Flex :: Length Of Filtered ArrayCollection?
Nov 19, 2010I need to display the number of items in a List component that has a filtered ArrayCollection as its data provider. I don't see a way to get the filtered collection's length.

Flex :: ArrayCollection - Filtered Out Images Vanish Suddenly
Dec 16, 2009I am working in Flex. I have an arraycollection which is used to fill a tilelist with images. I am using filter method of arraycollection to filter out certain images from tilelist based on a selected value from combobox. The issue is that when the images are filtered out they just vanish suddenly. But I want to give some effect to them when they are filtered out, say slow fade effect or zoom effect. I tried removedEffect, hideEffect etc. but in vain.
View 1 RepliesFlex :: Merge Data Into Filtered ArrayCollection (maybe By Using IViewCursor Or LocalIndex)?
Jan 5, 2012how do you merge data (coming repeatedly from server) into a filtered ArrayCollection?
The TestCase.mxml (just place it into a Flash Builder 4.6 project):
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark">
[code]....
The problem lies in the fact, that when the ArrayCollection _data is filtered (because the Checkbox "Even" is set), then the 2nd loop in the test case (for adding new items) adds items (the "35") again and again - because it's filtered and thus not visible.
Actionscript 3 :: Remove Filtered Out Elements From ArrayCollection?
Sep 4, 2011I have a big ArrayCollection variable. I want to filter it serveral times and each time assign the filtered result to a different ArrayCollection variable.
So if it has let's say people, fruits and cars. (for illustration purposes) I want to first filter it to only show people, assign the result to a people ArrayCollection, then filter it to show fruits and assign it to a fruits ArrayCollection and so on.
How can I do that? Not the filtering, but the assignment after filtering. Or is it faster to instead run a for-loop through the big ArrayCollection and just add each item into the corresponding smaller ArrayCollection?
Actionscript 3 :: Watching An ArrayCollection's Length Property In Flex?
Nov 12, 2009I would like to put an eventListener on an ArrayCollection's length proprety, but I don't know how to go about this.
I want to do this because I only want code to execute when a certain number of things are in a certain ArrayCollection. I want Flex to wait to execute this code over the next object until that length property drops back to an acceptable level. I think I should do this with events instead of a while loop that sits there spouting NOOPs forever (which I don't know how to do either).
Flex :: ArrayCollection Not Returning Absolute Length When Filterfunction Is Applied On It
Apr 24, 2011My Dataprovider for a grid is an arrayCollection which is dynamically loaded with Objects . for example : a person object with persionID,PersonName ..etc . I applied a filter function on my dataprovider based on personID . below is my function
public function FilterFunc(item:Object):Boolean
{
var same:Boolean=String(item.personID ) == filterpersonID ;
return same;
[Code]....
this function is called whenever a new object is being added to the arraycollection . The problem now is dp.length in the above function is returning only the no of objects of the particular personID on which the filterFunction was applied instead of the absolute value . Its not limiting the size of the other objects which are runnning into thousand's causing memory issues . once i change the filterFunction to different personID , it slowly starts limiting the respective personID objects. So the sizeHandler() limits only the personID objects for which filterfunction was applied instead of the whole objects , this is the problem .
Flex :: Why Change In ArrayCollection's Length Doesn't Invoke Setter On Component Using It As Data Source
Dec 15, 2010I have a component where I expose the property 'questions' with the following code:
private var _questions:ArrayCollection;
private var questionsChanged:Boolean;
[Bindable("questionsChanged")]
[Code]....
In this component, I use commitProperties() to implement my logic.
I use Cairngorm and the 'questions' is in the model and hence it's defined as a source for data binding.
When the 'questions' ArrayCollection's size changes elsewhere in the application, it is not invoking the setter method in the component that is destination for the data binding.
Flex :: Mxml - Components Bound To Empty ArrayCollection At Load Time Don't Render As Expected When The ArrayCollection Is Updated?
Oct 27, 2009I'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:

View 2 RepliesActionscript 3 :: Flex 4 ComboBox Stays Open When Filtered
Jul 29, 2011I have a Flex 4 app with an external ItemRenderer inside of a DataGroup for a repeating form. The DataGroup dataprovider is an ArrayCollection (coll_sites). In the documentParent I have a trio of comboBoxes (Status, Year, Area) that trigger a filter function that operates directly on coll_sites.The itemRenderer has a series of textInputs and comboBoxes. Three of these comboBoxes are tied to fields in coll_sites (again, Status, Year and Area) that are filtered by the aforementioned parentDocument comboBoxes.The problem I am having is that in the itemRenderer when the field is one of the filtered ones, the itemRenderer ComboBox will not close. If it's not filtered, there is no problem. I have confirmed that the problem ComboBox updates the ArrayCollection appropriately, it just won't close unless another Item in the dropdown is selected.[code]In the ItemRenderer code above, the ComboBox for STATUS works exactly as it should but YEAR stays open after changing. In my full code, I have three such filtered fields and all three behave exactly the same. The other six fields which are not filtered, close appropriately.

Actionscript 3 :: Remove Equally Spaced Elements From An Array With Length Of 'n' To Match A Given Length 'y'?
Mar 9, 2011Let's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.
Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.

Php :: Zend_AMF: Get A ArrayCollection From Flex?
Sep 22, 2009I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection to an array in flex and then send it over. Is this true, and if so how would I do that in Flex 3? If you have a better recommendation,

Flex :: How To Get Memory Size Of ArrayCollection
Feb 2, 2010I have built an image cache which is an ArrayCollection containing images. I have built functionality so that the cache can hold a max of 250 images. However, the images can be of a different size, so it's better to limit the total memory size of all images in the ArrayCollection. How I can get the total memory size of an ArrayCollection without looping through all the items in the ArrayCollection?
