Re: [flexcoders] Flash Player may be not creating Shared Object on Mac
Thanks Guy Morton. I have resolved my problem and the solution is as below. I got the latest flash player from the Adobe. I have Flash Builder 4.5 installed on My mac machine and when i launch the application via Flash Builder(standalone), it uses the internal Flash Player(debugger version) that was embedded with Flash Builder on Mac which fails to create the shared objects. I clicked project - properties, Flex compiler - checked HTML wrapper (at bottom) and then the shared objects were created.

[flexcoders] Module issue
I try load new module when previous one has been unloaded.
So I let the moduler load module in the unload event handler.
But the module can't be loaded ?
moduler.unloadModule(); // actually it has not been unload
moduler.loadModule(...); // the new one load
moduler.unloadModule(); // When It has been unloaded
modulerUnloadedHandler(e:ModuleEvent):void{
moduler.loadModule(...); // the new one load
// but the new one can't load with no error ~~~
}

Use the –keep-generated-actionscript MXMLC options and see the pile of code it

caused the combobox to be populated correctly. What I was really looking for
was what was going on under-the-hood for the code above when it is processed
during compilation into AS3. Does this MXML mean that there is assignment going
on in the constructor? (current results seem to point to 'no'), or does the
Flex compiler look at binding related attributes (surrounded by curly braces)
and translate those into a series of calls to BindingUtils.bindProperty()
I suppose I could have just downloaded the flex source and looked. :\

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.

You have the right idea; to encapsulate the dataProvider, validation and

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

I very much appreciate the help! Any chance I can take to improve the
design would be greatly beneficial, from a maintenance standpoint.
My feeling originally was if I have two comboboxes that are in entirely
different parts of the app, but that will always be populated by the same
data provider, always have the same validation and always utilize the
same change function (while being different from other comboboxes in the
site), it made sense to encapsulate the dataprovider/validation/change
events into the box itself so it could be added to a view without having
to specify all of the various attributes a combobox needs--since they are
not changing.
Initially, it seemed a bit pointless to write:
components:FacilityComboBox dataProvider={model.facilities} /
everywhere I implemented the Facility ComboBox since everywhere the
Facility ComboBox is implemented...the dataProvider is *going* to be
model.facilities and will never change.
If you think that there is a good example somewhere that demonstrates a
better design for this type of class hierachy, please point me to it and
I'll have a look. As the subject states, I'm very much looking for the
best practice here.

Validation can be abstracted just like dataProviders. For a combo box,
you only need to validate the selectedItem; from the view, presentation
model, or a common utility class. Most other stuff happens in
itemRenderers; that have a little more freedom. It may be that you're
locked into a structure that was handed to you, but hardcoding a
reference to a singleton model, from which you set the data provider of
a combo box from within the combo box, breaks the rules. If you're
having problems with binding the dataProvider to the model's property,
the binding problem is probably upstream from the combo box. Good luck

[flexcoders] adding and managing children dynamically - accordion
I was trying to build a component that would dynamically add NavigatorContent as children to an Accordion based on how many items were in an ArrayCollection. That worked I got the expected number of accordion tabs labeled correctly. I now want to add a DataGrid to each NavigatorContent. When I set a break point I do not see a reference to the NavigatorContent by the id that I set when they were added to the Accordion or anywhere in the component. How can I work with the DataGrid and set its DataProvider, etc? I will want to work with data in the DataGrid - crud I was trying to mimic what I had done using JQueryMobile with header tag and queries return to the cfm page. They have a collapsible content block that worked well on the small screen, but I need to be able to do more when a larger screen is available. Any suggestion?
Re: [flexcoders] Why don't horizontalCenter and verticalCenter work with Spark ColumnConstraints?
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.

Constraints are designed to be used to constrain other components for

[flexcoders] Axis Scale problem on Dual Axis Chart
I have a simply dual axis chart similar to the samples found all over
the internet. The chart has a line series on one Linear vertical axis
and a column series on another Linear vertical axis. The problem is
that when certain events in the application happen, the min and max of
one of the axis is reset to 0, 100. To avoid this I can set the min and
max values, but I would like to avoid this as the axis should auto scale
just like it does when it is first created.
Here is some sample code to show the problem. The code is basically a
chart with a button. When the button is clicked a new styleSheet is
loaded and it is then that the axis is set to 0, 100.
