Flex :: Disable Databinding In MXML?
Aug 14, 2010
When the Flex SDK converts MXML to actionscript it generates a lot of databinding code. I don't want to bind a variable, for example if I know the variable will not change.
I can't seem to find a work around in Flex to disable the autogenerated databinding. Also, I was hoping this might also help with some of the runtime warnings thrown by databinding. To get around them, I sometimes use the following, which only throws syntax warnings (and don't appear in my console at runtime).
Syntax warning: Data binding will not be able to detect changes when using square bracket operator.

the new TextInput component which uses stagetext on 4.6 has this issue where if you bind a variable on it e.g
view1...
and i push a new view e.g view2, and pop it, hence reloading view1. on initial load, I can see that the textinput display the variable abruptly then the text vanishes afterwards..
I'd like to note that the variable is a stored data, and can be access on any view.

I need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change. I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.

Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?

I am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"

well, I have a combobox which I have bind his selectedItem property to a value object object, like this
<fx:Binding source="styles_cb.selectedItem.toString()" destination="_uniform.style"/>
<fx:Declarations>
<fx:XML id="config_xml" xmlns="" source="config.xml" />
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:ComboBox x="66.15" y="63.85" editable="false" id="styles_cb" dataProvider="{config_xml.styles.style}" />
the value object is a custom class with some setters and getters, and I want to set a property based of the value of the selectedItem of the combo, so inside the value object I have something like this
[Bindable]
public function set style(value:String):void
{
_style = value;
trace(value);
}
my problem is that each time I change the combobox selection which in fact change the style property of the value object it does it 3 times, if I trace the value of the setter it actually do the trace 3 times, why?? how can I avoid this? I'm doing something wrong? or there is a better way to do it,

I have creating a distributed note taking application in flex, it basically is a notepad I can keep in my desktop tray. When I add notes and goes back to a server and saves it in a database.
To am struggling to design the application correctly, I want to have a Syncing service that polls the webserver for changes and updates an Array of Note objects. The problem is that my note corresponds mxml component, aka SingleNote component. There are four different cases when being, a. a note is updated from the server poll, in that case I want to singlenote to update the settings b. a note is added to the array from the server, in that case a new SingleNote needs to be created c. a SingleNote is added from client, in that case a Note is added to array, and sent back to server d. a SingleNote is change from client, in that case the Note is updated in the array and sent back to server
The properties are SingleNote(Width, X, Y, Text).

I'm trying to set up a form that presents a combobox when an ArrayCollection it's bound to has several items, and doesn't present one when it's empty or only has one item. I've tried doing this by creating this class, but unfortunately, the data provider I've bound to is never not empty at the time the setter executes.
public class ComboboxOrFail extends ComboBox

public function ComboboxOrFail()

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

This is a project I'm working on for a simple demo tutorial application in Flex. I am using mxml pages. You can see to the left that I will have my main application and then other mxml files (In the Examples Package) as the examples that will be loaded into the main application mxml. How can I dynamically pull the value from the object in the list to load the child mxml file into the container that I have further down in the application?

I would like to include an MXML file in my MXML file in the same way you can include an external file in AS3 using the include directive. Using the include directive brings the code from the external file into the original file at compile time placing it in the same scope. For example,
Application.mxml:
<Application>
<source="external.mxml"/>

I was wondering if it could be possible to create a databinding system in pure actionscript without using mx.binding.utils At least I would like to know what is the overhead of the databinding code and how exactly the ChangeWatcher knows when a property has been changed.

What I have is a class with static properties that I want to use as images. I would like the images to be configurable at run time but still have the defaults. So the Images class looks like:
[Code]...
Clicking the button will change the static property in the Images class to something else. The image defined in the MXML will get the binding event and update the image, but the custom component created in ActionSctipt will not be updated.

I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.
