"sf_intern​al_predica​teOutput" outputs in workspace during model simulation??

Hi, if I run my model, there are lots of following messages showing in workspace. Does anyone know how I can change my model to delete these messages?? Thanks

sf_internal_predicateOutput =
     0

sf_internal_predicateOutput =
     1

sf_internal_predicateOutput =
     0

sf_internal_predicateOutput =
     0

sf_internal_predicateOutput =
     0

Hey, you are not alone, I have the same messages and have not found a solution yet. So hopefully someone has a solution soon.

I had this problem with a transition guard looking like this: [after(3,tick), receive(my_msg)]

It wasn't working as intended either and I changed it to this expression: [after(3,tick) && receive(my_msg)]

After that the messages disappeared. So I'm guessing in the first expression the message receival isn't part of the condition but rather an action that somehow gets executed after the time check. And that action doesn't have a semicolon after it, so its return value gets printed.

Know the question is old, but reached this during searching, so adding my 2 cents.

Had the same problem and made a similar change to get it to work:

changed:

[...
    value > low_ limit &&...
    value < high_limit ...
    ]

to:

[value > low_ limit &&...
    value < high_limit]
