[flexcoders] automationName in Components
Hi,
I was wondering if it is possible to dynamically set the automationName
property of a control at runtime?
For example, if I have a component that contains a label:
MyComponent.mxml
mx:HBox
mx:Label
id=label
automationName=componentLabel /
/mx:HBox
And I want to include more than one instance of this component in a single
application:
mx:Application
MyComponent /
MyComponent /
/mx:Application
How can I write MyComponent such that each instance of label has a unique
automationName? Is it possible to dynamically provide a automationName for the
label? So my component would then look like:
mx:HBox
mx:Script
public var labelAutomationName : String ;
/mx:Script
mx:Label
id=label
automationName={ labelAutomationName } /
/mx:HBox
And I would use the components like so:
mx:Application
MyComponent labelAutomationName=label1 /
MyComponent labelAutomationName=label2 /
/mx:Application
Is this possible?
Thanks
Mike

RE: [flexcoders] RemoteClass
Have you strongly reference the com.beans.Sale class in your Application? Your
RemoteClass meta-data looks fine, but if you've not got a hard reference to the
class inside your flex app, it won't be compiled in to the SWF and won't be
mapped correctly at runtime. You can get round this by just adding an unused
variable somewhere of type com.beans.Sale. (there maybe a more elegant way to
get round this).

Subject: [flexcoders] RemoteClass
Hi all,
I have a Java service that returns an ArrayList of type Sale.
At the Flex application I also have the type Sale, the simplifyed
version is this:
package beans
{
[Managed]
[RemoteClass(alias=com.beans.Sale)]
public class Sale {
public var id:int;
public var customer:Customer;
public var product:Product;
}
}
Although, when I trigger the RemoteObject to retrieve the ArrayList of
Sales (ICollectionView at client), Flex seems to be treating it as a
collection of Object, not Sale.
Is this conversion (Object - Sale) to be done automatically? What's wrong?
thanks

[flexcoders] createChild with dynamically loaded classes
Hi all, Im having a very specific problem with createChild calls that I will try to sum-up as briefly as possible: A.SWF loads B.SWF through a Loader component, both are originally flex applications. A invokes a particular method on B, passing down an instance of Panel. In this method, B tries to perform a createChild call on the passed panel, using a class definition contained only in B and not in A. This results in a HTTP request being made (http://localhost:/WebApp/[type%20Function]) looking at the Flex source, this seems to be the result of an attachMovie call returning undefined, causing a call to loadExternal from within the createClassObjectWithStyles method in the View class. The documentation for MovieClip.attachMovie (http://livedocs.macromedia.com/flash/mx2004/main_7_2/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Flash_MX_2004file=1487.html#3998340) seems to suggest that what Im trying simply cannot be done (without including a reference to the class to be created within A.SWF, which defeats the purpose of this slightly). From the documentation comments: chi chi latté said on Feb 16, 2005 at 2:52 PM : I was having problems attaching symbols into mcs loaded dynamically using loadMovie(). Somebody's written above that it's not too easy... No screen name said on Oct 6, 2004 at 1:42 AM : Anyone know if the movieclip used in the attachmovie call must belong in the current clip's library? (and not the library of an external swf) It doesn't seem to attach them if this is the case. JohnGrden said on Nov 5, 2004 at 7:44 AM : Yes, the linked clip MUST be in the library of the clip calling attachMovie. Well you can do it without too much bother. If you are using loadMovie(), and you're attaching clips into it and out of it, just make sure the symbol is in both libraries (being exported in one swf, and imported in the other), and place the imported symbol onto the stage of the swf which does not have the symbol native to its library. That make sense? Note: you _have_ to place it on the non-native stage. Setting it as imported in the library is not enough. I put them hidden for one frame. This is really useful if you've got a big project of several swfs, and you want to attach some common mcs into the loaded swfs. Hope that helps+is not too garbled mspres said on Mar 10, 2005 at 12:57 PM : Note: attachMovie() WILL work with shared asset symbols unless the movie is loaded into another movie. For example, consider that assetsUser.swf uses attachMovie() on shared asset symbols imported from assets.swf. This works fine until a third movie, assetsUserLoader.swf is used to load assetsUser.swf. Preloading the assets.swf with assetsUserLoader.swf does not solve the problem. The only solution is to include design-time instances of the shared asset symbols on assetsUser.swf stage; which, defeats the reasoning for using attachMovie. The root of this bug and its various symptoms span across many topics. Can anyone confirm this definitely cannot be done, and there is no work-around? (Note that debug statements show everything else up as being ok, the method on B is invoked, the class definition is visible, the parents panel reference is fine, Im 99% sure its the attachMovie call that is returning undefined). Any advice, suggestions etc greatly appreciated. Thanks in advance! (Code samples can be provided if it would help).

