Hello, Is it possible to specifc a class property to be an ArrayCollection of a certain Interface rather than just an ArrayCollection? Thanks, Nick
[flexcoders] ArrayCollection, addAll and Refresh
I understand that ArrayCollection.addAll was added in flex sdk 3.4. I'm coding
a simple application and I'm hitting this problem. I would like to ask if
anyone knows what's happening:
Here's the source, just a simple mxml:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=creationComplete()
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
private var a:Array = [
{ key: a, value: b },
{ key: a, value: b },
{ key: a, value: x },
{ key: a, value: b }
];
private var b:Array = [
{ key: b, value: c },
{ key: b, value: x },
{ key: b, value: c },
{ key: b, value: c }
];
private var c:Array = [
{ key: d, value: x },
{ key: d, value: e },
{ key: d, value: e },
{ key: d, value: e }
];
[Bindable] public var xx:ArrayCollection = new
ArrayCollection();
public function creationComplete():void {
var i:int;
xx.filterFunction = filter;
xx.addAll(new ArrayCollection(a));
/*for (i = 0; i a.length; i++) {
xx.addItem(a[i]);
}*/
trace(Refresh is + xx.refresh());
xx.addAll(new ArrayCollection(b));
/*for (i = 0; i b.length; i++) {
xx.addItem(b[i]);
}*/
trace(Refresh is + xx.refresh());
xx.addAll(new ArrayCollection(c));
/*for (i = 0; i c.length; i++) {
xx.addItem(c[i]);
}*/
trace(Refresh is + xx.refresh());
}
private function filter(item:*):Boolean {
if (item.value == x) return false;
return true;
}
]]
/mx:Script
mx:DataGrid id=dg dataProvider={xx}/mx:DataGrid
/mx:Application
When I compile and run I get:
RangeError: Index '5' specified is out of bounds.
What I'm doing basically is to add some random array of objects into an
ArrayCollection binded to the DataGrid. And because there is a filter function
associated with the ArrayCollection, I call refresh() every time something is
added. The original use case is that this is like a drop object method for the
datagrid, so it's possible for it to be called multiple times.
I'm just curious why is this happening. Is this the desired behaviour? I'll
look into the source code later when I'm free, but this is just to get a
general feeling of the problem.

[flexcoders] ArrayCollection back to Query
I'm using Remote Objects in Flex with Cold Fusion 8 to retrieve data. Flex makes a call to a Cold Fusion CFC which runs a query and sends that back to Flex. I pick it up in Flex and attach it to an ArrayCollection which powers my grids. No problems. Now I want to go the other way. I want to send the same ArrayCollection back to a CFC and have it show up as a query. I thought if you pass an Flex ArrayCollection to ColdFusion it would be automatically interpreted as a ColdFusion query object. Either this is not the case or I am (again) doing something wrong. Has anyone tried this? Maybe share some codes examples? Thanks! Warren
RE: [flexcoders] ArrayCollection filterFunction returning item in array;
I think you want

Make sure STATUSID is a number/int and not a String, or convert it.

RE: [flexcoders] ArrayCollection filterFunction returning item in array;
No, the in operator is used to determine if an object has a particular
property. With Array, it will tell you if an index is within the bounds of
the array.
In your case, if STATUSID is an integer, it will return true for value
0,1,2,3.
I am not sure why it is returning null. Split the code up into smaller
parts and debug it.

Why not use XMLListCollection and send the xml to .net as a string? There is
little value in building an ArrayCollection of generic obects. You can
sort/filter an XMLListCollection.
XML is more verbose than some other methods, but if bandwidth is truly an
issue, then you should be looking at a binary protocol.

Hi Sam,
Basically this is the process which I am using.
.NET
Retrieve records from Oracle DB and store the same into a dataset. Return the
dataset as XML string via the command DataSet.GetXML.
Flex
In the event handler of my webservice method call, I parse the string into XML,
then ArrayCollection via the following codes:
private var _xmlData:XML;
[Bindable] private var arrDP:ArrayCollecti on = new ArrayCollection;
_xmlData = XML(event.result) ;
var oTemp:Object;
var xl:XMLList = _xmlData.children( );
var i:int;
for(i = 0; i xl.length(); i++)
{
oTemp = {NAME:xl[i]. NAME.text( ), TEAM:xl[i].TEAM. text(),
JERSEY :xl[i] .JERSEY.text( ), MANAGER:xl[i] .MANAGER. text()};
arrDP.addItem( oTemp);
}
and in my datagrid, I am setting its dataProvider to the arrDP variable.
I used Array Collection because I implemented a search and filter functionality
which searches and filters the data accordingly for the dataprovider which is
then reflected back to the datagrid.
Now, when I need to return the ArrayCollection to .NET, I simply pass the same
as a parameter to a .NET function which accepts ArrayList as parameter.
.NET
Once the function receieves the arraycollection (which is then now an array
list), I get the arrays inside the arraylist and get the values inside the
array.
I think by doing things like this, it may not be the best way.
You mentioned you'd map the XML to typed objects in .NET. How can I do this?
Instead of using arraycollection as dataprovider in my datagrid, can I use
another which would be much easier when I pass back to the .NET function?
Whats the best way to interact large set of data (datasets) between .NET and
Flex?
Thanks a lot.

