How to know the contexte (simulation, code generation ...) when running a mask init function?

I got trouble in a bloc with a mask I have created in a personal librairi.

In the mask,I change some block type according to the parameter (set by user in the mask dialog panel).

It alow to change a block input to constant (and resip.) in order to remove inputs when unused.

The code I used is given here:

ParamCheckbox = get_param(gcb,'Pid_En');
BlockName = 'Enable';
MyBlocType = get_param([gcb '/' BlockName],'BlockType');
pos = get_param([gcb '/' BlockName],'Position');
orient = get_param([gcb '/' BlockName],'Orientation');
if(strcmp(ParamCheckbox,'on'))
    if(strcmp(MyBlocType,'Constant'))
        delete_block([gcb '/' BlockName]);
        add_block('built-in/Inport',[gcb '/' BlockName],'Position',pos,'Orientation',orient);
        set_param([gcb '/' BlockName],'OutDataTypeStr','boolean');
    end
else
    if(strcmp(MyBlocType,'Inport'))
        delete_block([gcb '/' BlockName]);
        add_block('built-in/Constant',[gcb '/' BlockName],'Position',pos,'Orientation',orient);
        set_param([gcb '/' BlockName],'OutDataTypeStr','boolean');
        set_param([gcb '/' BlockName],'Value','true');
    end
end

The problem is that during code generation, the init function is called.

It reset the corresponding port: the input port is removed and set again according to the user selection in dialog panel.

But the line connected to the block are not well "reconnected" to the block and the code generation produce a code where the connection is not done.

And that is not what I expect.

A solution I see is to "read" the execution context in the init function (simulation, code generation ...) and avoid to execute the code during code generation.

Any other solution is of course welcome.

What is strange, is that I allready use the same pattern in other library bloc without trouble.
