I'm trying to set the previousClip variable (which belongs to the Scratch-class) in the onMouseUp function. I know I'm not doing it the right way, but can someone tell me how to set a the previousClip variable properly?
The following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

A Flex components values are initlized by init methord. In an application flow, How to refresh a mxml component data value ; as init is callled at the start up it self only.

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

how ( if it is ) to check the device type with flex ?
with device type i mean : PC, laptop, tablet, phone ..
Should I do it like this:
if (DeviceDisplay.IsSpeedAvailable == false){
DeviceDisplay.IsSpeedAvailable = true;
}
or
DeviceDisplay.IsSpeedAvailable = true;
I thought I saw that flex/as3 does an internal check on booleans before they are assigned to make sure you are re-assigning stuff but I can't find it to confirm.