Instead of using an array list and trying to emulate the type-less

does the XML from your Flex app differ too wildly to do this?
Are you using the XmlSerializer to deserialize this? Or are you using
WCF? Or are you doing it some other way, or manually?

Re: [flexcoders] ArrayCollection Does Not Show Items In Order When Passed to .NET WebService
Hi Sam Lai,
THanks for the input and my apologies for replying late since I felt the need
to get deeper on the issue I am encountering.
In my web service, the arraycollection is received as an array list and yes, it
is like an array of xml nodes.
In my arraycollection, say I have 5 columns and when one of the columns
contains an empty string, when I pass it to my .NET webservice, the arraylist
will have an array which only contains 4 columns (instead of the expected 5).
That is why the empty field is actually causing me some problems.
I am trying to find some E4x documentation / article specifically tackling this
kind of .NET and Flex integration. Do you know of some?
Thanks and regards,
Angelo

Subject: Re: [flexcoders] ArrayCollection Does Not Show Items In Order When

I just wrote up a simple C# web service that accepts an ArrayList:
[WebMethod]
public bool ArrayListTest( System.Collectio ns.ArrayList a)
{ ... }
Then in Flex I wrote this,
mx:Script
![CDATA[
import mx.collections. ArrayCollection;
private function sendWebServiceCall( ):void
{
trace(appComplete );
ws.ArrayListTest( new ArrayCollection( [ {name:bob, id:808 }, {
name:fred, id: }]));
}
]]
/mx:Script
mx:WebService wsdl=http://localhost: 63868/Service1. asmx?WSDL id=ws
mx:operation name=ArrayListTest result=trace( event.result)
fault=trace( event.fault. faultString) /
/mx:WebService
When sendWebServiceCall is triggered, it calls the C# web service and
passes the ArrayCollection to it.
In the web service, the ArrayCollection is received as an array list
of XmlNodes. Each XmlNode contains a node for each field, even if it
is an empty string.
tns:id xmlns:tns=http://tempuri. org/808/tns:id
tns:name xmlns:tns=http://tempuri. org/bob/tns:name
tns:id xmlns:tns=http://tempuri. org//tns:id
tns:name xmlns:tns=http://tempuri. org/fred/tns: name
Is this anything like what you're getting? The edge case you described
in another email about an empty string causing problems doesn't seem
to cause problems.
Also see inline.

You mentioned you'd map the XML to typed objects in .NET. How can I do
this?
As you're using a dataset, this isn't really an option. A dataset as
opposed to a collection of typed objects are two ways of handling data
from data sources; it is arguable which way is better.
The problem in your case, is that the XML generated as a result of
passing an ArrayCollection to a web service method cannot be passed
into the dataset's readXml method. (Even if it could by inferring a
schema, it would be different to your database's schema.)
The only way I know of to do seamless transfer of data without having
to parse XML is to use WebORB. Otherwise you will have to parse the
XML produced on both sides to re-create the dataset/object.
Instead of using arraycollection as dataprovider in my datagrid, can I use
another which would be much easier when I pass back to the .NET function?
I wonder if it is possible to bind your datagrid directly to the e4x
XML? That way you can pass the entire XML doc back to .NET via the web
service, and hence you can re-create the dataset using
dataset.readXML.

XML is more verbose than some other methods, but if bandwidth is truly an
issue, then you should be looking at a binary protocol.

Subject: Re: [flexcoders] ArrayCollection Does Not Show Items In Order When
Passed to .NET WebService
Hi Sam,
Basically this is the process which I am using.
.NET
Retrieve records from Oracle DB and store the same into a dataset. Return
the dataset as XML string via the command DataSet.GetXML.
Flex
In the event handler of my webservice method call, I parse the string into
XML, then ArrayCollection via the following codes:
private var _xmlData:XML;
[Bindable] private var arrDP:ArrayCollecti on = new ArrayCollection;
_xmlData = XML(event.result) ;
var oTemp:Object;
var xl:XMLList = _xmlData.children( );
var i:int;
for(i = 0; i xl.length(); i++)
{
oTemp = {NAME:xl[i]. NAME.text( ), TEAM:xl[i].TEAM. text(),
JERSEY :xl[i] .JERSEY.text( ), MANAGER:xl[i] .MANAGER. text()};
arrDP.addItem( oTemp);
}
and in my datagrid, I am setting its dataProvider to the arrDP variable.
I used Array Collection because I implemented a search and filter
functionality which searches and filters the data accordingly for the
dataprovider which is then reflected back to the datagrid.
Now, when I need to return the ArrayCollection to .NET, I simply pass the
same as a parameter to a .NET function which accepts ArrayList as parameter.
.NET
Once the function receieves the arraycollection (which is then now an array
list), I get the arrays inside the arraylist and get the values inside the
array.
I think by doing things like this, it may not be the best way.
You mentioned you'd map the XML to typed objects in .NET. How can I do
this?
Instead of using arraycollection as dataprovider in my datagrid, can I use
another which would be much easier when I pass back to the .NET function?
Whats the best way to interact large set of data (datasets) between .NET and
Flex?
Thanks a lot.

