Re: [flexcoders] Cairngorm Question

2006-01-16 Thread Robin Hilliard
Hi YJ,

RocketBoots is working with a development team on a large (100s of  
classes) Flex 1.5 Cairngorm application at the moment with  
potentially many instances of the same "sub-application" (we call  
them workspaces) around at the same time - e.g. two searches, three  
articles, a calculator etc.

Here's our solution, which is working nicely.  Each type of workspace  
has it's own viewHelper class.  Each workspace instance has it's own  
viewHelper instance.  Because there are multiple instances it was  
going to be difficult to use the ViewLocator and ModelLocator, so we  
didn't.  Instead, when workspace instance X broadcasts an event, we  
include a reference to the workspace's viewHelper in the event data.   
The command's execute method caches this viewHelper in an instance  
variable, and its onResult method uses the same viewHelper to display  
the results.  The viewHelper instance also holds our model, using  
instance instead of static variables (although we can imagine using  
statics in some situations, for bits of the model shared across all  
workspaces).

Happy to answer further questions about this approach - this one has  
been in the backlog of things to blog for a while.

Cheers,
Robin

[flexcoders] Re: Question about a book written by Steven Webster and Allistair McCloud

2006-01-16 Thread Dave Wolf

You are really simply better off reading a plan old J2EE book.  Just
go to Amazon and find one that includes a section on security. 
Honestly this stuff has nothing to do with Flex.  Its purely a J2EE
thing.  Flex just seamlessly comes along for the ride ;)

I did promise you to post entries to a web.xml which will "secure" an
entire web application (and hence you could secure your Flex app). 
Here you go.  You can paste the following code into your web.xml. 
Please do keep in mind This is assuming you have already added 

1) Some user
2) Set their password
3) Placed that user into a Role called "user"

See, in J2EE those three actions are container specific.  So I cant
tell you how to do it for every container.  My guess is you use JRUN
(Integrated Server) which I don't use, so I'm not much help

Anyhow, add this to web.xml after the servlet-mappings:


Example Security Constraint

Protected Area
/*
DELETE
GET
POST
PUT


user



BASIC
Example BASIC-Based Authentication Area



user


When you now hit the web-app you will get a J2EE BASIC challenge to login.

var request:URLRequest  = new URLRequest(url);
__snd.load(request);

RE: [flexcoders] DateField: selectableRange

2006-01-16 Thread Deepa Subramaniam










Setting the selectableRange means only the dates between
rangeStart and rangeEnd (or in your case from rangeStart onwards) are
selectable – that is why the calendar starts at rangeStart upon startup.
There’s no way to select a date earlier then rangeStart. If you want to
keep the range of dates open and just disable some ranges from being selected,
then look into setting disabledRanges.

 

Upon making a selection in a DateField, when it is re-opened
it will remain at the date last selected. If you want to keep the calendar at a
particular selected date when the app is re-loaded, you’ll have to write
a mechanism where that selected date is stored somewhere and re-set when the
app is loaded again.

Hi - 

You can set whichever range property you want
(disabledRanges which disables
single or multiple days or selectableRange which
sets a range of dates which
are selectable) in ActionScript or at the tag
level. Both those properties
take an Object which contains two properties -
rangeStart and rangeEnd which
are Date objects. For example:

rangeEnd: new Date(2006, 1, 16)} }" />

Will make it such that the DateField enables the
range 1/1/06 to 1/16/06 as
selectable. 

In your case, you'd want to do: 

Date(2004,4,1)} }"/>

[flexcoders] Flex2 Custom Component Event

2006-01-16 Thread Rich Kroll
Hello all,
I'm new to this list and am glad to join the community.  I've been working
with flex 2 and have run into a problem I'm hoping someone here might be
able to help me solve.  I'm dispatching an event in my main mxml file, and
need to have it be captured within a custom component I've created.  The
problem I'm having is that the custom component is created numerous times
from within an  so I can't seem to attach the listener in the
correct fashion.  Here is a snipped from my main app:



import mx.collections.ArrayCollection;
import flash.util.trace;

public function broadcastShowType() {
dispatchEvent(new Event("showType"));
mx.controls.Alert.show("broadcast show event");
}








Then within my component I've got: 


private function initComponent() {
addEventListener("showType", handleShowType);
}

private function handleShowType(event) {
Alert.show("Received Event Notification");
}


I assumed that putting the addEventListener() within the component would
create it when the component was created, but it seems to be a local
listener, and will not receive events from the main app.  Considering the
dynamic nature of how I'm creating the custom component, is there another
way to add the event listener and have it able to respond to the outer
events?

