[flexcoders] Re: Binding behaviour
I have to disagree. If a child property is a class or a collection, you will
be setting a reference to the same objects in the cloned parent. Thus, updates
to the child property will be made to both the clone and the original.
ObjectUtil.copy() is another good way to clone, but does not always work for
deeply nested objects.

Ok. But Its Not compulsory that you have to write a clone method. Anyways
other way you can try is
public function cloneLeaf():CallMonitoringLeaf
{
var obj:CallMonitoringLeaf = new CallMonitoringLeaf();
obj.optionCallMonitoring = this.optionCallMonitoring;
obj.nodesSelected =this.nodesSelected;
obj.dataCallMonitoring = this.dataCallMonitoring;
obj.nodeName = this.nodeName;
return obj;
}
So now calling cloneLeaf() returns new duplicated object.
Hope this works for you. I did't test it, however your reply will tell
about that. :)

[flexcoders] Re: right align the gridcolumn text
ClassFactory doesn't support setting styles; they're different than properties.
You can get around this by either:
1) use a custom item renderer that has a styleName or css selector.
2) extend ClassFactory to support setting styles on the item renderer
instances. See com.blogagic.core.UIComponentFactory at

[flexcoders] Re: Flex 4: MouseOver not firing on a UIComponent Item Renderer
It doesn't seem that skinning is something that Adobe considered would need to be done in a skin class, for an item renderer. But, you can apply a skin class to them if desired. At each level: GroupBase, Group, DataRenderer, and finally ItemRenderer, you get additional functionality; and consequently, a little more overhead. For instance, if you used ItemRenderer instead of UIComponent, you could use the hovered state to control the visibility of the button. However, I think that you're going about it the most efficient way in creating AS item renderers instead of mxml; especially for ADG. -TH --- In flexcoders@yahoogroups.com, Nick Middleweek nick@... wrote: Thanks for the tip...

[flexcoders] Re: Why don't horizontalCenter and verticalCenter work with Spark ColumnConstraints?
Ok, that makes a little more sense now. It can still work, but instead of
moving the boxes, during transition, move the groups; and resize the boxes
within the groups. As an alternative, you could choose to use a custom layout
class.

Can't do it. Boxes must be constrained via ConstraintColumns. The boxes
switch sides, resize, appear and disappear, etc. via different states and
there are transitions on those states to ease the boxes in as they move and
resize. Picture a reverse button upper right that when clicked reverses
the position of the boxes. When the boxes reverse, they smoothly transition
to their new reversed positions. Those transitions won't work if the
components are in different groups. They have to be horizontally centered on
a ColumnConstraint, not a Group container.
This isn't a new app. It's an existing app with a well designed UI. I'm
just transitioning to Spark so as to take advantage of the new skinning
model and facilitate parallel browser and mobile skins. Can't change the
app's behavior in the process.
In any event, I heard back from Adobe on this. They said, we didn't have
enough time to implement horizontal/verticalCenter in the last release
(hopefully coming in the next!).. I asked if they meant for all Spark
containers or what. They responded, Yes, basically, they are not
implemented in ConstraintLayout. ConstraintLayout handles all of the
ConstraintColumns/ConstraintRows layout logic. So that leaves me stuck
until the next release unless I can find a workaround.

[flexcoders] Re: Best Practice for Subclassed UIComponent and DataProvider
You have the right idea; to encapsulate the dataProvider, validation and change
event handler. But, instead of putting them inside the control, wrap all of
that into a common facilities model, that gets used anywhere it's needed in the
application. I stopped using Cairngorm a long time ago, but hopefully the
newest version supports dependency injection; so you can just inject a
reference to the facilities model where needed, and hook it up to the combo
box. That would be best practice. But, at the end of the day, the goal is to
make it work, so...

[flexcoders] Re: How to call container's method into component file
That's bad advice Rishi; that leads to tight coupling and parent abuse. It's
ok to have a parent call a method on a child ( data binding is preferred
though). But, children shouldn't call methods directly on their parents.
Instead, have the child component dispatch an event to initiate the save method
on the parent.

