missleading warning message

I have :

var somefunc:Function =giveMeMyFunc();

if(!somefunc) …

I get very misleading warning :

“Function value used where type Object was expected. Possibly
the parentheses () are missing after this Function refference”

but if I do this :

if(somefunc==null) no warming shows up,

this sounds like a bug?

is this a bug?

Hey,

do you happen to come from a PHP world???

If so, then if (!var) is possible in PHP, but not in
ActionScript.

ActionScript is strong(er) typed then PHP so you have to
compare a variable against something. In PHP variable can change
type.. in ActionScript not.

So if (!variable) means nothing in Actionscript.

For example if var==null, what is !var ??

I dont agree,

in AS if (!var) means same as if (var==null) , remember AS
is based on EcmaScript and last I checked EcmaScript still allows
this kind of notation.

its actualy very easy to test :

var test:Object = null;

Alert.show(!test+”"); // output true

Alert.show((test==null)+”");// output true

test = new Object();

Alert.show(!test+”"); // output false

Alert.show((test==null)+”"); // output false

P.S I come from java world .

Hey,

properly you are right. I have had the same, but now trying I
couldn’t duplicate it.

Me coming and doing a lot with database I find the while if
(!Object) very strange where a object can be null.

SELECT NULL; — results in NULL

SELECT NOT NULL; — result in null

Both of the below statements return true

select NULL IS NULL;

select (NOT NULL) IS NULL;

Anyways, I started to get used to specifying what I really
mean eg:

I am nowdays using if (object == null)

I think in the above message that AS might get confused
because it finds a function with the same name, might be a bug
indeed….
