RE: [flexcoders] database question
You can simply do a select on the first 'id' if your query is ordered correctly, like: Select top1 id from table order by id desc Or there may be a function in access to return the latest ID. In MS SQL and MySql there are similar functions such as: SELECT LAST_INSERT_ID() AS lastInsertID FROM mytable Simply do another insert on the second table then.

RE: [flexcoders] Re: database question
You can do that in MS SQL with a trigger. Think of it as an event that fires when a condition is met. IE when table A gets a new entry, the trigger on the ID field will perform a specified script.

Hi,
First, make sure, in the Canvas tag, that mouseChildren=true. You can
also check in the drag event handler function if the currentTarget is a
canvas or not:
if ( !event.currentTarget is Canvas )
{
event.stopImmediatePropagation;
}
There are probably better ways to do this, but this is a quick fix.

RE: [flexcoders] Re: Creating exceptions to an eventlistener
Thanks for your help, I ended out picking up the string value of the element in
the listener:
var str:String = event.target.valueOf();
Then finding if it was the element I did not want the listener to work on.
if ( str.search(displayPeople) = 1)
Might not be the most elegant solution, but it works a treat.

You are using event.currenttarget but this always points to the current object

Try using event.target and that might help. I hope so.

Right, i see. :)
I did find it interesting that I could also do this and skip the metadata
tag in the popup:
Yep. You use that metadata tag when you want to expose the event to a
container component via mxml
(Eg.)
mx:Button click=handleClick(event) /
If you look at the source of mx:Button you'll see the metadata for the
click event.
I wasn't sure if you knew that so i didn't comment on it.
So you would use the metadata tag if you wanted to do the following.
Canvas
script
private function handleFormSubmitted(e:CustomEvent):void {...}
/script
MyComponent
id=mc
formSubmitted=handleFormSubmitted(event)
/
/Canvas
MyComponent would have the metadata tag declaring the name and the type
of the event it dispatches and then it appears in FlexBuilder as a hint.
This is pretty much the same as writing the following:
mc.addEventListener(formSubmitted, handleForSubmitted);
HTH.

Re: [flexcoders] AS3 - single-fire event listener
Matt Bennett wrote: Hi all, In certain javascript libraries I've used previously, there is the ability to create a single-fire event listener -- one that automatically removes itself as a listener immidiately after it has executed. I'd really like a generic solution that just involved an overridden 'addEventListener' function and an optional 'single-fire' argument. Hopefully someone out there has solved this problem already. In the mean time however, I tried a more simplistic approach - calling removeEventListener inside my listener function, so it runs once and then removes itself. I can't get this approach to work for anonymous functions though, because I don't know how the anonymous function can refer to itself. There doesn't appear to be anything useful in the Event object passed to the listener, the 'this' keyword refers to something else, and I don't know how to alter the scope with which the listener function is called. Does anyone have a simple way to acheive this? Many thanks, Matt. http://blog.iconara.net/2007/11/05/a-generic-way-to-remove-an-event-listener/ cheers, - shaun