[flexcoders] Re: Best Practice for Subclassed UIComponent and DataProvider
Back to your problem. If you're not seeing the combo box's dataProvider
populate or update, then it's a binding problem. Good idea to try the
BindingUtils, but it's easier to fix the binding events in the model. If
you're using a getter / setter in the model, for the facilities collection,
make sure that the binding event is dispatched in the setter. If you're not
seeing the collection update, when existing items have been changed elsewhere,
then listen for the COLLECTION_CHANGE event on the facilities collection, and
in the listener function, manually dispatch the collection's binding event
(same as the one in the setter). If this doesn't work, look further upstream;
in the service, delegate or controller. You'll find the short.

[flexcoders] Re: Flex 4 data management - how do I approach this?
Hi Henrik, So you're getting back a collection of products from the service and binding them to the DataGrid. Let's assume that the product objects are Product Value Objects. You have every thing that you need for an order except for the quantity of the product(s) to order. Keep it simple, add a Transient field to the Product VO and use that for the quantity column in the same DataGrid. [Transient] /** * The product quantity to order */ public var productQuantity:int = 0; The itemEditor in the DataGrid can then just update the quantity property directly in the Product VO. The next step is to take the Product(s) that have a quantity and submit them to become an order. Usually the user can select multiple products for an order, so I'll go that route. After the user has entered all of the product quantities to order, the Products in the ArrayCollection are ready to be processed into an order. The user clicks a submit button; or you do this when the individual quantities change. For each (or one) Product in the ArrayCollection that has a quantity 0, create an OrderDetail VO from the necessary Product properties; including productQuantity. You might prefer OrderContent VO since that's the table that you're updating on the server. Add the OrderDetail VOs to an ArrayCollection and send the collection to the service; to process and create an order. Or, you can send a single VO; if that fits your needs better. The php service can create the order and then add the details to the order from the submitted collection of or single OrderDetail DTO. That's a simple round trip. Good luck. -TH --- In flexcoders@yahoogroups.com, henrik.hedberg hen...@... wrote: Thanks for the reply, this is what I did to get it to work so far: I created a value object class to hold exactly the data I wanted for each row in the datagrid.

That array collection I then bound as a dataprovider for my datagrid. I put in an inline item renderer for the amount with a numeric stepper. The next step will then be to take the correct data from that array collection (item id and item amount) and transfer it to a php service that will save it in the order-table of the database.

I would design my item editor with a textfield with a focus out event listener. When the event fires, grab the ID, amount and price and populate a value object. Add this object to a custom event and dispatch it. At the same level of the datagrid (Or wherever), have an event listener for the custom event. When you get it, add the value object to an orders array collection. If the user commits to buy, send this array collection to the server to populate the orders database.

[flexcoders] Re: Could not resolve * to a component implementation.
The point is that creating 2 files in the same folder, with the same case-sensitive name, is ambiguous. When you import one of the files into a component, how do you suppose that the compiler would know which one to use? It doesn't matter if its a file or class or interface or whatever. The compiler can't read your mind; yet :) Your approach of abstracting the view script code out of the view is a good idea; especially for unit tests.

[flexcoders] Re: dispatchEvent import
Hi Marco,
That does look like a problem. The dispatchEvent() method is available
for any UIComponent subclass or any class that extends EventDispatcher.
So, if you're going to use [Bindable] properties in the presentation
model, you would want to have the PM extend EventDispatcher:
import flash.events.EventDispatcher;
public class UserPresentationModel extends EventDispatcher
{
private var _currentState : String;
[Bindable( currentStateChanged )]
public function get currentState() : String
{
return _currentState;
}
public function set currentState( state : String ) : void
{
_currentState = state;
dispatchEvent( new Event( currentStateChanged ) );
}
}
This will allow you to bind the property to a view.
For events that you want to [Mediate], you would use the injected
dispatcher:
[Dispatcher]
public var dispatcher:IEventDispatcher;
dispatcher.dispatchEvent( new Event( myEvent ) );

[flexcoders] Re: Setting UI components in a composite component to private?
Hi Nick,
The best option is to create your composite components in Action Script. This
gives you direct control over the scope of the children, and they can be
referenced within the component by the name of the var. For MXML composite
components, if you don't give the children id's, they won't be public. This
can be tricky if you're used to referencing the children inside the component
by their id's, but you can usually rework logic like that to rely on events,
like click and change, instead of references; since events have a reference to
the target or currentTarget.

