No, we don't support it properly.
I could alias it to false if you need the code to run (but still not generate the event). I'm adding a ticket here: http://openmodelica.org:8080/cb/issue/1 … ation=true

You can also work around this bug by adding "#define terminal() 0" to OPENMODELICAHOME/include/omc/modelica.h

Thanks for the work around, but I need to write a text file after the simulation to export some data.

Could I use the "destructor" of a external object as a work around?

Yes, constructor/deconstructor is called properly when defined as top-level variables of a simulation.
External Objects work fine for non-array inputs and without any weird call mapping (like trying to send constant expressions...).

What does "top level" mean? I did some tests with a model that contains several blocks (each block has a external object inside).
In my test case the constructor and destructor seems to be called as expected.

Do I run into problems if the bock some were on a deeper model level?
I need a reliable solution because my block might be used somewhere in the model

Not created in a local scope (i.e. inside a function-call).
