I'm in a Flex Mobile application project. I need to dispatch an event to the lexGlobals.topLevelApplication and it has to contain a custom message. I'm trying to make an object and dispatch it like this:
//create the event Object
var receivedObjMsg:Object = new Object();
receivedObjMsg.name = "receivedMessage";
receivedObjMsg.message = messagevarhere;

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event
package events
{
import flash.events.Event;
import ui.map.MapElement;

How to trigger a custom jQuery event from Flash, passing some data through event object?
View 2 RepliesMy prog here doesn't work there's no syntax error My flash custom event doesn't trigger
so my question is can flash object dispatch custom event to itself because that's what I wanna do ?
I have searched on the Internet and didn't find any clue on how to do so, any idea ? I don't want flex only flash (my objects are not visual components).
View 3 RepliesI want to listen for a custom event dispatched from the document class in a custom subclass. For example, let's say in the document class I have:
ActionScript Code:[code]....
So that the subclass will trace 'Event from document class received' when the 'customEvent' event from the document class is listened by the eventlistener. However, the output is only 'customEvent dispatched', meaning it wasn't heard in the subclass.
I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
I hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void

I have a custom Flex 4.5 component (to be used in a List) -

But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.

I made a movieclip in flash that dispatches a custom event: MyEvent.THE_TYPE = "the_type"in flex I have: <local:my_flash_mc the_type="do_something()"however, this is not working.in flash, my event bubbles is set to true. everything works fine in flash.in flex I am NOT using:

I am trying to understand event propagation in Flex framework and have a following doubt on it:
Scenario: I have a built-in component DropDownList on change of which I want to create a custom event refreshPreview and want to propagate it to a custom component PictureComponent.
In the custom component's mxml, I have added the Metadata directive as follows to register a refreshPreview event with the compiler
<fx:Metadata>
[Event(name="refreshPreview", type="flash.events.Event")]
</fx:Metadata>
Layout Details: In my main mxml application I have laid out DropDownList and the custom component such that both are siblings (i.e. have a common indirect parent)
e.g.
<s:Group id="contentGroup">
<s:Group id="formGroup">
<s:Form x="11"
[Code]....
I am seeing that the refreshPreview event is not getting propagated to the custom component.
I doubt this is because the built-in component is a sibling of the target (where the event got generated) and not a parent. how to make refreshPreview event propagate to custom component?
printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI have a utility class that I use to load images that never gets added to the stage and is extending EventDispatcher, it simply loads the data and spits it back out on request.
I want to add a custom event to track loading progress from outside the class. The events are firing but not (i think) bubbling because they aren't in the display list.
Is there a good way around this? I was thinking: Can I have a non display list object tell a display object to send the custom event for it?
I'm trying to make a custom event that bubbles up from the Items object in this code to the Main object, and start the changeInfoHandler there. For some reason, it works when I put the dispatchEvent in the Items object inside a handler for a mouse click, but when I try to bypass that and call the function directly, it seems to only work in the scope of the Items object.

Code:
package{
import flash.display.*;

how to dispatch custom event in flex in my main mxml file i have put this code to dispatch this function
[Code]....
i want to ask what i am missing why my customevents not working
I got a question about event dispatching in flex.my goal is to get a custom event loaded up with some data and than bubble up to the eventlistener. my main application has and AMF service request inside which calls an service class. that class is supposed to dispatch an event when the AMF service request returns a result or fault and the main application is listening for that event.so inside my mainapp i add and listener like this:[code]
However, this event never reaches the main application. Looking closely to it with the debugger, i found out that when the event is dispatched the listeners property of it is set to null.
I'm trying to dispatch a custom event from a custom ItemRenderer. This is my custom event

The event from the function is dispatched correctly... I can't intercept it..
I created a new CustomEvents object which I want to use to let the main class located in .mxml file to know about an event which had finished it's work in Crop class. However when I dispatch a CustomEvent from Crop class I can not catch it in my main .mxml file's class.

I have 2 custom components, which have their own nesting hierarchy ... One is container for another. I have to "familiarize them" with each other. The way I'm trying to achieve that is using global events (one side is firing and the other one is catching):
Application.application.addEventListener("Hello", function (data:Event):void{
// .. some actions
});
[Code]...
Then should be created the connection between container and it's child.
BUT, the only thing I could acheive is passing a reference to the Container in the DynamicEvent. Is there any chance that I could access the child at the event-handler function.