It is true it uses pure CPU rendering on Macs and both sides blame it on poor cooperation of the other side. I think, maybe one valid point that he makes is that Adobe didn't invest to much into mobile market until very recently... and, to be honest, flash rendering may be more optimized... like using platform available graphics tools - be it DirectX or OpenGL. It is also true that flash is kind of stuck in it's development... well, the language hadn't seen any significant change in years... But I don't think that what Apple cares about is how flash performs... not is it at all familiar with the situation around the product... For example I have Adobe tools to develop for flash on my Windows installation, but on Linux I have only non-Adobe tools, which is more by accident, but, anyway, this kind of contradicts what he says about non openess of the platform. I also think that the main profit from banning other popular development tools like .NET and Java from Macs Apple may hope for good revenues from selling their development tools... Think about that due to iProducts popularity the popularity of Obj-C grew a lot. It was a marginal language in terms of penetration until iPhone... So, they may hope to build a community of developers, who would develop in this language and thus became dependent on Apple's tools and the entire ecosystem... well, just like there's a lot of C# programmers in the world, not because it's the best language ever, but because of the demand. I think that Mac world sees the surrounding world from the entrenchment level, it's like after all those years! they are going to win one marketing war. They won't think about that their victory may turn into much larger loss on a general scale. Like, what good will come out of promoting obsolete technologies like HTML and JavaScript? And that's after it's been proven many times that the disadvantages are inherent to the technology and it is probably seeing it's last years... Well, for me going back to making web apps in HTML and JavaScript would be like dark ages comparing to any technology, not necessarily Flash, that offers compiled language and better integration with the native API... There may be to many marketing factors involved, of which I have little knowledge... and this may sound out of place... but, what would be if Abobe have cooperated with projects like HaXe and GNash? Or, offer to download the SWFTools' AS3 compiler along with Flex / Flash Builder? Or, at least bring their existence to the public attention somehow. What I'm saying is, this will not be a turning point in this pure battle of commercial interests, but, maybe it's a good time to put the plans of world domination aside and invest a bit more in the technical aspect of things?

[flexcoders] Flex 4 State Names and Binding
Hi All,
Unlike Flex 3, it seems that Flex 4 doesn't allow state names to be bound to
constants anymore. An example that no longer works would be something like
this:
mx:State name={ MyNavigationConstants.STATE_OPEN }/
While I appreciate the improvements that have been made to Flex 4 states, this
can be a problem for MVC oriented navigation frameworks. Just wondering what
the rational was for making this change.
Thanks,

[flexcoders] Re: Handling dataProvider of ComboBox on another navigatorContent
An easier approach than using these events, is to bind the ComboBox selectedIndex property to a variable like: [Bindable] public var myComboBoxSelectedIndex : int; that lives in the same class as the data array. When you get or initialize the array, set the variable to the desired value, and the binding will automatically display the correct item in the ComboBox. This way, you don't have to worry about timing. If the ComboBox exists, when the variable changes, the selectedItem will change then. If the ComboBox doesn't exists when you set the variable, when the ComboBox is instantiated the binding will kick in then. -TH --- In flexcoders@yahoogroups.com, Ivan ivan.ilija...@... wrote: I have TabNavigator component with two navigatorContent components.

Polling the twitter service every 60 seconds (refresh) would be a way that you could get updates semi-automatically. You're not using RTMP, so you're never going to be really live.

for the series. Here's some code for getting individual values and for
calculating totals for the week
private function dtFunction( o:HitData ):String
{
var seriesId:String = LineSeries( o.element ).id;
var seriesIndex:int;
switch ( seriesId )
{
case s0:
seriesIndex = 0;
break;
case s1:
seriesIndex = 1;
break;
case s2:
seriesIndex = 2;
break;
default:
break;
}
var totalBooksForWeek:int = 0;
for ( var a:int = 0; a 3; a++ )
{
var sessionBooks:int = o.item.session[ a ].books;
totalBooksForWeek += sessionBooks;
}
var s:String = b + LineSeries( o.element ).displayName + /b\n;
s += bBooks:/b + LineSeriesItem( o.chartItem ).yValue + \n;
s += bBook rate:/b + o.item.session[ seriesIndex ].bookrate +
\n;
s += bStatus:/b + o.item.session[ seriesIndex ].status + \n;
s += bTotal Books for All Sessions:/b + totalBooksForWeek + \n;
return s;

