[flexcoders] event propagation in FLex
I have one class that generates the event. I want another class to consume the event. How do I do this?

How do you prevent the app from confusing two events?

[flexcoders] Event Propagation Problem (I think)
Hello everyone, I am currently working on a set of time entry components that I hope to share with the open source community when finished. The components are a time masking field that extends TextInput, a TimeStepper extends NumericStepper, a DateTimeChooser extends DateChooser and DateTimeField extends DateField. My question concerns the TimeStepper and TimeField. When I set the focus to the time field by clicking on it and then clicking on either arrow button to increase or decrease the time, I get the following error. It should also be noted that the first version of NumericStepper that extended UIComponent did not have this problem. If anybody knows where and how to prevent the following stack trace, your help will be greatly appreciated. Also, I am curious to know if anyone would find these components useful in their own projects. Thank you in advance for any assistance, Orville TypeError: Error #1009: Cannot access a property or method of a null object reference. at mx.controls::TextInput/drawFocus()[E:\dev\3.0.x\frameworks\projects\fr amework\src\mx\controls\TextInput.as:1851] at mx.core::UIComponent/focusOutHandler()[E:\dev\3.0.x\frameworks\project s\framework\src\mx\core\UIComponent.as:8563] at mx.controls::TextInput/focusOutHandler()[E:\dev\3.0.x\frameworks\proje cts\framework\src\mx\controls\TextInput.as:2151] at flash.display::Stage/set focus() at mx.core::UITextField/setFocus()[E:\dev\3.0.x\frameworks\projects\frame work\src\mx\core\UITextField.as:1531] at com.m4tech.FlexLibraries.components::TimeInput/setFocus()[F:\Projects\ Flex\src\com\FlexLibraries\components\TimeInput.as:381] at com.m4tech.FlexLibraries.components::TimeStepper/buttonClickHandler()[ F:\Projects\Flex\src\com\FlexLibraries\components\TimeStepper.as:398]

Hum Very strange error, if you share you're code maybe will be easy to everyone help you. But try to debug and place a breakpoint where it's focus using event.preventDefault() to see what's happen behind the scenes.

[flexcoders] Event Propagation
How to implement this type of event propagation? My application component tree is roughly: App - main container - header container - menu component - body container - form component the user 'Saves' the entity in the form via the menu. I want to validate the form's required fields prior to the save, so the menu component fires an AppMenuEvent - doValidation event. The form component, which has registered for that event, never receives the event. I think this is because of the application component structure and specifically because the form component is not in the component tree from the event initiator (menu) to the App root node. Is that correct? How to resolve? thanks
RE: [flexcoders] Event Propagation
*directly* registered? As in: myMenu.addEventListener(doValidation,validateForm) Or are you counting on bubbling?

Hello yall... im trying to comunicate controls with events, these controls are in diferent HBoxes.(they have diferent fathers in the tree hierarchy), but the control that listen doesnt work properly. i've tryed to do so in the bubbling and capture phase but nothing... in a different approach i tryed to reach the root panel (successfully) and then from there dispatch a new event to all the childrens but no one seems to listen. any comments??
