In Flex, how do you best manage child collection property changes, specifically notifying a parent object that a property within the child collection has changed.
package
{
[Bindable]
public class Author
[Code]....
How can I notify the Author when a Book propery has changed and update the dateOfFirstBookPublished method?
How can I populate multiple datagrids in flex with a single datasource that is filtered differently for each datagrid. I'm assigning the event.result from my remote object call to three different array collections, each with its own filter function. When I assign and refresh the filter functions, they each affect all array collections. So, the results of the last array collection refresh end up in all three datagrids.

i have a question while reading Flex 4 Cookbook i came across the method to dynamically adding control to the container controls but nowhere i came across with how to provide them with the dynamic properties and events like they have created a button dynamically inside a group control but what good a button be if i cannot give it an event dynamically. in the same way i want to add a tree view inside a vbox but what good that be if cannot provide a data provider to it dynamically.actually i am creating an web application where i add the tree view to a vbox and i want to the data provider should also be dynamic depending upon the option i have selected in the combo box.

In our project implementation we are passing ArrayCollection back to Java from Flex. And we are getting exception "sying blazeds cannot create class mx.collections.ArrayCollection"
This problem is coming when using BlazeDS 4 and Spring 3 at Java side.
I have some code that adds a child using addChild(dragsquare); dragsquare is what I used as the class for a movieclip, mcsquare.
Everytime a child is added to the stage, it is called: ObjectX The "X" increments everytime a new object is added using ++objNum.
E.g:
Object1
Object2
Object3
etc...
When the child is added to the stage, it can be dragged, resized, rotated, etc...
I have used this code so when someone clicks the "save" button it loops through all objects on stage (increasing the last number by 1 to get the next object) and finding their properties. Here is the code I have used.
ActionScript Code:
Code:
save.addEventListener(MouseEvent.MOUSE_UP, saveObjects);
function saveObjects(event:MouseEvent):void {
for (var i:uint=0; i<numChildren-23; i++) {
[Code]....
23 children already exist on stage so I have to minus that number to get whatever is added on stage by the user.
However, scaleX is getting the childs ORIGINAL properties and not its current stage properties (where it has been resized, rotated etc..) and only returns a 1 for scaleX. How would I make it track the properties it has on stage?
Basically, I have a menu created using XML. Each menu item has a fill that fades in and out as the user scrolls over them. What I want to happen is that when an item is clicked, it stays highlighted. The problem comes when I click on the second item. I can't get the first item to "unselect."Here is the menu code and functions.
Code:
var menuHolder:MovieClip = new MovieClip();
menuHolder.x = myMask.x;

I have a holder movieclip on screen, then I create a loader, load an external SWF into the loader and addChild to my holder:
var bgloader1:Loader = new Loader(); [code].....
This all works. Now if I want to come back later on and alter the alpha or position I get an error:
//Neither of these work: MyHolder1.bgloader1.alpha=0; MyHolder1.bgloader1.content.alpha=0;

I have created a loop to instantiate tiles on a board. In the following example, "Gametiles" is an array containing objects of class "Tile" which is a class that extends MovieClip. "Game" is a MC that I added to the stage in the flash developing environment.[code]This method is a bit cumbersome though. I really don't want to have to create a var and call getChildByName every time I want to interact with these properties or methods. How can I set up these children so that I can access them directly without the extra steps?
View 1 RepliesIs there a way for the child of a movieclip object to not inherit the paren'ts properties? Because I scaled down the parent movieclip height and width and I'm loading external images into the parent movieclip and images are also scaled as well so I'm wondering if there is a way for it not to inherit the properties but remain inside the parent?
View 1 RepliesMy player movie clip has a smaller movieclip within it. Because the smaller movieclip is not within the parent clip it changes the x,y,width,and height value of the player movieclip and throwing everything off! To adjust I have to add (-2ndmovieclip.height) to everything i want to do. This is sloppy and I don't like it. Is there a better way to have a child within a movieclip without it affecting the parents properties? i want the parent to keep its original x,y,width,and height properties but the child keeps adding to them!

I have an Flex-Object with for example 3 properties.
myObj.prop1
myObj.prop2
myObj.prop3
I like to generate 3 Comboboxes to show the data.
No problem if I do it hardcoded in sourcecode.
But how can I find the prop1 to prop3 at runtime?
If next time I have 5 properties with different name it should generate 5 combos.

The searches that I did on this topic aren't providing me with any answers...that I can understand anyway. =*) Here's the situation.In the past, I did computer-based-training using "a different authoring tool." One thing I discovered I could do with that tool--which really opened up new possibilities for me--was to use that scripting language to create a snapshot of the current window and save that image as an object/class. Then I could access that object, resize it, save it to disk, and load it in later. The result--for my training at least--was a visual bookmark of their location in the training should they have to save and come back later.I would now like to do this with Flash.specificially CS4 and AS3.If anyone can point me in the right location to get started,For clarity, the steps are:
1: Take a snapshot of the current Flash window / Stage. I'm not concerned if the snapshot remains "in Flash" or goes to the Clipboard as long as I can get to it in the next step.
2: Access that snapshot from where-ever it's stored.
3: Process the snapshot and reduce it to a thumbnail, etc.
4: Save it to a file that I can bring back into the .swf at a later point. I'm not real concerned about the format of the file as long as I can bring it back in later. How do I save it? I would love to be able to save it to the user's machine but last I checked
Flash won't do that sort of thing. Can I save it as a file on the server that the .swf is running from using perhaps a PHP call /script / page?
5: And, of course, recall the image to be used at a later point. I already have a pretty good handle on this from past experiments.
Does anyone know the name of the event that is dispatch by the attachCamera(), i would like to take a picture ones the camera is loaded, i try to execute my code after call attachCamera but it takes the VideoDisplay empty, that's why i would like to know if there is an event triggered after the attachcamera() is complete loeaded.
