Flex :: Unable To Bind Warning: Class Is Not An IEventDispatcher?
Apr 7, 2011
I am getting the error: warning: unable to bind to property 'Description' on class 'Object' (class is not an IEventDispatcher)
this is only when the data is bound to a List as an ArrayList, though. I had it in a Datagrid before (just as an Array) and it did not cause any issue. I'm not expecting to be able to bind any data back to the class 'object' not even sure which object exactly it's referring to.
My list data-provider is an ArrayList.. populated by a result event from an SQL query contained in another class:
private function loadDayComplete():void
{
var Meals:Array = _day.MealResults;
[Code].....
The day class I have is a data holder to get all the data (from several tables) for a 24 hour span.. I have classes for each individual datatype for editing them. But I'm not sure do I even need to worry about the warning if I don't plan on editing the values? it completely spams the console though whenever I touch anything, so I really would like to get rid of it. I tried an object proxy as I saw described elsewhere but nothing changed. The text is in label fields right now anyway, which can't even be edited.
i am using xmllistcollection for displaying data in list. whenever i run my application data is display in list control, but this warning has displayed in console. How can i remove this warning warning: unable to bind to property 'xmlnode' on class 'XML' (class is not an IEventDispatcher)
I've got an object that contains a dozen or so fields I want to bind to form elements, so that I can use that object to send the data back to the server to be saved.
In my Flex app I am using a repeater to show a report on my database data. On this report the user can "drill-down" on the data to show more detail. In order to make this easier on the eye I have a header label and then a datagrid within the repeater.Whilst this works perfectly, because the dataprovider for the datagrid comes from an array in the repeaters dataprovider, it is causing the following warning:Data binding will not be able to detect assignments to "report"The warning is for this line:
Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)
I work with Flash Pro allmost 11 hours per day and every while i get a error which messes up everything. Approximetly i get this after about 2-3 hours withevery project.After i get this error there is no chance to test movies afterwards.I see a fast flash of the loader window but it dissapears so fast i cant even really see if it is loader.
Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.
Here the method clientMonitor() is called on creationcomplete() from the main application.
I am not able to bind the Bindable variable dbl to my textInput. Using the debugger, I am able to see that the result is assigned successfully to variable dbl, but it is not able to bind it to the text of view1. I see a NaN displayed in the text of view1.
It's coming from this line of code:var dropTargetXML:XML = XMLTemplate.template.component.section.question.(@question_questionID == nNode.parent().@question_questionID)[0];nNode is an XML node sent as an argument to the function this is called in. The code runs,and does everything expected but the compiler sends out that warning. Do I have some formatting issue?P.S. I've tried telling it that it's XML like this:var dropTargetXML:XML = XMLTemplate.template.component.section.question.(@question_questionID == XML(nNode).parent().@question_questionID)[0];
Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
I'm a very new user to AS3 and I'm attempting to migrate a site from Flash CS3 to CS4 on a Mac. I keep getting the following compile warning: "Warning: Actions on button or movie clip instances are not supported in Action Script 3. All scripts on object instances will be ignored." This is very confusing to me. I thought that scripts could be attached to both frames and objects? Is this a bug that is a result of switching from versions? Or is this warning true; and I have to abandon all uses of attaching scripts to objects on the stage?
Also: Can anyone illuminate me on the keystroke to call the actions window in AS3? It is supposed to be the F9 function key and another that I can;t locate on my keyboard!? As I said,I'm a very new user, so be kind!!
I just recently been using a lot of prototype javascript stuff, and was wondering there was anything like the "bind" method, for use in AS3. It's proved quite useful to be able to look both at the event.target as well as the class object the handler function might be associated with.
I've been experimenting with Senocular's Transformation Tool, and keep getting this warning at Line 1309 of the Transformation Tool Class version 0.9.11:
Warning: 3553: Function value used where type Boolean was expected. Possibly the parentheses () are missing after this function reference. Line 1309: if (interactionMethod && _transformTool.currentControl == this) {
I just commented out the line and put: if (_transformTool.currentControl == this) { And the swf runs fine.
I have a class with constructor and overloaded methods in it. When i try to import that class using blazeds i get an error saying [RPC Fault faultString="Unable to create a new instance of type 'some class'." faultCode="Server.ResourceUnavailable" faultDetail="Types cannot be instantiated without a public, no arguments constructor."] How to import class having overloaded methods using blazeds
I did suppress warnings in flex compiler using "-show-binding-warnings=false". But what I am interested to achieve is to suppress run time warnings (especially binding warnings - since I am getting data in model mostly in XML structures and it is fine for me if its unable to bind to its nested child nodes) in console (I am working on flex on Eclipse with the flex plug in). Is there a way to achieve it?
The problem with flex applications is that a user can download it and run it on his local machine or possibly host it on another site. Is it possible to lock a flex application to a domain name to prevent such acts?
In my library I have:A Sprite named Emily of base-class "Character" with a sub-sprite labeled "head" of auto-generated Class "EmilyHead".A Sprite named Jess of base-class "Character" witha sub-sprite labeled "head" of auto-generated Class "JessHead".
Flash compiles with the following warning: Warning: All instances named 'head' will be automatically declared as JessHead in symbols that use Character as their base class. In symbols that are linked to user-defined base classes, instances with the same name must be of the same type. And then the runtime error:TypeError: Error #1034: Type Coercion failed: cannot convert EmilyHead@3a0d1e81 to JessHead. at flash.display::Sprite/constructChildren() at flash.display::Sprite()at Character() I can turn of auto-declare stage instances in the Actionscript 3 panel, but then I have to manually add a public var for all sub-child's, such as the head sprite. But then at least everything works as expected. This is more setup than I'd prefer to do, but everything else about this workflow is very fast & easy. What can I do to sidestep this error, while keeping the same workflow?
I am having a table at the backend, so when a query is asked at the frontend for an object, all the tabs in the front end should be populated with the details of the query object. I am able to pick the query object at the back end , but i dont know how to bind that object across all the tabs in flex. I am getting an error type coercion failed, cannot convert X to mx:Array collection
When the XMLListCollection is updated in the DataGrid, I want it to add the XML (bind it) into the Model. How would I do this? Or if not possible, how would I manually add XML into the Model?
This is a rough example of what I'm trying to do. Adding data to the DataGrid works fine; it just doesn't go into the Model when sending to the HTTPService.
I haven't used the implements keyword before, and I've been trying to use it to implement the IEventDispatcher class to see if this would allow me to use addEventListener() in a class that extends Object (this is my understanding of what it's for - correct me if I'm wrong).My class is like this:
Usually when I run my application Flex Builder creates a file in a directory on my local PC and then opens a browser and points to it. Everything was fine, but when I decided to link django server to flex applications via xml data providers I started to get security errors. (Related to absence of crossdomain.xml). When I created the file and put it on the server[code]...
I'm fetching some data from a PHP application using Zend AMF. However I can't get the data to bind to a simple DropDownList control. The PHP method is:
I am trying to bind a datagrid item to a combox, so that when the user selects the item in the datagrid the form displays the selected data for editing, however one of my items is a combobox using a dataprovider.
I would like the item selected in the datagrid to match the selected item in the combobox, this part is fine however if my datagrid item is null then I cannot get the combox to set the selected index to -1?(the same happens if you use the CRUD wizard in Flex builder 3 for ColdFusion)I am using the following code for my custom combobox:
warning: unable to bind to property 'image' on class 'XML' (class is not an IEventDispatcher)Is there a way I can turn off this type of warning (but keep the others) as it is driving me crazy when I try to trace something else.
