"Behavior" parameter type at expressions, unexpected behavior

  1. Create a expression, and add the parameter Behavior (And the Object parameter aswell)

  2. Go to eventsheet and type the expression anywhere.

  3. After you fill the Object parameter, it will also ask you to fill the Behavior parameter.

  4. But you can’t fill the Behavior parameter because it wont accept nothing you type there. (It should not even ask you to fill anything.)

  5. The same applies for “true or false (boolean)” parameter, and probably many others.
