Flex :: Populating ArrayCollection With HTTPService?
Jul 14, 2009
I am creating a RSS Feed application based on a data, and I have the following:
I have an ArrayCollection that is pre-populated with data. I am sorting through the ArrayCollection, get 1 piece of data (condition), and need to connect to an RSS feed which returns me the title, and I set my ArrayCollection in correspondence to condition -> title.
public function updateArrayList(list:ArrayCollection):ArrayCollection {
trace(list);
for(var i:int = 0; i < list.length; i++) {
//Alert.show(list.getItemAt(i).condition);
I am passing a complex object from my .NET library to my Flex application via WebOrb.In order to automatically translate, I am using the [RemoteClass] meta data tag as follows:[code]This works absolutely fine, until I try to extend the Plan class to contain an array of complex items:[code]but the set function never gets called.What can I do to get the children into my Flex app in this way?
I want to load data from a external XML file, using a HTTPService, and on the ResultEvent of the same HTTPService i want him to populate a ArrayCollection with the data from the XML.
I think a ArrayCollection is the ideal for this XML.
I am passing a complex object from my .NET library to my Flex application via WebOrb. In order to automatically translate, I am using the [RemoteClass] meta data tag as follows:
ActionScript Code: [RemoteClass(alias="test.PlanVO")] public class Plan {
[Code].....
but the set function never gets called.
What can I do to get the children into my Flex app in this way?
When I tried to populate an arraycollection dynamically its saying no values found. Code that I used for this is given below: [Bindable] private var myARR:ArrayCollection=new ArrayCollection(); private function abc(){ var myStr:String="{year:'2004',Test1:10,Test2:20,Test3 :30}"; myArr.addItem(myStr); }
I am having problem when i get only one row from httpservice.
I am using this to fill the arraycollection:
ActionScript Code: public var arrColl :ArrayCollection; private function listResult(e:ResultEvent):void
[ode]....
When i have more than one row everything is ok but when http service return me just one row this just won't work and var arrColl is not populated so my datagrid is not showing anything.
I have created a simple method to retrieve XML output from an HTTPService and populate a database from it, but due to the async nature of Flex, the functions go through while its still retrieving data - hence causing the function to return a null value. find code below;
I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
where the component before / represents parent and the children of the corresponding parent are separated by , Can anyone provide me the logic to create a array collection for this hierarchy to set as dataprovider to my tree.
In the below code.If buttom 'A' is pressed the text box should be populated with A, and if button 'B' is pressed it should be populated with B and so on..
What is the best way to populate a multiple Comboboxes when using Flex 4.5 and PHP 5?
I am developing a Flex app that displays about 20 Comboboxes on the screen - each combo showing different data. I would like all of the comboboxes to be populated at once when the app starts. I used the default "Data/Service" wizard in Flex that automatically creates the PHP that returns an ArrayCollection to Flex. For example, below is the current PHP function I use that populates each ComboBox:
public function getListsByCODE($code) { $stmt = mysqli_prepare($this->connection, "SELECT a.IDCODE, a.CODE, a.DESCR, a.NOTES FROM DROPDOWN_VW a WHERE (a.CODE = ?)"); $this->throwExceptionOnError();
I'm having a problem displaying data from a function to text box within a tab. If you run the code and click "Select Tab 2 and Fill..." I get an error; "TypeError: Error #1009: Cannot access a property or method of a null object reference." I'm guessing this is because "Tab 2" is/was not rendered yet. Now if I run the code, select "Tab 2" then select "Tab 1" and click "Select Tab 2 and Fill..." it works the way I would like. Dose any one know a way around this problem.
I only need the Title and Updated fields to actually be loaded into the DataGrid. This clearly doesn't work, (I think it's related to result.entry, that it must be something else like result.feed.entry, but I've tried a number of combinations and they haven't worked
I'm having trouble getting an AdvancedDataGrid to populate properly within an app I'm working on.If I use the sample code found on this page http:[url].... in it's own page everything works fine but if I copy this code into the page within my app that needs to have the grid the column headers/data are not populated.The page that needs the grid is displayed within a Spark NavigatorContent element, I'm not sure if this could somehow adversely effect the AdvancedDataGrid behaviour.I've even simplified the contained page to have just the sample code without anything else and it still does not work. info needed here,
EDIT: Some code sample from the project:
//Code from 'main page' containing the NavigatorContent <mx:ViewStack id="viewstack1" cornerRadius="12" dropShadowVisible="false"> <s:NavigatorContent label="Matrix View" backgroundColor="#FFFFFF">[code]...............
