Re: [flexcoders] Add FDS returned AS3.0 native array to local SQLlite DB?

2) Most importantly, Does anyone have a favorite method to write from an
Array that is received from FDS to a local SQLlite database?
When I try to loop through like this which I have modified from an
example:

conn.open(dbFile);
conn.begin();

insertRow.parameters[ 2] = users[i].lName;
insertRow.parameters[ 4] = users[i].phone;
insertRow.execute();
}
conn.commit();
END CODE--
I get an error saying that SQLStatement.text property can't be changed as
below:
Error: Error #3106: Property cannot be changed while
SQLStatement.executing is true.
at Error$/throwError()
at flash.data::SQLStatement/set text()
at

I'm trying to create an offline copy of our online database for quicker

and...
3) Before I start looking at code samples Is there any way to develop
using LiveCycles on a Mac?
Thanks in advance... again!

[flexcoders] How do I print multiple objects with no page breaks??
I'd like my application to print multiple objects without forced page breaks between them. If I use the PrintJob.addObject() method, there are forced page breaks. I have several textarea.htmltext objects, several graphs, and several legends that I would like to string together to form a document for printing. I want to have this come out paginated the way I want, not one object per page. Is there any way to do this in Flex 2 or 3 beta? Is there an example out there I can look at? Help would be much apprecaited - Thanks Tony

[flexcoders] Two way binding
I am trying to figure out what both ways of data binding are.
Basically we have two subjects for data binding: DataGrid and a Form.
With DataGrid it is pretty clear: dataProvider. But with form? It
does not have such a dataProvider property (Which is in my opinion it
should have). So, what's a solution for that? DataModel? Which it
turn does not have dataProvider either. But it does have a source.
Source of what? Data? Ok, let's stick to dataModel. But then I am
reading that it's better to use class-based models. Here is an
example of class-based model form Help:
package
{
[Bindable]
public class ShoppingCart {
public var items:Array = [];
public var total:Number = 0;
public var shippingCost:Number = 0;
public function ShoppingCart() {
}
public function addItem(item:Object, qty:int = 1,
index:int = 0):void {
items.splice(index, 0, { id: item.id,
name: item.name,
description: item.description,
image: item.image,
price: item.price,
qty: qty });
total += parseFloat(item.price) * qty;
}
public function removeItemAt(index:Number):void {
total -= parseFloat(items[index].price) * items[index].qty;
items.splice(index, 1);
if (getItemCount() == 0)
shippingCost = 0;
}
public function getItemCount():int {
return items.length;
}
public function getTotal():Number {
return total;
}
}
}
Two questions:
1. How the data is getting into a picture here?
2. How am I using this model in my mxml file?
Sorry if I am asking something obvious, but I am just having problem
understanding why data-centric environment does not have a straight
way of binding data both ways. All I would want is to assign a data
source to my form and then specify data fields for each control in
the form. Simple as this. Is this possible in Flex?
Thanks
Re: [flexcoders] Two way binding
What's wrong with this?

Now, you can use the Binding tag to bind the value in the above back to the
source, your datagrid in this case, but its not really a good idea, though
YMMV.

RE: [flexcoders] Newbie XML to ArrayCollection Confusion
You can't convert directly, unless you use
resultFormat=object(default), which converts your sml into a nested
dynamic object structure. But you have no control over this conversion,
and it can have some side-effects, particularly with data type
conversions.
People often convert xml into an ArrayCollection of strongly typed
objects, because accessing strongly typed pbjects is significantly
faster than accessing XML, which this can help performance with very
large data displays (hundreds of renderers). You will need to loop over
the XMLList (xmlData.score), and build the value object items and add
them to the ArrayCollection manually.
But, why not simply use XMLListCollection?
hScores = new XMLListCollection(xmlData.score);

Subject: [flexcoders] Newbie XML to ArrayCollection Confusion
I'm hoping someone can help explain how to retrieve an XML doc via
webservice and then create an ArrayCollection from it. Using the code
and xml below, I am able to retrieve the xml alright and access the
nodes, but when I attempt to convert the xml object to an array I end
up with a single element array.
My xml document looks like:
?xml version=1.0 encoding=UTF-8 ?
- scores
score position=14/score
score position=21/score
score position=32/score
score position=43/score
score position=55/score
score position=60/score
score position=79/score
score position=86/score
score position=98/score
score position=107/score
/scores
My webservice event handler looks like:
public function hScoresHandler(event:ResultEvent):void {
var xmlResult:XML ;
var hScores = new ArrayCollection();
xmlResult = new XML(event.result);
// This properly outputs the entire XML document
trace(xmlResult);
// These properly output the content from different nodes in the
// XMLM document
trace(first (0) position: + xmlResult.score[0]);
trace(five position: + xmlResult.score[5]);
trace(five position: + [EMAIL PROTECTED]);
// Convert XML to Array
hScores = ArrayUtil.toArray(xmlResult);
// For some reason this outputs a null string
trace(hScores);
// Why is the length only one?
trace(length: + hScores.length);
}

RE: [flexcoders] Two way binding
By dataModel, are you referring to the ShoppingCart class you posted?
You have to put the data into it. Get the data from the server, however
you wish, and in the result handler, assign the data to an instance of
the data model class, using the methods or properties it provides. Then
bind the form elements to propeties in the model.