RE: [flexcoders] Re: Question about Enable / Disable Validator
From a cairngorm View Helper you should usually use syntax like: mx.validators.Validator.disable(view, modelName.elementName); There isnt really a current document in flex, the first argument you need to provide is just a reference to the document that the mx:Model you are validating against was declared on.

[flexcoders] Creation events and view stack children
Hi all, a quick question about view stack instantiation: If I have a view stack, creation policy auto, with two children: mx:ViewStack creationPolicy=auto components:ChildOne / components:ChildTwo / /mx:ViewStack ChildOne.mxml: mx:HBox creationComplete=trace(child one created) !-- stuff in here -- /mx:HBox ChildTwo.mxml: mx:HBox creationComplete=trace(child two created) !-- stuff in here -- /mx:HBox In what order are the creationComplete events fired for the children? I seem to be witnessing behaviour where the creation complete events are being fired immediately, when the view stack is instantiated, but the actual components within the children are not being instantiated until the selected index of the view is changed (as you would expect from creationPolicy=all). Does this sound reasonable? Has anyone experienced this kind of behaviour? I was under the impression that the creationComplete event for the top-level components themselves would not fire until the view stack index changed. (Apologies for the lack of a complete code sample (spread across several files Im afraid), but hopefully what Ive said is enough to explain the problem) Cheers, Mike. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com YAHOO!

Help with a custom component
Hi all.
I'm looking for some help with custom components. Basically, I have done
a bit of a hack and managed to get something that appears to the user as
an editable date field, by placing a TextInput over top of a DateField
control and capturing the required events (see attached for the code).
Its ugly, but it seems to work to a certain extent. The problems start
when I try to incorporate validation in to the test page. Placing a form
item with required set to true around the component along with a
validator tag doesn't seem to perform the necessary validation.
Sometimes typing the date directly will run the validator, but the
hidden DateField seems to be the component that changes color.
Basically, what im asking is:
* Can this approach be adapted to include validation from the
parent application that uses the component?
* Or, is there an easier, more elegant way to provide an
editable date field? (The docs indicate editable property inherited
from ComboBase will be ignored)
Cheers,
Mike

Basically,
I have done a bit of a hack and managed to get something that appears to the
user as an editable date field, by placing a TextInput over top of a DateField
control and capturing the required events (see attached for the code). Its
ugly, but it seems to work to a certain extent. The problems start when I try
to incorporate validation in to the test page. Placing a form item with
required set to true around the component along with a validator tag
doesn#8217;t
seem to perform the necessary validation. Sometimes typing the date directly
will run the validator, but the #8220;hidden#8221; DateField seems to be the
component that changes color. Basically, what im asking

Hi Jimmy, I wasnt actually aware of the unregisterView method on the view helper! After adding this, the problem seems to be solved (cheers Steven).

Using this method the components problem is also solved as the view can be registered through action script with the view already exists error being caught, and just reassigning the view attribute of the existing view helper to point to the existing instance of the component. Add a forceRegister method to the view locator that will not perform the check for an existing view, write myown view helper class that will override the set name method and call this method. This method is obviously not ideal. Cairngorm is a solid framework and things like existing view helper checking exist for a reason. Any thoughts/suggestions? Cheers, Mike Herron
RE: [flexcoders] newbie
Hi,
This is an issue that I have also had to
deal with recently.
I had limited success using code similar
to that which you have outlined below. The major problem is that pressing CTRL
+ the majority of keys causes the browser to intercept these key presses and
perform its own actions. Trying ctrl + almost every key on the keyboard
resulted in only getting about 6 or so CTRL + key combinations being made available
to me. Trying ALT + key was even less successful as the flash player just
seemed to loose focus entirely, with the browser menu then being given focus.
Has anybody else had any success with key
board shortcuts? At first glance, it doesnt seem to be possible to
provide logical keyboard navigation on forms with more than a handful of
controls. Of course, tab navigation is still possible.

