Composite Visible Properties.

Hi,

I got many toolboxes, and i grouped it. 
Processbook named it by Composite1.

I would like to make my toolboxes invisible.

I tried "textbox1.visible = false", but it does not turn invisible because it is in a composite.

So, one solution is something like: composite1.visible = false. It does not work either.

Does anyone has a solution?

Thanks!
