Flash CS3 / Flex 2 Error #1084

Posted in Flash, Flex, errors at 6:51 pm by Curtis J. Morley

ActionScript Error #1084: Syntax error: expecting rightbrace before end of program.

Error 1084 is the general error number for syntax errors. ActionScript Error #1084 can be any number of errors. I will keep this one up to date with all the variations I find and how to fix them.

AS3 Error 1084: Syntax error: expecting rightbrace before end of program

This is a very easy one. This error just means that you are most likely missing a right brace. Or you have nested code improperly.

Bad Code:

package com.cjm
{
class CoolClass {
function CoolClass () {
trace("Something cool")
}
}

Good Code:

package com.cjm
{
class CoolClass {
function CoolClass () {
trace("Something cool")
}
}
}

Please make note of the third bracket at the end of the good code.

ActionScript Error #1084: Syntax error: expecting colon before semicolon.

You will most likely get this error if you are using a ternary statement and you forget to use a colon, forgot the last part of your ternary, or you replace the colon with a semicolon. This is illustrated in the following example:

Bad Code:

me.myType == "keys" ? trace(keys);

or

me.myType == "keys" ? trace(keys) ; trace(defs);

Good Code:

me.myType == "keys" ? trace(keys) : trace(defs);

Flash/Flex Error #1084: Syntax error: expecting identifier before leftbrace.

Description:
This Flash/Flex Error is reported when you left out the name of your class. The 'identifier' that it is looking for is the name of your class.

Fix:
You will see in the code below that you just need to add in the name of your class and the error will go away.

Bad Code:

package com.cjm.somepackage {
public class {
}
}

Good Code:

package com.cjm.somepackage {
public class MyClass {
}
}

Flex/Flash Error #1084: Syntax error: expecting leftparen before colon.
or
Flex/Flash Error #1084: Syntax error: expecting rightparen before colon.

Description:
These AS3 Errors are reported when you the order of the parenthesis and colon are not in the proper place or the parenthesis is missing.

Fix:
The AS3 code below demonstrates the placement error. Properly order the items and the error will disappear. Also, make sure that a parenthesis is not missing. The 'Bad Code' gives an example of leftParen and then right paren in the order.

Bad Code:

public function ScrambleSpelling:void (s:String)
or
public function ScrambleSpelling(s:String:void

Good Code:

public function ScrambleSpelling (s:String):void

Flex/Flash Error #1084: Syntax error: expecting rightparen before semicolon.

Description:
This AS3 Error is reported most often when the parenthesis is missing.

Fix:
Make sure that a parenthesis is not missing. The 'Bad Code' gives an example of leftParen and then right paren in the order.

Bad Code:

tempArray.push((middle.splice(middle.length-1) * Math.random());
or
tempArray.push(middle.splice(middle.length-1) * Math.random();

Good Code:

tempArray.push(middle.splice(middle.length-1) * Math.random());

Flex/Flash Error #1084: Syntax error: expecting identifier before 1084.

Description:
This AS3 Error is reported when you have begun a package, class, function/method or variable with a numeric character rather than an Alpha character, _(underscore), or $(dollar sign).  In the Flash Authoring environment it won't allow you to add numerics as the first character in an instance name or in the linkage but with code it just gives this crazy error.

Fix:
Make sure to name your package, class, function/method or variable with a Alpha character, _(underscore), or $(dollar sign).

Bad Code:

package 1084_error
{
class 1084_error {
function 1084_error () {
var 1084_error:int = 123;
}
}
}

Good Code:

package error_1084
{
class error_1084 {
function error_1084 () {
var error_1084:int = 123;
}
}
}

P.S.  It is probably not a good idea to give everything the same name as in the examples above.

AS3 Error #1084 will rear it's many heads according to the particular syntax error at the moment. I will post every variation of this error that I can find.

Once again Happy Flashing

    Hi,

    I don’t use Flash CS3 but a person I know does and they apparently got Error #1084: Syntax error: expecting rightbrace before semicolon. And that was for the code below, specifically for line two. I know this code works in my version of Flash I was wondering whether you could point out where this code could be incorrect for AS3…

    for (var i=0; i

  2. Curtis J. Morley said,

    August 13, 2007 at 3:54 pm

    The code is not incorrect just incomplete. The example you have is just the beginning of a complete block. Something like this:

    for (var i=0; i<=20; i++){
    trace(i)
    }

    This will produce the output 0 through 20 in the output window. If you have more code for me to look at I would be happy to help.

    Thanks,

    Curtis

    ekion,

    I have put up some new examples that handle the case that you are talking about. Hope this helps. I like your site and look forward to seeing the redesign.

    i got one that said :

    1084: Syntax error: expecting rightparen before dot.

    here is my code:

    function startGame(event.MouseEvent) {
    gotoAndStop(”playgame”);
    }
    stop();

    ok i fixed that one but now i have an error that looks like this:

    1084: Syntax error: expecting identifier before playgame.

    the source is:
    event.”playgame”.parent.gotoAndStop(”playgame”);

    here is my code:

    function startGame(event:MouseEvent){
    event.”playgame”.parent.gotoAndStop(”playgame”);
    }

    stop();

    any help?

  12. Curtis J. Morley said,

    Zach,

    Try this code

    function startGame (e:MouseEvent)
    {
    gotoAndStop(”playgame”);
    }

    The difference is the semicolon in place of the dot. The semicolon “Types” the parameter being passed instead of trying to access a method/parameter of a method.

    You would call this function with an evenListener like I have below.

    SomeObject_mc.addEventListener(MouseEvent.CLICK, startGame)

    Hopefully this helps you solve Flash Error1084

    Happy Flashing,

    So I have a video clip in a fla, an as file named MainTimeline that I use for the document class in the fla. But I am getting a error 1084: expecting identifier before 1: package 1_fla

    I am just missing something I am not seeing or did I do something wrong?

    here is the code in the as file (no code at all in the fla):
    package 1_fla
    {
    import flash.display.*;

    dynamic public class MainTimeline extends MovieClip
    {

    public function MainTimeline()
    {
    addFrameScript(1796, frame1797, 1797, frame1798, 1798, frame1799);
    return;
    }// end function

    function frame1798()
    {
    stop();
    return;
    }// end function

    function frame1799()
    {
    stop();
    return;
    }// end function

    function frame1797()
    {
    ExternalInterface.call(”nextPage”, null);
    return;
    }// end function

    } // end class
    } // end package

    Aaron,

    Thanks for submitting this comment. I have added the solution to the list of errors in the main post because of your bug. This one is actually a simple yet very misleading one. The reason it pops up this error is because you started your package name with a number.

    package 1084_error{
    }

    In Flash you cannot start any name with a number or else you will get an error. I am surprised that Adobe assigned this error to this problem. The solution is to simple start with Alpha characters, $(dollar sign) or _(underscore).

    package error_1084{
    }

    It looks like the last part of your comments didn’t make it. I would be happy to help with more info.