Are you using the XmlSerializer to deserialize this? Or are you using

var xl:XMLList = _xmlData.children( );
var i:int;
for(i = 0; i xl.length(); i++)
{
oTemp = {ID_TAG:xl[i] .ID.text( ), CAT_TAG:xl[i] .CAT.text( ),

fields are not in order as I have added them into the array collection.
I am expecting that in my Web Service, when I parse this arraycollection

added them, i.e. the first array in the array list would have element 0 to
be the value I placed in the ID.
Since the arraylist does
Re: [flexcoders] ArrayCollection Does Not Show Items In Order When Passed to .NET WebService
I just wrote up a simple C# web service that accepts an ArrayList:
[WebMethod]
public bool ArrayListTest(System.Collections.ArrayList a)
{ ... }
Then in Flex I wrote this,
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
private function sendWebServiceCall():void
{
trace(appComplete);
ws.ArrayListTest(new ArrayCollection([
{name:bob, id:808 }, {
name:fred, id: }]));
}
]]
/mx:Script
mx:WebService wsdl=http://localhost:63868/Service1.asmx?WSDL; id=ws
mx:operation name=ArrayListTest result=trace(event.result)
fault=trace(event.fault.faultString)/
/mx:WebService
When sendWebServiceCall is triggered, it calls the C# web service and
passes the ArrayCollection to it.
In the web service, the ArrayCollection is received as an array list
of XmlNodes. Each XmlNode contains a node for each field, even if it
is an empty string.
tns:id xmlns:tns=http://tempuri.org/;808/tns:id
tns:name xmlns:tns=http://tempuri.org/;bob/tns:name
tns:id xmlns:tns=http://tempuri.org/;/tns:id
tns:name xmlns:tns=http://tempuri.org/;fred/tns:name
Is this anything like what you're getting? The edge case you described
in another email about an empty string causing problems doesn't seem
to cause problems.
Also see inline.

I think by doing things like this, it may not be the best way.
You mentioned you'd map the XML to typed objects in .NET. How can I do
this?
As you're using a dataset, this isn't really an option. A dataset as
opposed to a collection of typed objects are two ways of handling data
from data sources; it is arguable which way is better.
The problem in your case, is that the XML generated as a result of
passing an ArrayCollection to a web service method cannot be passed
into the dataset's readXml method. (Even if it could by inferring a
schema, it would be different to your database's schema.)
The only way I know of to do seamless transfer of data without having
to parse XML is to use WebORB. Otherwise you will have to parse the
XML produced on both sides to re-create the dataset/object.
Instead of using arraycollection as dataprovider in my datagrid, can I use
another which would be much easier when I pass back to the .NET function?
I wonder if it is possible to bind your datagrid directly to the e4x
XML? That way you can pass the entire XML doc back to .NET via the web
service, and hence you can re-create the dataset using
dataset.readXML.

am referring to in a particular index.
Thanks.

[flexcoders] ArrayCollection/Min Max Problem
I have an array collection and I am trying to find the Min/Max of the values in groups. For Example my array collection has 100 values. I want to find the Min Value/Max Value between 1 to 26, 2 to 27, 3 to 28 , etc I tried to create 2 for loops in each other but for some reason during debugging/tracing it outputs wrong numbers, but if i do breakpoint then step in. I get the correct values. So the question is is there a better way than what i am doing. I am just trying to create a Stochastic formula.
Re: [flexcoders] ArrayCollection/Min Max Problem
Maybe your trace statement is in the wrong place? Seeing your code would help in solving the problem. Another way to solve these problems is to sort the data (sub)set, then just pull the first and last elements. Depending on what you want to do with the data after, this may be faster. 2009/7/1 Sherif Abdou sherif...@yahoo.com: I have an array collection and I am trying to find the Min/Max of the values in groups.

