As3 Error 1046
vote favorite The following code raises an ambiguous reference to value at compile time: import flash.display.Sprite; public class Main extends Sprite { private var _value : Number = 0.; public function get value() : Number { return _value; } private function set value(v : Number) : void { _value = v; } public function Main() : void { value = 42.; } } I suspect some kind of as3 error 1119 bug in the compiler, though I didn't actually read the ECMA standard. Before someone asks those questions: Private setters do make sense. The ambiguity also exists with custom namespaces (which is the problem I'm facing). actionscript-3 visibility setter getter share|improve this question asked Mar 24 '10 at 16:18 Warren Seine 854926 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted it is indeed a bug in the compiler, and it is listed in the bugs. its stated that its an oversite of the developers and wont be fixed any time soon. if you are needing to specifically run a function to set privately (rather than just assign the value, in which case you can leave out the setter function completely and itll run) then you will have to run a seperate function as Sandro said. share|improve this answer answered Mar 25 '10 at 7:59 longstaff 1,9711814 add a comment| up vote 1 down vote I think this may be a limitation of AS3. You could create a private function called setValue() or if your set on having a setter you might be able to get away with this, although it's not very pretty. package { import flash.display.Sprite; p

As3 Error 1034
The following is a list of compilation errors that the compiler generates when it encounters invalid code. A subset of these errors is detected only when compiling http://stackoverflow.com/questions/2509372/ambiguous-reference-when-getter-setter-have-different-visibilities code in strict mode. Strict mode adds three constraints not found in the standard language: Expressions have static types and type errors are verification errors. Additional verification rules catch common programming errors. Verification errors are reported ahead of time. These are the verification errors that occur only in strict mode: Function call signature http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/compilerErrors.html matching, which checks the number of parameters supplied and their types. Duplicate definition conflicts. Unbound references, which occur when accessing methods or properties that are not defined at compile time. Dynamically adding properties on sealed objects. Writing to constant variables. Deleting fixed properties. Comparison expressions that use incompatible types. Unfound packages.
CodeMessageDescription1000Ambiguous reference to %s. A reference might be to more than one item. For example, the following uses the namespaces rss and xml, each of which defines a different value for the hello() function. The trace(hello()) statement returns this error because it cannot determine which namespace to use. private namespace rss; private namespace xml; public function ErrorExamples() { use namespace rss; use namespace xml; trace(hello()); } rss function hello():String { return "hola"; } xml function hello():String { return "foo"; } Correct an ambiguous reference by making the reference specific. The following example uses the form namespace::function to specify which namespace to use: public function ErrorExamples() { trace(rss::hello()); trace(xml::hello()few months ago, I had already tried out various alternatives, among which the following (which was later also pointed out by others through the comments): [Bindable] // public getter: public function get http://www.rubenswieringa.com/blog/ambiguous-reference-bug-for-namespaces-in-flex someProperty ():String { return this._someProperty; } // protected setter: protected function set someProperty (value:String):void { this._someProperty = value; } However, the problem here was that Flex throws an error saying "1000: Ambiguous reference to someProperty" http://www.actionscript.org/forums/actionscript-3-0-a/209788-ambiguous-reference-class-error.html whenever you try to use the setter. After reading a post by Adam Flater I decided to start looking through the documentation and found out that this is in fact a known compiler bug: 174646: as3 error If a class contains accessor functions with different access control namespace attributes, (for example, aprotected setter and a public getter) using one of them causes a compile-time-error, for example,Compiler-Error 1000: Ambiguous reference to myVar The workaround is to rename your getter or setter function to avoid the mismatch. Common Flex 2 compiler errors and known issues This bug doesn't seem to have been fixed in any of the Flex 2 hotfixes, as3 error ambiguous and neither in the Flex 3 Beta (thanks to Wietse for testing). Let's hope the folks over at Adobe are going to do something about it..

First off, it's mostly the people that call AS3 an Object Oriented language. But mainly I disagree because your problem ("this simple pattern of having a property read-only except for derived classes is not supported") has little to do with a programming-language being Object Oriented or not. steve December 8, 2008 at 5:44 PM I'm coming from the .NET world and trying to learn Flex. Basic compiler bugs like this make it hard to take Flex seriously. Especially the fact that it hasn't been fixed and is over a year old. Thanks for article! April 1, 2010 at 2:32 PM The same thing is happening when we have base class with, for example, protected setter and getter. And we inherit this class. In inherited class we override, for example, getter. Then we have the same error. To fix this we need to override getter too. Comment navigation ← Older Com
