As ArrayCollection in Flex is limited, I'm looking for a data-structure that something like LinkedHashSet in Java, LinkedHashSet maintains a doubly-linked list running through all of its entries,it defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order).But there is little information about Flex data-structure

I'm coding a web app in flex blazeds and Java. I installed the Eclipse plugins for using WTP mixed project. I'm using flex's server that uses an emulate of tomcat when i ran my flex service the web app got the datas, everythings is ok. the problem is when i copy the project with all files generated by flex in my tomcat or the blazeds's tomcat, it doesn't work, this is becasue i want to implement my app on a server the error is:[code]
i don't know why tomcat doesn't find the class of flex.messaging.endpoints.AMFEndpoint that is used for my-amf 'URL...'. all works well in the emulated server that flex has.
I'm trying to integrate Seam and Flex with GraniteDS, with the goal of implemenenting a code generation tool for main use cases of CRUD operations.One of my needs is to have the possibility to generate a combo box to reference a parent entity from another. For example, a state combo box in my county edition/creation screen.

View 3 RepliesIn flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?
I have a java class which has been deployed as WAR web application in a BlazeDS/Spring server sitting on JBOSS. Apart from the Flex application which will access the WAR file, I also need to start some server side process's which will initiate BlazeDS "pushes" to the Flex client via AMF messaging.
What is the best way to implement this server side process? - Should it just be a class with a main() method in the WAR file which gets called from the command line? Can this be done - not sure you can run a class in a WAR file from command line? - Should it just be a class with a main() method in a JAR file which gets called from the command line? Not sure what the standard practise here is. The key is that the process needs to be started on the BlazeDS server to push data out (not on the Flex client).

View 1 RepliesYou can hook into the creation of Flex 4 item renderers easily enough (through itemRenderer, or itemRendererFunction) allowing you to pull renderers from a custom object pool, but how would you put those renderers back into the pool?
I understand that layout virtualization does a form of object pooling, but I'd like a way to hook in to that. For example, when an itemRendererFunction has been assigned to a data group with a virtualized layout, item renderer construction is indeed deferred, but the instances are not re-used - I'd like to be able to intervene there, if possible.
But even in the case of normal virtualized renderers (where the instances are re-cycled) it would still be useful to be able to manage the pool manually. Pools could be shared between data groups, for example, to reduce the initial buffer required to populate each group.
Is there any way to know when Flex discards an item renderer instance? I have a sinking feeling that there is just no reliable way to tell - even though perhaps there should be.
I'm on planning/modeling phase to develop a remote desktop sharing solution, which must be web browser based. In other words: an user will be able to see and interact with someone's remote desktop using his web-browser.Everything the user who wants to share his desktop will need, besides his browser, is installing an add-in, which he's going to be prompted about when necessary. The add-in is required since (afaik) no browser technology allows desktop control from an app running within the browser alone. The add-in installation process must be as simple and transparent as possible to the user (similar to AdobeConnectNow, in case anyone's acquainted with it).The user can share his desktop with lots of people at the same time, but concede desktop control to only one of them at a time(makes no sense being otherwise).
Project requirements:All technology employed must be open-source license compatible.Both front ends are going to be in flash (browser)Must work on Linux, Windows XP(and later) and MacOSX.Must work at least with IE7(and later) and Firefox3.0(and later).At the very least, once the sharer's stream hits the server from where it'll be broadcast, hereon it must be broadcasted in flv (so I'm thinking whether to do the encoding at the client's machine (the one sharing the desktop) or send it in some other format to the server and encode it there).Performance and scalability are important: It must be able to handle hundreds of dozens of users(one desktop sharer, the rest viewers)We'll definitely be using red5.My doubts concern mostly implementing the desktop publisher side (add-in and streamer):
1) Are you aware of other projects that I could look into for ideas? (I'm aware of bigbluebutton.org and code.URL...)
2) Should I base myself on VNC ?
3) Bearing in mind the need to have it working cross-platform, what language should I go with? (My team is very used with java and I have some knowledge of C/C++, but anything goes really).
I have a flex-application deployed on tomcat with blazeds. User constantly selects ranges excel-document. Now, a user enters a cell addresses in text fields (for example, C1: C20). But it is very inconvenient! How to display excel-data as a table in my application? I think, I can parse excel-document using Apach POI and transmit these data to the Flex-application. But there are other ways?
View 2 RepliesI'm developing a Flex front end client for a Java server application and I have a set of model classes that represent objects in my business logic and should have the same properties and exhibit the same behaviour throughout all layers. These objects
-Have form validation logic for user input
-Are displayed in various forms (lists, detail views ...) throughout the UI
-Are retrieved from and sent to the server using XML or AMF
-Are validated again on the server
-Are stored in a RDBM with tables and fields corresponding to the classes and fields
This is a very common application structure, I guess. I'm already using:
ORM for the Java backend (Eclipse persistence package)
Automatic mapping from XML to Action Script, using XML schema and the classes in mx.rpc.xml, as described here.
Now, what I'd really like to do is define the objects once (I already have them in XSD) and have tools set up class stubs for the whole chain. What can I use?
I've already heard of (but not evaluated):
XMLBeans to generate Java classes from XML Schema
Granite DS to generate AS classes from Java classes
I want to analyse if the XML I send from my client Flex to my Java using remoteObject is compressed or not. for this, I'm using Wireshark, but it can't get packets in the localhost (windows vista)

I have been working on a flex application with java, as i have used Life Cycle Data Service for communication, i wana know, is there any function of flex, where i can see the loading status in percentage, that how much record is being loaded.Problem is, if there is lengthy record, no body comes to know, whats happening with software, like in Comboboxes or Grids, users usually think it as a BUG in application, but ofcourse it is not.I need such graphical loader, which keeps on loading with proper status in percentage, until it receives all data from JAVA (SQL Server).

I'm sending through a socket from java to flex client some data and the flex side can't seem to handle it right. In the java i'm looping over 8 objects and for each object I create a long string 1:lsls:2:3:justexample then the java does writeToSocket("1:lsls:2:3:justexample") for every iteration of the loop. But in the client side, it seems that only 2 out of the 8 arrived. what can be the problem?
View 1 RepliesI am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want?

View 1 RepliesWe are in the middle to evaluate the technology choice to re-design an operator console application. The operator console as a hosted contact center has the abilities to queue the inactive calls, and hold, answer, transfer the active calls.
The legacy operator console used Java Swing. We want to use the latest RIA technology (Flex/Silverlight) to retire the legacy one. But the question is Flex/Silverlight can implement the functions like hold, transfer the calls? Based on my experiences, Flex can listen Java socket to receive XML data? Does it work well to receive voice data?
I have a server with some simple java objects running. I want to build the client with Flex and connect to the server data with BlazeDS. The problem is the Flash Builder is not generating the Classes correctly. Just the properties are being generated, the inheritance are not being generates.

I was just wondering what the best data structure would be to use to represent data objects in a side scrolling game, basically the stuff the user can't see isn't on the stage so I would generally create a custom class to define its properties (x,y,weight,type, derp, etc) and then push that into an array and as the user moves forward I project the info from the array while checking if their x position is.
The problem that can occur is that the user can move left and right so whats the best way to keep track of the indexes?