[flexcoders] ArrayCollection and Datagrid Binding and DataProvider Question
Good day.
Learning Flex here for the past two (like three actually) weeks. Using only
mxml compiler.
I have a question with regards to the above subject:
Assuming I declared an ArrayCollection as follows:
[Bindable] private var _arrItems:ArrayCollection = new
ArrayCollection([{itemNo:1, testItem:Angelo}, {itemNo:2,
testItem:Dinah}]);
This array I am binding to a datagrid as follows:
mx:DataGrid id=dgOutwardList
dataProvider={_arrItems}
useRollOver=false
height=450
width=100%
verticalScrollPolicy=auto
sortableColumns=false
draggableColumns=false
resizableColumns=false
mx:columns
mx:DataGridColumn headerText= dataField=itemNo width=20/
mx:DataGridColumn headerText=Name of Passengers dataField=testItem
width=200
mx:itemRenderer
mx:Component
mx:TextInput width=100% /
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn
/mx:columns
/mx:DataGrid
No problem initially, as the itemNo and the testItem values are displayed
properly on the datagrid.
Now for example, if I modified my first row which contains itemNo:1 and
testItem:Angelo, where I changed Angelo to Mickey, will the dataprovider
reflect the change in the said row?
How do I make so that the changes in the datagrid be reflected into the
ArrayCollection? such that when I changed the testItem data for the first row
and access the item, via:
_arrItems.getItemAt(arrLength -1).itemNo
_arrItems.getItemAt(arrLength -1).testItem
The result would be 1 and Mickey respectively?
I am a bit puzzled on how databinding actually works in Flex. Is it like a
two-way live update (such that when you modify the value in the datagrid, it is
reflected back to the arraycollection)?
Would love to hear your inputs.
Thanks and regards,
Angelo
[flexcoders] ArrayCollection to Delimited String

[flexcoders] arraycollection vs listcollectionview
I'm confused. I have an ArrayCollection. And I listen for the COLLECTION_CHANGE.Remove event to know when to delete the item from the database. For displaying the contents of my ArrayCollection, i am using a ListCollectionView with a filter function applied to it, so that the filter function does not affect all views using the same ArrayCollection. But, when I change the value of a property on an item in the ArrayCollection that causes the filter to now filter OUT the item, the ListCollectionView dispatches a COLLECTION_CHANGE.Remove event. This causes my code to remove the item from the db, undesirably. Now I understand that the ListCollectionView must dispatch these events to update the ListBase, but why isn't the target different so that I can tell whether the Remove event came from the ArrayCollection itself or just a ListCollectionView of it?
RE: [flexcoders] arraycollection vs listcollectionview
That's a nasty little bug. I haven't encountered that myself yet but I can see where that would happen.

[flexcoders] ArrayCollection vs XMLListCollection
How come when I'm setting up a data grid using an ArrayCollection as
the datasource I dont have to specify the contents of the data grid
columns? I can just do this:
mx:DataGrid id=dg1 x=42 y=0 width=950 height=100
dataProvider={bookData.lastResult.books.stock} /
But in order to get anything to appear on the data grid with either XML
or XMLListCollection I have to do the column layout (like this)?
mx:DataGrid id=dg3 x=42 y=300 width=950 height=100
dataProvider={bookStock2}
mx:columns
mx:DataGridColumn dataField=name headerText=name/
mx:DataGridColumn dataField=author headerText=author/
mx:DataGridColumn dataField=categoryheaderText=category/
mx:DataGridColumn dataField=description headerText=description/
/mx:columns
/mx:DataGrid
Thanks in advance,

Re: [flexcoders] ArrayCollection vs XMLListCollection
Some code magic in the background.
I bet if you drill down into the component code for DataGrid and/or
DataGridColumn you'll find comments that explain this.
If I had to guess, it is relatively [knock on wood] easy to parse an
object and find the properties on it. I think a for loop will do it.
But, XML is much open in terms of where do I find data than an
ArrayCollection of objects would be.

If you don't specify columns, the DataGrid uses ObjectUtil.getClassInfo to get
the list of properties. For XML, getClassInfo returns the attributes and not

RE: [flexcoders] ArrayCollection DataProvider question.
That is not as bad as I thought it might be(I was expecting to see the
default resultFormat. E4x is good!), but it is a bit odd. You are
manually building an ArrayCollection of XML nodes.
I don't see any reason to do that. Just use XMLListCollection, and
avoid the loop.
Now, best practice, or at least this list's apparent consensus of best
practice, is to do what you are doing, but instead of adding xml nodes,
you populate a strongly data typed Value Object and add tht to the
ArrayCollection. This is probably the most efficient and performant
approach.
But I mostly use XML and XMLListCollection.

[flexcoders] ArrayCollection COLLECTION_CHANGE event doesn't fire right away?
Hi all,
I'm trying to detect changes in an ArrayCollection which is bound to a
DataGrid with some editable components. For some reason, however, the
event only seems to fire when the focus is change. For example, I
check a check-box, and nothing happens. When I then click somewhere
outside of the checkbox, the event is fired. Furthermore, If I check
the box twice before changing focus, nothing at all happens.
Is is possible that the event is only fired when the DataCollection is
refreshed, and that the refresh is not occurring until the focus changes?
Here is an example of what I'm doing (colors is the id for the
DataGrid associated with the colors ArrayC:
import mx.collections.ArrayCollection;
import mx.events.CollectionEvent;
import mx.controls.Alert;
[Bindable]
private var colors:ArrayCollection = new ArrayCollection([
{color:Red, display: true},
{color:Blue, display: true},
{color:Green, display: true}
]);

RE: [flexcoders] ArrayCollection COLLECTION_CHANGE event doesn't fire right away?
DG editing is session and row-based by default. Data isn't written back to the
data object until you change cells, and notifications are blocked until you
change rows.
For click-based cells like checkbox, I usually add a change handler that sets
the field right away.

