Flex / Flash CS3 Error #3553

Posted on by

Warning: 3553: Function value used where type void was expected. Possibly the parentheses () are missing after this function reference.

Description:
This is one of the best descriptions that I have seen for a Flash Error. This Flex/Flash Error is actually just a Flex/ Flash Warning. This error/warning means exactly what it says. You just forgot the parentheses () when you tried to make a method call.

Fix:
Add the Parenthesis

Bad Code:

var myTime:Timer = new Timer(1000, 3);
myTime.start;

or

var myDate:Date = new Date();
myDate.getDate;

Good Code:

var myTime:Timer = new Timer(1000, 3);
myTime.start();

or

var myDate:Date = new Date();
myDate.getDate();

As always Happy Flashing

  1. I get this warning on a dispatchEvent

    vTileList.dispatchEvent(new Event(dd_tile_list.LIST_REORDERED, vReorder));

    The code works but I don’t like having the error there, and in this case adding the parentheses is not an option.

    Do I have to live with it?

  2. if (typeof fn == “function”) fn //if defined, execute it

    this line cause #3553 warning too. But fn with parentheses() in the expression execute anyway that cause error.

  3. Hi!

    I want to improve my SQL knowledge.

    read more about SQL for my occupation as db2 database manager.