file the additional child nodes that correspond with that
datapoint.
I
feel that I am very close and missing one piece. How can I
accomplish
this dynamically by displaying the correct data for the series?
Note, I
can have more than 1 series in the XML data file.
private function DTPFunction(o:HitData):String
{
//WORKS for data that is used on the chart x and
y
values
//var s:String;
//s = b + LineSeries(o.element).displayName
+
/b
\n;
//s += bBooks:/b +
LineSeriesItem(o.chartItem).yValue + \n + bBook rate:/b +
series. o.item.session.bookrate + \n ;
//s += bStatus:/b + o.item.session.status
+
\n
;
//END WORKS
var s:String;
var a:int=0;
var fNode:XML = chart.dataProvider[0];
if ((LineSeries(o.element).displayName) ==
fNode.child('sessionname'))
{
s = b + o.item.session.sessionname[a] +
/b
\n;
s += bBooks:/b + o.item.session.books[a] +
\n +
bBook rate:/b + o.item.session.bookrate[a] + \n ;
s += bStatus:/b + o.item.session.status[a]
+
/size\n ;
a++
}
return s;
}

[flexcoders] Re: Updating renderer properties
Sure, but you don't necessarily need a model to use a VO; it can just be the strongly typed object that the dataProvider uses for its items. If you then change the transient properties of that VO, the set data method of the itemRenderer will work out of the box; and you can then adjust the renderer. You're right in feeling dirty having an itemRenderer reference a model. But reacting to changes in the data is fine.

[flexcoders] Re: Updating renderer properties
We're not so off really, I hear what you're saying. Now we're getting a better idea of the use-case. In this case, all of the itemRenderers need to be controlled the same way; by changing their styles and/or labels. So let's go up a level. Extend the List, or whatever. Both the dataProvider and the collection of itemRenderers are there, so you could do it either way from the parent. For the styles, I'd still try the StyleDeclaration routes. For the labels, you have to ask, are the labels data related, like from a table somewhere?. Are they related to the parent object of the data in the dataProvider? Or, are they constants or persisted values? Each case could have a different solution. One way, is to create a public var in the itemRenderers, or a getter/setter, if you want to do something when the value changes. So, the itemRenderer's label.text is bound to the public var. In the extended list you create a method to update all of the public vars in the itemRenderers. It's a loop, but not so bad. Make your extended List's method public. Or, you can also use getter/setter vars, if you wanted to bind out further. When set, they could trigger the method that updates the itemRenderers. Or, you can always use owner as List, in the itemRenderer to check the value of a public var in the parent List during updateDisplayList(), and set your label's text value there. Like I said, it's usually all about the use-case. In general, I don't see a lot of itemRenderers that all display the same thing; unless the data happens to be identical. Common labels are often pulled up to the parent component. And the manipulation of an itemRenderer, for me, is usually based on data properties; that make sense to be included in every item. Interesting discussion. -TH --- In flexcoders@yahoogroups.com, Aaron Hardy aaronius...@... wrote: I think there might be a misunderstanding. If it's a transient property on the data objects that come through the data provider, I would have to change the property for all the objects in the data provider to be the same value since I want all the renderers to change in the same way. For example, let's say all my renderers say Woot: and then the data's text value. Then at runtime, the user, in a different part of the app, enters Niner into a text input and therefore I want all my renderers to now say Niner: and then the data's text value. In my case, the word Niner really has nothing to do with the data, it's almost more about the style of the renderers--or what the renderers look like around the actual data. If I were to use the transient property of the data provider objects, I'd have to loop through all of them and set the property's value to Niner. I'm not sure if that's what you were suggesting, but that seems dirtier to me than referencing a separate model from the renderers. I'm interested in understanding your analysis of this though even if we may disagree in the end.

{date:new Date(2009, 3, 5), balance:95}
If I have an event for 1/1/2009, I can look up that the balance was 100 on
that day and place the event widget at [1/1/2009, 100]. However, if I have an
event on 1/15/2009, from looking at the data provider above, I know that the
balance was still 100, but because the line is diagonally vectoring towards
the next value of 140, my data point is misplaced if I put it at [1/15/2009,
100].
Is there a way to get the line's y value given an x value?
or
Can I change my line chart to not draw diagonal lines and instead draw square
lines so I won't have this problem?