Subject: [flexcoders] ArrayCollection COLLECTION_CHANGE event doesn't fire
right away?
Hi all,
I'm trying to detect changes in an ArrayCollection which is bound to a
DataGrid with some editable components. For some reason, however, the
event only seems to fire when the focus is change. For example, I
check a check-box, and nothing happens. When I then click somewhere
outside of the checkbox, the event is fired. Furthermore, If I check
the box twice before changing focus, nothing at all happens.
Is is possible that the event is only fired when the DataCollection is
refreshed, and that the refresh is not occurring until the focus changes?
Here is an example of what I'm doing (colors is the id for the
DataGrid associated with the colors ArrayC:
import mx.collections.ArrayCollection;
import mx.events.CollectionEvent;
import mx.controls.Alert;
[Bindable]
private var colors:ArrayCollection = new ArrayCollection([
{color:Red, display: true},
{color:Blue, display: true},
{color:Green, display: true}
]);
// Watch for changes to DataGrid CheckBox's
private function init():void {
colors.addEventListener(
CollectionEvent.COLLECTION_CHANGE, onChange
);
}
public function onChange(evt:Event):void {
Alert.show(Datagrid altered!);
}
Any ideas? Any advice would be greatly appreciated.
Thanks!

[flexcoders] arraycollection merge
Hi I have three different arraycollections and I want to bind them all as dataprovider to a datagrid. How do I do that? Can a datagrid have have 3 dataprovider and can it display all these dataproviders' info at the same time? Or I do need to merge my three arraycollections into one and then bind them to the grid? If I do need to merge the arraycollections together than what is the easiest way to do so? Regards

Because they are asynchronous, there can be multiple pending RPC data calls. There is no assurance that the first RPC call is the first returned. I guess I just have not developed large enough applications to see what you are stating here. I normally create a HTTPService object then call 1-2 asynchronous calls depending on user interaction with the app. Between the time the result returns, lastResult is set, the result event is dispatched, calling your handler, and your handler gets to the line that uses lastResult, it is very possible that another result has returned, overwriting the value in lastResult. Typically it is actually set to null by the framework, rather than sneaking in some other data, but that is just as dangerous. This was a real issue in a thread six or eight months ago. This all really depends on how you develop the application. I am not saying you are wrong or stating something incorrectly, just that this example is not relevant to most people creating small/medium apps. Most people are doing good to even have a single HTTPService object within their code. If you only call a single RPC at a time, there will be no problem, but complex apps often have many outstanding calls an a given moment. Ah, I see. I appreciate the insight. Why take any risk? Is there some reason you **like** lastResult over using the event.result object? I am not taking a side on anything really. I am just stating that in my little experience, as well as documentation and other resources read, that the lastResult-method is used by the vast majority. I personally appreciate you explaining the lastResult vs. event.result methods. Tracy Thanks Tracy. Mike Duncan ISSO, Application Security Specialist Government Contractor with STG, Inc.

[flexcoders] ArrayCollection
All, I am using an ArrayCollection that I populate with the results from a ColdFusion RPC. All works well when there is more than 1 record. When only 1 record is returned, the data is not assigned to the ArrayCollection. Any suggestions? Thank you, jh
RE: [flexcoders] ArrayCollection
A well known issue. The FP is unable to differentiate between an Object and an Array with a single element. I use XML until I have full control, so I don't see this issue. You can examine the result object to see what it really contains and respond conditionally, or you can use toArray(), which is in one of the Utils packages.

RE: [flexcoders] ArrayCollection
Mike,
It is dangerous to use lastResult in this manner:
scans = new ArrayCollection([getScan.lastResult.vector.scan]);
You are not garrunteed that it will have the value in the result you
expect.
In most cases it will work ok but the correct way is:
scans = new ArrayCollection([event.result.vector.scan]);
lastResult is intended only for use in binding expressions.

using the event.result object?

I am not quite sure by what you mean ...are not garrunteed that it will
have the value in the result you expect. There is only one result. And,
by dangerous, are you talking about a memory leak or something?
If there is a case when I get no results, then I can understand this
logic, but in my case, there is always at least one result. A single
child within the root element of the returned XML that is.
I appreciate the heads up though.

