The method app.listToolbarButtons() does not work in Acrobat X.
To test, try to execute this in the JS console. It shows No output.
If Adobe has discontinued this function in X, then it should have produced a "Function Not defined" output, but it does not say this.
However, it also does not return anything.
Is there a security or other option I need to enable or set..
Does anybody know anything about this.
It's due to the significant change in user interface with Acrobat 10. What are you trying to accomplish that you need the names for?
