Any one can enable or disable buttons on veiw by change parameter in url , I think using short encoded url insetad

[Alaa Besher ( NCTR )]

look at this url parameter :

http://localhost:8080/form/view?model=product.product&view_mode=[u%27tree%27%2C%20u%27form%27]

in this view_mode parameter I can add another veiw button in it like this :

view_mode=[u%27tree%27%2C%20u%27form%27u%27graph%20u%27gantt%27]

and it work also

I suggest to using short url instead of current url
