I want to iterate over an ArrayCollection in Flex while there can be items added and removed.
Since i didn't find a way to use a "classic" Iterator like in Java, which would do the job. I tried the Cursor. But it doesn't really work the way i want it to be ;) So how do I do it nicely ?
var cursor:IViewCursor = workingStack.createCursor();
while (!cursor.afterLast)

I am using Adobe Flash Builder 4 Premium. I have a mx:DataGrid and a s:TextInput, and I am trying to set up a search box that filters the DataGrid on each key press.his page shows a nearly perfect example of what I'm trying to do, except that I'm setting this up in a s:TitleWindow, which is brought up as a popup using the PopUpManager. The list I'm trying to filter can be very large. It is a list of usernames, fetched from a MySQL database via PHP. Since it can be so large, I want the list to be populated once in the main application and then referenced in the popup window so that it doesn't have to fetch all the usernames each time the user opens the popup.I have all of this working fine for the first time you bring up the popup, but if you close it and bring it up again, I get this runtime error:I also get this error if I attempt to set the filterFunction back to null just before closing the popup.See sample code below:
Main Application:

I have an arrayCollection with the following structure:
[Code]...
the AC is defined as follows:[Bindable] private var projectErrorsAC:ArrayCollection = new ArrayCollection;
I'm using this AC in a repeater to display each error. After each error is shown, I've placed an "Accept" and "Deny" button. Once the user clicks either one of these buttons, I'd like to call a function that removes the particular error from the AC. Here's what I have so far:

I have an ArrayCollection that is the dataProvider for a spark.components.List, which has allowMultipleSelection="true". There is a "Remove Selected Items" button which initiates the removal of all the selected items from the ArrayCollection upon being clicked.
I currently use the following method:
myList.selectedIndices.sort(ascendingSort);
// remove items, counting backwards
for (var i:uint = myList.selectedIndices.length; i > 0; i--) {
myArrayCollection.removeItemAt(myList.selectedIndices[i-1]);
}
where ascendingSort does what you expect ;). It works fine, and I know that it will always work.
However, I did take note that if I neglected the sort altogether, to my surprise the removal still worked. The reason for this turned out to be that, when the removeItemAt is called, the selectedIndices are correspondingly updated.
So my question is: Can one rely upon a removeItemAt call updating the values in the selectedIndices? or might that turn out to be different between runtimes and/or Flex SDK versions?
I am trying to swap two items in an ArrayCollection with this code.
[Code]...
When debugging the code I can see that curItem and swapItem are the correct objects, but when I do my first setItemAt, it replaces the one I wanted but also one that I didnt want.
After applying a numeric sort to my dataprovider(Array Collection), I can not reorder the items via a tilelist. Do I need to remove the sort from the arrayCollection. If so, is it just a case of setting collection.sort = null ?
var sortField:SortField=new SortField();
sortField.name="order";
sortField.numeric=true;
var sort:Sort=new Sort();
sort.fields=[sortField];
I'm making a very short text adventure, not one that will be all that fun, but just so I can learn a little as3. So I was designing a system that splits the persons input into an array of words, and then goes through and takes out unimportant words like "on." To test this out, I quickly (and messily) coded it up, and the only thing you can do is sit on a box. but it doesn't seem to be working. if you type "sit box" it works, but "sit on box" does not.

I have a small problem with iterating over array. I would like to iterate through items gathered in my array in a way of "one at a time" in each muse click event but whenever I'm using a simple loop it just takes all my elements to process. Is there a way to make a single iteration in each click and still increment the index value in loop?

im having some dificulties in the combobox of Flex 3, after defining the dataProvider and filling the combobox, how can i remove the items in the combobox later (without removing items in the dataprovider)? if i set the provider to "" or null, the items in the combobox are still there
View 1 RepliesI am new to Flex. What I am looking for here is adding a click handler on all the items created by a SkinnableDataContainer. I tried several things that didn't work, and I have no idea what is the right way to do it.
<s:SkinnableDataContainer id="teamList" itemRenderer="TeamSummaryRenderer">
<s:dataProvider><s:ArrayList>
<fx:Object teamName="A super team 1"/>
<fx:Object teamName="A super team 2"/>
<fx:Object teamName="A super team 3"/>
</s:ArrayList></s:dataProvider>
</s:SkinnableDataContainer>
Furthermore, I don't want to declare the handler in my custom TeamSummaryRenderer component. I would prefer that the handler code stays at application level.
I have s:list component in my MXML and a different actionsscript file which does the socket connection to the server.Everytime a user is connecting to the server I'm sending to all clients the updated users in the server by sending strings of ports (port for each user).Now, when the data gets to the client (to the action script file SocketData function), I want it to be added as an item to the s:List in the MXML file.

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:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
<mx:Script>

I am having issues with this method. It's supposed to loop through stage elements (news feed) and check if the item is checked/enabled. If they are, it should add them into an array ratingAC, which will keep track of the number of elements that are rated, and the rating total. The problem I am having is that only one item is added to the total even if multiple are selected.

View 1 RepliesBelow is a function set that's used to get info from an XML source(s) and populate a List Component (videoList). Works great. The second function loads data from a separate XML source and populates the SAME List Component. When the second function is called it loads the data in addition to the existing data into the List Component. I want it to REPLACE the data. How would I accomplish this?

I have a Listbox whith a ArrayCollection as datasource. I'm trying to remove the selected items from the ArrayCollection to update the list.Here is how I coded the remove function:
for each (var item:Item in theList.selectedItems)
{
theArrayCollection.removeItemAt(theArrayCollection .getItemIndex(item));
}
This works fine as long as the ArrayCollection is not sorted. When I apply a sort I get a RangeError from ListCollectionView.removeItemAt.
I could pop, shift, splice or slice it out of there (hey, that had a nice ring to it...)

View 1 RepliesI am using a service that returns JSON (geonames.org) and I'm putting the result in an array and dumping it to a datagrid. Now that works fine for one city like this [URL].. However, I want to call this service multiple times with different city names, so I created an XML list ad figured I would iterate over the city list and get the results.
My question is how do I do this such that 1) all the lists are combined into one arraycollection and 2) this seems like I will have to chain the calls and wait for results which may or may not come back, so I thought I would ask the group about the best practice, and or resources to read and examples to build from.
I would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.

View 2 RepliesI'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?
