Gordon and Iko and Hilary,
thx for your assist but i am thinking i am not being very clear on my
previous post. (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!!
Luís Eduardo.
