quick question - making button visible if two conditions are met

[madhooper]

I simply want a button to be visible is once condition is true and another condition is false. Shouldn't this line of code work?

<mx:Button

id="Btn"

label="

Submit"

color="

#FF0000"

enabled="

{islRequired}"

visible="

{!.isAdmin}  {isRequired}"

click="submit()"

/>

isadmin = false

isrequired = true

the button should be visible

Am I missing something?

Maybe you miss OR (||) or AND (&&), but I never use at mxml

visible="{!.isAdmin && isRequired}" 

Works?

Best Regards,

Miguel