Hi,
1) Yeah, you can trap the keyboard events using
ActionScript. You can use
keyDown event with Key object tofind
about pressed keys.. See example
code later in the mail.
2) you can use the combination of mouseDown,
mouseMove mouseUp event to
make dragging happen. Look at Manish's Google map
example, see how he is
dragging...

Hi members,
I am new to Flex
coding. I did learn a lot from coenraets web site
and also from richinternetapps.com. I do really
appreciate them for letting
others to see their code and learn from it.
I do have couple of issues to resolve. I didtry
search on Livedocs and
other websites for solutions but didn't findany.
1) Can any one
programmed hotkeys(keyboard shotcuts) in flex ? for
example, instead of using mouse to click on tab of
TabNavigator container
users can use keyboard shortcuts say Ctrl+T or
Alt+T something like this.
There will be a problem using Alt as accesskey
because Alt key has been used
for windows hotkeys. Please help.
2) My user requires
that they should be able to zoom a scanned image
and then move/drag that image. I did accomplished
zooming part but unable to
drag the image. Here is the mxml file for your
ref.

Thanks in advance.

RE: [flexcoders] Cairngorm and deferred instantiation
Steven, Take your point, just wanted to see if there was anybody else that had come across this or found any different solutions. Not wanting to get the view helper on demand was just a small point of style, it just made sense to get the view helper in the constructor. Like you said though, clarity before brevity.

The command classes in turn will use the view locator in their constructors to get the view helpers they need. So even though the command hasnt been called and doesnt actually need to use the view; it is still trying to get an instance of the required view helper. Sorry if im not making this totally clear! Like I said, the other solution is to only get the view helper instance when the view is required, i.e. in execute(), onResult() and onFault(). The perfect solution? Cairngorm components with completely self contained services, controller and view locators wouldbe fantastic ;) Seriously though, I do see your point, it is an architectural problem that needs more thought. Sorry for the lack of details, I can write up a fuller description if required. Cheers,

RE: [flexcoders] Cairngorm and deferred instantiation
Thats certainly a workable strategy, but from a design point of view the separate tabs (in reality a view stack but works on same principles) are really applications within their own right and I would like to be able include them just by passing their root mxml name. Also, children will be added at run time to the view stack using the create child method so I dont want to have to defineall the required view helpers for applications that may not be loaded. Looks like I will have to use the view locator 3 separate times in the execute, onResult and onFault methods From: Dimitrios Gianninas [mailto:[EMAIL PROTECTED] Sent: 17 February 2005 16:00 To: [EMAIL PROTECTED] Subject: RE: [flexcoders] Cairngorm and deferred instantiation Hi, Put the ViewHelper(s) at a higher level, I use TabNavigators and ViewStacks in several places in my UI, but I do not have a ViewHelper per tab/stack.

Cairngorm Event to Command
Hi all Just a quick question about using cairngorm: In my application when a product has been added, I wish to broadcast a product added event and have it picked up by two separate command classes that will update two separate views. Unfortunately, when the event is broadcast, it only seems to be picked up by the command class that was registered last in the controller. To get round this I am having to broadcast two separate events specific to the two views once a product has been added. Obviously, this doesn't provide as high a level of de-coupling as I would like. Has anyone else come across this problem? Am I doing something wrong or is this a know quirk? Cheers, Mike
RE: [flexcoders] Cairngorm Event to Command
The command classes already exists and work in their own right for their
respective views. I will not always want to update both the views at the
same time.
You seem to be getting confused with the purpose of the event. The event is
broadcast once the product has been added, not when the product is required
to be added. I then want to be able to specify in my front controller:
addCommand(productAdded, new CommandToUpdateViewOne());

Not sure why it requires to create a new command class.
onResult function in your command class that is assigned with add product
event would be something like
public function onResult( event : Object ) : Void
{
var view1ViewHelper =
ViewLocator.getInstance().getViewHelper( view1 );
var view2ViewHelper =
ViewLocator.getInstance().getViewHelper( view2 );
view1ViewHelper.doSomethingInView1();
view2ViewHelper.doSomethingInView2();
}

Yes that would certainly work, but that would involve creating a new command
class. I was wanting to re-use the command classes that are currently being
used, but just fire them both for the same event.
Although your solution does seem more elegant that broadcasting multiple
events.

I presume nothing prevents you from accessing two different views via