Ok, had not noticed the http bit, as the initial post mentioned RPC and in
my mind/head RPC == RemoteObject..
and i do not have any similar problems with remote object calls :-)

[flexcoders] ArrayCollection bound to an Array.
Is it possible to bind an ArrayCOllection to an array, like so
public var summDataForControllers:Array = new Array;
public var _summDataForContrAC:ArrayCollection = new
ArrayCollection({summDataForControllers});
I have a modelLocator that contains these to items (above) and I want
a component to bind to the arrayCollection. I am storing the
information in the array first because when I try to update the
arraycollection from my component and then access a certain item in
the arraycollection I get Index 0 out of bounds. So in other words I
iterate and say arrayCollection.addItemAt(i) then try
arrayCOllection.getItemAt(i) I get the out of bounds issue.
But if I iterate and store the information in an array everything is
fine, but now my component can't listen for updates, which is the
reason I am trying to bind my arraycollection to the array.
Thanks in advance for any help.
RE: [flexcoders] ArrayCollection bound to an Array.
Your approach to the problem doesn't appear to be correct. Some
additional code would be helpful.

Re: [flexcoders] ArrayCollection bound to an Array.
You could bind a setter, something like this (written in gmail, this was not
compiled):
private var array:Array;
private var arrayCollection:ArrayCollection;
public function ClassName(..args) { //Constructor
array = new Array();
BindingUtils.bindSetter(setArrayCollection, this, array);
}
private function setArrayCollection(array:Array):void {
arrayCollection = new ArrayCollection(array);
}
This will cause the setter function to run everytime array changes. But do
some reading on when Array does and does not dispatch a change event...

[flexcoders] ArrayCollection ChangeEvent does noget get dispatched when filterFunction is set
It appears that an arraycollection's changeEvent (CollectionEvent.COLLECTION_CHANGE) does not get called correctly when FilterFunction is set. Is anyone else experiencing this behavior, and if yes: is it a feature or a bug ?

Re: [flexcoders] ArrayCollection filterFunction only gets called on root item
The filterFunction only applies to the ArrayCollection. By hierarchy, I
assume you mean you have an ArrayCollection that contains ArrayCollections.
In other words, objects in your original ArrayCollection have, say, a
children ArrayCollection. In order to do what you're describing, you would
have to set the filterFunction on each of these child's filterFunction and
each of there's, etc.
In the past, I have done something like this to achieve what you're talking
about:
public function filterMenuItems(filter:IMenuFilter):void {
if (children) {
// need to clear all filters first, otherwise hidden higher
levels won't come back
children.filterFunction = null;
children.refresh();
for (var i:int=0; i children.length; i++) {
if (children.getItemAt(i) is Menu) {
Menu(children.getItemAt(i)).filterMenuItems(filter);
}
}
children.filterFunction = filter.menuItemFilter;
children.refresh();
}
}
Here, a Menu is filtered by calling it's filterMenuItems method with a
filter object, traversing down through other Menu's children (via the
recursive call) setting the filterFunction.

[flexcoders] arrayCollection event COLLECTION_CHANGE issues?
First thanks for all your help guys. I'm making nice strides learning
this language quickly.
I'm working with events now. I created an arrayCollection to capture a
query from coldfusion. I have the data being dumped into this variable
just fine (I can do a combobox on it and see all of it). Now what I
want to do is set some variables based on these items. I created an
event to watch the arrayCollection which would run a function to reset
the variables automatically. Here's what I did:
This is all within a singleton class...
Created the [Bindable]acUser array collection
[Bindable] public var acUser:ArrayCollection = new ArrayCollection();
Created an init() function to set up the event handler:
private function init():void
{
acUser.addEventListener(CollectionEvent.COLLECTION_CHANGE,
acUser_collectionChange);
}
Created a function to set the variables if the event hit:
private function
acUser_collectionChange(event:CollectionEvent):void
{
strEMail =
ObjectUtil.toString(acUser.getItemAt(0).strEMail); (not sure if this
call is correct -yet-)
trace(strEMail);
}
Modified the header for the page to run the init() function
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=init()
xmlns=*
xmlns:controllers=com.cfgenerated.controllers.*
xmlns:login=com.cfgenerated.views.login.*
layout=absolute
currentState=NotLoggedIn
This should be all I need to do, right?
When I push the data into the singleton:
GlobalVars.instance.acUser = event.result as ArrayCollection;
The event does not fire. Any ideas?
TIA!
Re: [flexcoders] arrayCollection event COLLECTION_CHANGE issues?
You're initializing the acUser collection when the singleton is created and
adding a listener, which is fine. However, when you're getting the results
back, you're changing the acUser collection reference to a different
ArrayCollection
GlobalVars.instance.acUser = event.result as ArrayCollection;
So your singleton still has a listener registered on the original
ArrayCollection, but your singleton model now contains a reference to the
new ArrayCollection returned from the service. To keep your references
pointing to the same ArrayCollection and still get the COLLECTION_CHANGE,
you could play games like this:
GlobalVars.instance.acUser.source = ArrayCollection(event.result).source;
GlobalVars.instance.acUser.refresh();
In that you're swapping out the underlying Array the collection is wrapped
around, and then calling refresh will dispatch teh COLLECTION_CHANGE, firing
any bindings and calling your listener code.

