulate my model in Simulink 7.4 (R2009b). In the model I am using model references and I want to obtain the parameter structure with this command:

 rsimgetrtp('main_model','AddTunableParamInfo','on')

But this only returns an empty structure.

Attached to this solution you will find a small demo model which demonstrates how to obtain the parameter structure from a model which uses model references with the following command:

 >>rsimgetrtp('main_model','AddTunableParamInfo','on')

Which will return A and K in the struct:

 You will get this output:

 ans = 

     modelChecksum: [809202561 3.2719e+009 3.4891e+009 1.8594e+009]

        parameters: [1x2 struct]

Please follow these steps to obtain the parameter structure:

1) Define A and K as Simulink.Parameter and set the storage class to SimulinkGlobal

2) Define K as argument for the model reference:

right-click on the model reference --> Model reference parameters --> Model argument value: K

3) Inline parameters: Configuration Parameters --> Optimization --> Inline Parameters

4) Now run rsimgetrtp('main_model','AddTunableParamInfo','on') from the MATLAB command line
