(perhaps my bad english ;) what i want to do is a typecast from the String "true" to the boolean value true. this is why i cannot just throw the quotes on the assignment var btest:Boolean = "true"; i really need to convert a String to their correspondent boolean value. what you sugest to me is a workaround, rigth? i mean, all the ways to do typecast doesn't work. (so my first post). is this a bug? a limitation? or its just me? all this is to take a XML attribute (witch comes as String from httpservice) and setup a variable in my form. Yeah, there are another ways to do this (and i am using they for now) but the class Number() works with this kind of typecast... why not Boolean too? see, this typecast do works for numbers: var numTest:Number = Number("3.5"); trace("numtest = "+numTest); but this not to Boolean: var numTest:Boolean = Boolean("false"); trace("numtest = "+numTest); best regards and thank you again for your help!!