[flexcoders] ArrayCollection (AS) and ArrayList (java) not in sync)
Hi.
Im having a problem retrieving a list of objects from the server.
Im using blazeds and have successfully retrieved lists of objects using the
following construct:
Im dealing with a list that has Site Objects
mx:RemoteObject id=srv destination=theService/
mx:DataGrid id=sites dataProvider={srv.getSites.lastResult}/
On the server the ArrayList is being generated correctly with 2 different Site
objects. On the client side Im getting the last of the 2 sites twice.
So I iterate through the ArrayCollection and there are 2 same Objects in there.
Odd...
Any suggestions would be welcome.
Kind regards.
Luke.

Hi.
Im having a problem retrieving a list of objects from the server.
Im using blazeds and have successfully retrieved lists of objects using the
following construct:
Im dealing with a list that has Site Objects
mx:RemoteObject id=srv destination=theService/
mx:DataGrid id=sites dataProvider={srv.getSites.lastResult}/
On the server the ArrayList is being generated correctly with 2 different
Site
objects. On the client side Im getting the last of the 2 sites twice.
So I iterate through the ArrayCollection and there are 2 same Objects in
there.
Odd...
Any suggestions would be welcome.
Kind regards.
Luke.

Re: [flexcoders] arraycollection and tree
Hi Luke,
Just create a List in Java and return it. alternatively you can add it
to a Value Object and then return it. below is example of my function,
CategoriesVo is simple java class with three public variables.
public List getCategoriesAll(){
List list = new ArrayList();
String query = SELECT main.id, main.name, sub.name FROM
maincategories AS main, subcategories AS sub WHERE main.id =
sub.maincategoryId;
//String query = SELECT * FROM maincategories;
try {
ResultSet results =
connManager.stmt.executeQuery(query);
//results.first();
String secondKey = ;
String firstKey = ;
Integer categoryId;
while (results.next()){
CategoriesVo categories = new CategoriesVo();
firstKey = results.getString(2);
categoryId = results.getInt(1);
secondKey = results.getString(3);
categories.mainCategory = secondKey;
categories.subCategories = firstKey;
categories.categoryId = prevCategory;
list.add(categories);
// hashMap.put(secondKey, list);
// System.out.println(adding to the hashmap
+ secondKey);
}
} catch (SQLException e){
}
return list;
}
this can be cast to arraycollection in Flex or you can loop through
the result and add it to a collection.
hope this helps.

[flexcoders] ArrayCollection of String as single-column DataGrid provider
Hi!
I have ArrayCollection filled with String:
mx:ArrayCollection id=dp
mx:StringString 1/mx:String
mx:StringString 2/mx:String
/mx:ArrayCollection
DataGrid's dataProvider is array collection above and DataGrid has
only one column.
What I want is to have ComboBox as inplace ItemRenderer/Editor, but I
don't know what to set in DataGridColumn's dataField property since
ArrayCollection contains String and not Object.
Something like this:
mx:DataGrid dataProvider={dp} editable=true
mx:columns
mx:DataGridColumn headerText=My Strings dataField=??
editorDataField=labelText rendererIsEditor=true
mx:itemRenderer
mx:Component
mx:ComboBox
dataProvider={outerDocument.comboProvider}
labelField=name /
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn
/mx:columns
/mx:LgnDataGrid
Any ideas how to do this?
Thanks,

[flexcoders] ArrayCollection refresh event listener

[flexcoders] ArrayCollection Question
I am dragging/dropping rows from one grid to another. At the drop I will be calling a .cfc to get more information for the second datagrid. I have several questions about the data that I'm adding. 1. To add the data manually after I've captured my drop event do I need to use the Icollection? class to put the data into the datagrid? 2. If in-fact I'm using the Icollection class, when I add the data is that change being made in the arrayCollection? The reason that I ask is that once changes are made to the data, either by the automatic insert, or if a user edits a cell, can I then loop over the arrayCollection to insert the changes back into the database? If anyone has any links about doing this I'd be grateful. Also, my second datagrid is both drop and drag enabled. I want users to be able to re-order the items in the datagrid as well as add/edit items. This is a scheduling application. I'll then save those changes to the db. I noticed that when I went to re-order items in the second datagrid I actually made a copy in the new location. The old row remained. Is there a special way to make sure that once I've made the move the old row is removed? I really appreciate the pointing in the right direction. Flex 2 is really slick. I'm just running into some newb wall. Again, thanks. Mark F.
RE: [flexcoders] ArrayCollection Question
You can use ICollectionView, but you'll probably find the IList methods easier (addItem). Those methods will change the array that is the source of the AC. Re-ordering should require that dragMoveEnabled=true.