In ActionScript I have string as str="subject,r1,r2:a,b:1,2:3,4"; Dynamically I have split this string and build array collection as given below arraycoll.addItem({subject:a ,r1:1,r2:3}); This example of one set. The array collection should be built dynamic. I have tried but not successful.
I have a Flex client making RESTful calls to a webservice using HTTPService. The server is returning JSON responses, which we would like to compress. Can Flex using HTTPService handle gzip-encoded responses? If so, what steps are required to make it work (e.g., which headers to set, how to decompress, etc.)? If not, can you suggest a simple alternative?
I have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
I'm trying to reuse the HTTPService object in a flex app but I'm running into a problem. In the handler for ResultEvent.RESULT I'm removing the listener, but it isn't removed. I've have to catch the asyncToken from send() and attach a new property so I know what it's supposed to do in the handler.URL...You can right-click and view source.Has anyone else run into an issue where listeners aren't removed? Should HTTPService not be reused?
How can I set a progress bar that may start when an HTTPService is sent and stop when the HTTPService ends?I followed code given here but encountered following error Type was not found or was not acompile-time constant: ProgressWin.Don't know whether ProgressWin.mxml is a component or module or what. I just created a new ProgressWin.mxml file and pasted the code you posted but following error popped out before
XML is cool in flex, but I have an annoying problem to solve, caused by what I can imagine is a feature. You see, when you have just one tag of something, it creates an object which is not an array. But when finds more than one, it puts it on an array structure.[code]I could check the format of resObj.specifictag (to check if it is has an array) and then duplicate the code (for each case). But -even if it's calling a function- I don't think it is an elegant solution.Well, I hope someone has a good idea on this matter. (I know from experience that SO has much more C++ experts than flex, but well...)The perfect thing would be that HTTPrequest handled every tag in a consistent way (using always arrays... though I'm guessing that that would also have its drawbacks).
Why are there two different HTTPService classes in Flex?thisandthisAnd the second one inherits the first one.Why couldn't there be a single class combining the two?
I am using an HTTPService in my Flex application. I want to load several xml files, each about 1mb in size. Sometimes I need to stop loading previous xml file and start loading a new one. If I use HTTPService.cancel(); or HTTPService.disconnect() , it increase the time to get the answer from the server.Is there a quick way to stop the previous loading in HTTPService and start new one?
I am trying to figure out how to manage a Datagrid based on an XML object like this:
[Code]...
I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates.
I am trying to create an desktop app where the user selects an XML doc via a FileSystemTree. Then at the click of a button, that xml doc selected will be loaded in as the XML doc of choice. So far I have it working only if i hardcode in the path, but i need to make it so that the user can select the file dynamically.
I'm getting occasional ConcurrencyError faults when using HTTPService in Flex 3. I have four HTTPService objects, all configured with concurrency=single. I'm not sure though how to continue to diagnose, as I don't see in the FaultEvent what service object caused the issue, and I can't easily reproduce it on-demand.
One feature of my app is that I am also using a URLRequest to load a sound shortly after receiving a result from one of the HTTPService calls. Could this be related to the concurrency error?
The fault looks like this:
[FaultEvent fault=[RPC Fault faultString="Attempt to invoke while another call is pending. Either change concurrency options or avoid multiple calls." faultCode="ConcurrencyError" faultDetail="null"] messageId=null type="fault" bubbles=false cancelable=true eventPhase=2]
I am developing an AIR application with Flex Builder that requires me to make two HTTPService requests at the same time. They both use different instances of the HTTPService AS3 class. Both services are calling a RESTful API which is currently running on my localhost (XAMPP) and takes a few seconds to respond (much quicker on live server). The problem is that most of the time one of the calls fails, however occasionally they do both work. Its also random as to which call will fail. Both calls use code something like this. This code is basically repeated in two classes.
I am new to Flex (FLex Builder 3.0), and I'm creating a simple application that would basically just authenticate to the Freshbooks API (www.freshbooks.com) via HTTPS. without sending anything else.
[Code]...
How do I code it such that the username (the authentication token given by freshbooks) would be sent to the server from within Flex itself and not the browser? My expected outcome is that there would be no pop-ups from the browser and whatever the freshbooks server returned would be displayed in the text area (txtArea1).
Note: If I input the authentication token to the browser pop-up, the application is able to correctly display the output to the text area.