[flexcoders] can not have separate flex war apps?!?!?

I'm having a wierd problem when trying to have different

The code will fail to compile 
 
Error 
/com/sf/sfv4/view/sharkfin/AddGoal.mxml:74 
Expected object definition or binding _expression_ inside 
mx.controls.Label
 
This does not occur when it is the only one web application /war. This 
only occurs when I have separate web application (each with their own web.xml 
configured to use flex). This is occuring in jboss 3.2.7.
 
 
Has anyone else had problems when using flex in multiple 
wars?

Re: [flexcoders] How to add an MXML component which is not in the root folder?

2006-01-16 Thread Martin Wood
right, well i was only referring to as3 files, but i built a simple test 
following the same technique and using mxml files and it works fine.

I had this setup

Project : Test (The 'library project')

Image.mxml

com/test/Image2.mxml

both mxml files are just simple image tags

Project : Test2 (The main project)

Test2.mxml

In Test2 I right clicked the project node, selected properties then in 
the classpath tab in the build path section I added the Test project as 
a folder (it showed up as ${DOCUMENTS}\Test)

Then in the Test2.mxml I could access both Image and Image2 from Test.

for Image I just declared



and to access image 2 i added another xmlns declaration to the 
application tag :

xmlns:test2="com.test.*"

Re: [flexcoders] How to add an MXML component which is not in the root folder?

2006-01-16 Thread Martin Wood
ah, hello..

like i said, i could only get it to work using the classpath settings, 
not the project reference panel.

but i dont think i actually did it with mxml components, i think i just 
used for pure code classes.

let me check and get back to you...

thanks,

Martin

I don't have the book's index in front of me, but I know a good web 
resource for such topics:
http://www.macromedia.com/devnet/security/

It sounds like you'd have a serverside database in there somewhere, 
which would then provide values to either your Flex app, or your 
audience's Macromedia Flash Player, or both, so that general techniques 
of securing a serverside database would all apply... am I seeing the 
situation correctly...?

RE: [flexcoders] Re: best way to handle this ViewStack situation when loading

2006-01-16 Thread Gordon Smith










You shouldn't have to do anything special.
If you don't specify a creationPolicy, or if you specify
creationPolicy="auto", a ViewStack waits until the user switches to
view V to create the children of V.

Basically when the viewstack in initialized I create just the view
containers for each view in the viewstack, setting an initialization
flag to false.

Then when the change event gets fired on the viewstack I check that 
flag and dynamically create the children in the view at that point.

So in a nutshell the creation of a view in the viewstack is delayed
until the user actually switches to a given view for the first time.

Seems to work fine and the load time is very fast now.

RE: [flexcoders] DateField: selectableRange

2006-01-16 Thread Deepa Subramaniam
Hi - 

You can set whichever range property you want (disabledRanges which disables 
single or multiple days or selectableRange which sets a range of dates which 
are selectable) in ActionScript or at the tag level. Both those properties take 
an Object which contains two properties - rangeStart and rangeEnd which are 
Date objects. For example:



Will make it such that the DateField enables the range 1/1/06 to 1/16/06 as 
selectable. 

In your case, you'd want to do:

Re: [flexcoders] Cairngorm Question

2006-01-16 Thread Bruno Martins



Hi fowleryj,
 
Why have the same problem here. And one solution for use a diferents commands you have to use diferentes names for each application, beacause the FrontController add a listener in a single "static var eventBroadcaster. But if your application is realy big I recommend to you rewrite some classes in the cairngorm framework. For example you can rewrite te EventBroadcaster and FrontController classes creating a FrontControllerLocator. This FrontControllerLocator can be implemented like the ViewLocator. You set IDs for each controller and use this IDs to call the EventBroadcaster. Did you understood? I did the same with the services creating a ServiceHelper and a ServiceLocator, and this can help you to implements the FrontControllerLocator.

 
I hope that can solve your problems.
 
Let me know if it`s works and sorry for my poor english. 
 
Hugs.

