Disable button.
I have 3 buttons and two buttons must to be disabled if I select one of the 3 butttons.

I tried with the follow code on disabled property:
a!buttonArrayLayout(
buttons: {
a!buttonWidget(
icon: "check",
size: "LARGE",
value: local!buttonVal = 2,
style: "DESTRUCTIVE",
disabled: if(local!buttonselected = true, if(local!buttonVal = 1, "SECONDARY", false), false),
submit: a!save(local!buttonselected, true)
)
},
align: "CENTER"
)
