openFcn callback in library blocks

If I configure the openFcn callback of a subsystem that is a library block, the block disappears from the library browser.

Is it possible somehow (by manipulating the .mdl file in a text editor, e.g.) to use the openFcn callback in that context?

The background is, that I want that subsystem to be a switch that executes an M-file.

Thanks, Christian

Does the block appear in the library browser if you don't configure the OpenFcn? It seems like the more likely issue is that you may need to mask your subsystem and create either a dummy parameter or add something to the Documentation tab in the Mask.

Yes, it does appear in the library browser if I do not configure the OpenFcn callback. If I move the code to the PreSaveFcn, for example, the block does appear in the library browser.

To make sure, I have added text to the Documentation field of the block mask. It did not have an effect.

By chance, do you know another way to implement a 'button' in Simulink?

Is this an empty subsystem then? See if creating a dummy parameter called ShowInLibBrowser on the mask fixes the issue.

This solved the same issue I had.