[flexcoders] ArrayCollection XMLList?
I have an ArrayCollection in Flex which contains the delivery information for a given stock item: boxes quantity 10 20 15 20 17 20 etc how can I convert this into an XMLList so that it can be a dataProvider for a tree control where each line is a branch of the tree please?
Re: [flexcoders] ArrayCollection XMLList?
Assuming your ArrayCollection contains strongly typed objects, I think you can make the ArrayCollection itself be the dataprovider for your tree. Your class (the data stored in the ArrayCollection) just needs to implement the get children():Array and get label():String method iirc. hth Scott candysmate wrote: I have an ArrayCollection in Flex which contains the delivery information for a given stock item: boxes quantity 10 20 15 20 17 20 etc how can I convert this into an XMLList so that it can be a dataProvider for a tree control where each line is a branch of the tree please?
RE: [flexcoders] ArrayCollection XMLList?
Whether the objects are strongly-typed or not, you can stick the AC in as the Tree's DP, but you'll need a custom ITreeDataDescriptor to tell the tree what is a branch and what the children are.

[flexcoders] arraycollection contains() method
Hi there,
I want to compare two arraycollection and take the different items

False. So, here's my code. Please show me where I did it wrong.

to, data:colAssignedto}, {name:Start date, data:colStartdate},

RE: [flexcoders] arraycollection contains() method
Each time you use {} you create a different object, so the two
collections have different objects with the same data. Contains just
sees if the reference to an object is in the collection and doesn't
investigate internal properties.

[flexcoders] ArrayCollection not working? Pulling out my HAIR!!!

[flexcoders] ArrayCollection to xml file function
I am trying to get some things working with my app and apollo preview.
I can get it to save a file locally when it goes offline fine. But I would like
to start extending it so that I can give it an arrayCollection(s) and it will
write out an xml structured file.
This is what I am using to save a basic string.
private function saveFile():void{
var file:File =
File.appStorageDirectory.resolve(Files/userinfo.txt);
var stream:FileStream = new FileStream()
stream.open(file, FileMode.WRITE);
var str:String = loggedinuser.toString() + \r + other data;
str = str.replace(/\r/g, File.lineEnding);
stream.writeUTFBytes(str);
stream.close();
str = ;
}
any snippets or links to show me how to export arrays/arrayCollections would be
appreciated :)

Re: [flexcoders] ArrayCollection problem (binding to a Datagrid)
this has been addressed in a previous post.
do a type check for objectproxy before assigning here:
grilleTerrainsACDP = event.result.terrains.terrain;
to have this:
if(event.result.terrains.terrain is ObjectProxy){
var t:Array=
ArrayUtil.toArray(event.result.terrains.terrain);
grilleTerrainsACDP= new ArrayCollection(t);
}else{
grilleTerrainsACDP = event.result.terrains.terrain;
}

Any idea?
I use a ArrayCollection for ICursorView...

RE: [flexcoders] ArrayCollection problem (binding to a Datagrid)
When data is sent over the wire from a server, we have to guess whether
it is a single data object or an array of objects. If we see an xml tag
twice we know it has to be an array, but if there is only one tag, we
assume it is an object.
You can simply test to see if the result is an ObjectProxy or an
Array/ArrayCollection and convert it to an array if needed.

If I have my dataprovider in the following manner:
var dataProvider = [{Date: 02-12-2007, Company1: 20, Company2: 30},
{Date: 02-09-2007, Company1: 20, Company2: 30},
{Date: 02-08-2007, Company1: 20, Company2: 30}]
How can I determine programatically:
1. The number of companies.
I dont't seem to be able to figure out how to find the number of
items in a particular element of the ArrayCollection.
2. Is there a way to structure the dataProvider so that I can also
include the company names. Thus, I can use those names for my legend.
Thanks.

[flexcoders] ArrayCollection to comma-delimited list?
Couldn't quite figure this one out. I have a multi-level arraycollection and I need to write it out in flex as two separated lists - i.e. itemA[0]: 1, 2, 3, 4 itemB[1]: 5, 6 itemC[2]: 7, 8 I'm currently using two repeaters with mx:Text to properly view the data, but of course, that just ends up as a bunch of separate text boxes vertically. Since mx:Text doesn't have an itemRenderer, I'm not quite sure how to do this.
[flexcoders] ArrayCollection contains not working
Hi,
I've been trying to filter an ArrayCollection with the objects that not
exist in another ArrayCollection. I use the contains method, but it seems
that does not work.
In the following thread seems that others are having the same problem with
XMLListCollectionView:
http://www.mail-archive.com/flexcoders@yahoogroups.com/msg55025.html
Someone knows if contains method really works? maybe we are using in a wrong
way?
Here is my filter:
private function myFilter(item:Object):Boolean {
if(model.myac.contains(item))
return false;
else
return true;
}
And I use the following implementation of ICollectionView
mx:ListCollectionView
id=mylcv
list={model.myac2}
filterFunction=myFilter/
Something wrong here?
Thanks.

[flexcoders] ArrayCollection Splice?
I'm porting over one of Ely's component's data provider from accepting an Array to accept an ArrayCollection. He uses item.splice a lot where item is typed as an array. I want the same functionality in an array collection. Item[0].splice works, but im not sure this is the right way to do it. Should i use item.list.addItemAt? Thanks! -Nate
