Hi,

I want to put an tag on an activescaffold form. The docs say  
I can use a helper or a form overhide… but when I put a tag  
in one of those, it gets stripped. I think it’s some security stuff.  
But I need to trigger an action when the form is loaded to adjust some  
presentation logic. How can I put the script tag into my form?

Thks,

Bruno R.