RE: [flexcoders] Two way binding
Simplicity. Less code. Maintainability. Standardization, well known
API.
Note that in the scenario I describe, the simplicity produces a
dependency between the client data model and the data transport. If
someone changes the XML you are consuming, you will have to change the
code. For some this is unacceptable and they require level of
abstraction between the transport and the model. It is just up to your
particular requirements.

[flexcoders] Re: Newbie XML to ArrayCollection Confusion
Thanks for the suggestion Tracy, I will look into that!

You can't convert directly, unless you use
resultFormat=object(default), which converts your sml into a nested

conversions.
People often convert xml into an ArrayCollection of strongly typed
objects, because accessing strongly typed pbjects is significantly
faster than accessing XML, which this can help performance with very
large data displays (hundreds of renderers). You will need to loop over
the XMLList (xmlData.score), and build the value object items and add
them to the ArrayCollection manually.
But, why not simply use XMLListCollection?
hScores = new XMLListCollection(xmlData.score);

Subject: [flexcoders] Newbie XML to ArrayCollection Confusion
I'm hoping someone can help explain how to retrieve an XML doc via
webservice and then create an ArrayCollection from it. Using the code
and xml below, I am able to retrieve the xml alright and access the
nodes, but when I attempt to convert the xml object to an array I end
up with a single element array.
My xml document looks like:
?xml version=1.0 encoding=UTF-8 ?
- scores
score position=14/score
score position=21/score
score position=32/score
score position=43/score
score position=55/score
score position=60/score
score position=79/score
score position=86/score
score position=98/score
score position=107/score
/scores
My webservice event handler looks like:
public function hScoresHandler(event:ResultEvent):void {
var xmlResult:XML ;
var hScores = new ArrayCollection();
xmlResult = new XML(event.result);
// This properly outputs the entire XML document
trace(xmlResult);
// These properly output the content from different nodes in the
// XMLM document
trace(first (0) position: + xmlResult.score[0]);
trace(five position: + xmlResult.score[5]);
trace(five position: + [EMAIL PROTECTED]);
// Convert XML to Array
hScores = ArrayUtil.toArray(xmlResult);
// For some reason this outputs a null string
trace(hScores);
// Why is the length only one?
trace(length: + hScores.length);
}

[flexcoders] Design view oddities?
Hi All, I'm using Flex 3 Beta 3 and still having some oddities with design view where my components don't layout correctly.

It actually looks like these may be my custom components from Flex 2 anyone have a similar experience? A fix? -Ken
[flexcoders] interface inheretence
Hello, I just wanted to make sure my logic was correct so I don't waste a bunch of time typing up all this code to find out it doesn't work. With the given class structure: # UserModel implements IUserModel # ChildUserModel1 extends UserModel implements IUserModel, IChildUserModel # ChildUserModel2 extends UserModel implements IUserModel, IChildUserModel # ChildUserModel3 extends UserModel implements IUserModel, IChildUserModel etc. If I have a class instance where the exact implementation could be any of the above classes, and is determined at run time, would it be safe/correct to define a variable of type IUserModel and then strong type it as either IUserModel or IChildUserModel depending on its expected implementation? For instance: # var user:IUserModel; # user = new UserModel(); # trace( IUserModel(user).someUserProperty ); # user = new ChildUserModel2(); # trace( IChildUserModel(user).someChildUserProperty ); (assuming the properties are defined in the interface of course) Is there a safer/more correct way to accomplish this given that the property always starts off as a UserModel and may or may not become any one of the ChildUserModel classes who share a common interface? note: Any of this can be changed, I just need to be able to have a class that acts as an IChildUserModel when it is one, or as a UserModel when it's not. There is only one kind of UserModel, so I'm not sure if the IUserModel interface is even necessary. I just wasn't sure how to define the variable so it could be either one. Any input or advice will be greatly appreciated. Thanks for your time! ...aaron
[flexcoders] Re: What event to catch
You certainly could put the listener there but that would cause a number of disadvantages. It would make for a less clear separation of duties because your renderer class would then contain logic as well. In the context of a large application you definitely would not want to be setting data and performing similar actions in a multitude of different places like that either as it would make maintenance and troubleshooting a nightmare. It would also make your renderer far less generic/reusable. In a real application the listener wouldn't be at the Application root but in an appropriately high-level view, such as a screen/page/form.

Hi Everyone, First of all, Happy New Year Second, I have managed to resolve the problem. It had nothing to do with the ArrayCollection returned from the webservice.

RE: [flexcoders] Icon for Button
DGColumn extends CSSStyleDecl and is assigned as the styleName property
of each renderer. When you call setStyle, you are adding new styles
that each renderer will pick up, just as if it were a normal CSS
selector.
I would expect icon, MyIconClass to work.

Alex,
This looks like a very useful piece of information, of which I was not
previously aware. It's not quite clear to me what you mean, however.
Could you expand on it a little, or else point me to some documentation
that does?
When you say the column is the styleName, what exactly do you mean? Is
that the column header text, or perhaps the dataField property of the
DataGridColumn?
Also, since the DataGridColumn class extends CSSStyleDeclaration, what
would be the effect of calling setStyle(icon, MyIconClass) on the
DataGridColumn object itself?