Re: [flexcoders] Image with (per-pixel) alpha-channel

2006-01-16 Thread Robert Thompson



I simply want to add that this is a great question and I've also sought it.     The promise of this capability has not been properly documented even for an alpha phase.     Let's hope Jan and others like myself can get some proper help and hopefully examples in this area.     Most animations in fact in Flash 8 Pro, even MX and MX 2004, are actually optimized frame by frame PNG or even JPEG versus the promised Video alpha masking.     Speaking for myself, it would be sufficient for me to get an example of a simple frame by frame pixel by pixel example as Jan requests.     These days are full of products with over hyped promise; Adobe/Mac. (actually strictly Macromedia per Flash) has been the exception so I hope FLEX is as well.     -r        "Jan L. Nauta"

RE: [flexcoders] Cairngorm Question

2006-01-16 Thread Battershall, Jeff
I've only worked with some of the Cairngorm classes that were described
in the Flex book. You're going to have to have a local model for each
sub app instance.  Your event that is fired after the search being
complete can also contain instance data about the Sub app that called it
and update your local model with the returning data accordingly. That
way you can map the returning data to the calling Search instance, and
its associated parent sub-application.

When you invoke a RemoteObject you can stipulate where the returning
data is going to go using the returned pendingCall instance which can
point to a result handler which can be local to the calling search
instance, which in turn updates your local model.

var pendingCall =  myRemoteObject.myMethod(arg1,arg2,etc.);
pendingCall.resultHandler =
mx.utils.Delegate.create(mySubApp,myReturnFunction);

function myReturnFunction(event):Void
{
//update your local model instance here;
}

[flexcoders] Re: Having a little trouble with Tree control drag and drop Flex 2.0

2006-01-16 Thread sourcecoderia
[EDIT]

The code has an error:
  the line "dropparent.addTreeNode(dropLoc,item);" should read

dropparent.addTreeNodeAt(dropLoc,item);

Sorry for that.

The underlying datasource xml is being changed but not reflected in 
the tree. Also the modelChanged event is not being thrown on 
dragdrop, only once on load for the type "ADD_ITEMS" ??

Thoughts ?

[flexcoders] Having a little trouble with Tree control drag and drop Flex 2.0

2006-01-16 Thread sourcecoderia
This code adds the item but always at the end. Is there a bug in the 
tree control that is causing this or is it my total misunderstanding of 
the XMLTreeDataProvider

the Tree dataprovider is an xml type.

Every get node type function returns a XMLTreeDataProvider type.


private function handleDragDrop(event:DragEvent)
{
var dropTarget:Tree=Tree(event.target);
var items:Object = event.dragSource.dataForFormat("treeItems");
var dropLoc:int = event.target.getDropLocation(event);

var dropparent:XMLTreeDataProvider = dropTarget.getDropParent(event);
for each (var item:Object in items){
   dropparent.addTreeNode(dropLoc,item);
}
}

Any insight for this would be most helpful. I searched but found no 
examples.

[flexcoders] Image with (per-pixel) alpha-channel

2006-01-16 Thread Jan L. Nauta
Hi,

I'm starting with Flex and want to display an image with an alpha mask. So
I've got a 32-bit .PNG with alpha channel, but I can't get it to display
correctly. Flash seems to use the alpha channel in the image to dither the
image, i.e. yes/no select which pixel are to be displayed instead of
smoothly blending the image with the background. Any idea's how to get the
image to show correctly?

This is for Flex 2.0 alpha 1, and simply using the  tag.

Regards,

Jan L. Nauta

[flexcoders] Cairngorm Question

2006-01-16 Thread fowleryj
We have been developing a fairly large application using Flex 1.5 and
the Cairngorm framework, and have recently run across what could be a
large roadblock. Our application has many sub-applications the user
can choose to run from a menu in the main application. To implement
this we are dynamically creating the children the user selects in a
view stack. All of these sub-applications rely on a particular search
screen that allows the user to find a particular person in our
database. The problem is that the sub-applications are bound to the
selection the user makes in the search screen, and are all reacting to
the same events (which are broadcast from the search screen). We would
like the search screens to function as separate instances. For
example, if I broadcast a change event from the search screen, all of
the open sub-applications will catch the event and change all of their
displayed information to reflect that of the most recently selected
person. Our problem appears to stem from the way the EventBroadcaster
and FrontController are designed. All events are broadcast in the same
EventBroadcaster using the getInstance() method, thus everything is
listening for everything.

Can anyone who is familiar with the intricacies of Cairngorm propose a
way to deal with this problem? We would like to be able to return the
information about the selected person only to the sub-application that
invoked the search screen. Perhaps it is not possible to do this using
Cairngorm, and we would appreciate knowing that, too. 

If anyone has a different/better solution, we'd love to hear about it.

Thanks in advance.