Re: [flexcoders] Screen Refresh function??
Hi,
Dan Pride wrote:
Odd, actually I have to call it in both places in its entirety, then it works
fine. If I call the display from the double click, then fill from the
complete, it misses the selected.
But if I call it from both it works fine.
So if I do this am I always running it twice or just on the first go round
then its Complete ??
The creation complete will handle the case of the first time you edit.
That is, it fixes the original problem.
Creation complete will only run once. I'm guessing the
applicationScreens component is actually a ViewStack.
If so, this is what i think might be happening:
. The first time you edit your data the edit component has not been
created yet(it's lazily created by this line:
applicationScreens.selectedChild = locaScreen), so setting the data
doesn't work as expected(original problem of first edit not getting
data) due to the fact that the input fields don't exist yet.
. Then the edit component's creation complete event handler runs and
sets the data(so editing works the first time now).
. Next time you edit the data the creation complete does not run again
as the component now exists. So you still need to set the data in the
function that actually sets up the edit component(your original code).
Now you have the same code in two places; which is not what you want
obviously.
You should be able to check whats going on by using the debugger;
setting a breakpoint in the creation complete function and in your
displayLoca function.
There is another solution that might be suitable, but is probably not a
good idea. The viewstack has a creationPolicy setting that allows the
viewstack to create all of its children when it's created. Rather than
using the default lazy creation. This is often /not/ a good idea for
performance reasons, but it would mean that the original problem would
not occur and you could remove the code from the creation complete event
handler and go back to your original code.
So, your left with at least 3 choices:
a) Duplicate code and setting data externally on a component(current
solution).
b) Modifying the viewstack creation policy to create all children when
its created(easy but a performance hit).
c) The solution I outlined previously.
private function displayLoca():void{
applicationScreens.selectedChild = locaScreen;
locaScreen.selectedItem = locaGrid.selectedItem;
}
And something like the following in your edit
component:
private var _selectedItem:Object;
public function set selectedItem(o:Object):void{
_selectedItem = o;
if (_selectedItem) callLater(updateInputs);
}
public function get selectedItem():Object{

Hi all, The issue we were having was that passing a flex object to a cfc was fine. Flex: RO.methodName(Object); CFC: !--- map each flex object argument as a cfc argument --- cfargument name=flexObjectArgument1 type=string required=false cfargument name=flexObjectArgument2 type=string required=false ..etc (full post here) http://www.mccran.co.uk/index.cfm/2008/7/1/Flex--Coldfusion-Remoting-passing -an-Object-usefully So the object is passed into the cfc as a collection of arguments, works a treat. But it all goes wrong when you try and pass in something, and the object. IE: Var myName:string = Bob; RO.methodName(myName ,Object); So in the cfc I'd expect to say: cfargument name=myName type=string required=false cfargument name=flexObjectArgument1 type=string required=false cfargument name=flexObjectArgument2 type=string required=false ..etc But this doesn't work! The first arg is present, but the second does not map as it previously did! So: 1. Pass 1 object, translates as a series of arguments. 2. Pass 'something', then an object, different behaviour.

For instance: myImage.source=imageArray[0].source; The problem is, when I change image source there's a brief flash (no pun intended) when the image control updates - it seems to briefly show the background of the parent control (in this case a canvas with a solid color). This makes for a jarring transition between each image as it's loaded. I get the same effect even in the simplest of cases - just setting myImage.source explicitly, forgetting about the array. How can I update the source of an Image control without this strobing effect? Or am I going about it the wrong way? My Flex experience is limited to a few months of frontend UI development - lots of data binding and layout - and this is a new one on me.

I imagine that it's not setting to be all in the array the same premise

To try and clarify; i think your old premise objects are still bound
to the input fields, therefore all previously bound premise objects are
being updated still.
One option might be to use bindSetter instead. I guess the downside is
you need to write all those accessors.
FWIW I've never used this function so not sure if its right or not. Just

When the form displays I want to display different stuff based on whether a

Im calling the form component from the parent like this:

Now how do I access the properties of organisation inside the component

it displays?
You could set the visible attribute to false
OrgForm organisation={organisation} visible=false /
then in your function set it to true once your UI logic has executed.
[Bindable] //getter ommited.
public funciton set organisation(o:Organisation):void{
_organisation = o;
changeForm(); //changes visibility to true.
}
private var saveOrUpdate:String = Update;

Re: [flexcoders] Question about Cairngorm / UM extensions
Josh McDonald wrote: Guys, I don't actually use Cairngorm yet, but I've been reading a bit about it, and listening to the Flex show podcast (which is great btw), and I'm wondering how the callbacks work in Cairngorm / UM if your views are simply calling this.dispatchEvent() to announce the user's clicked the login button or some such, how does the view get the message when the call is complete? And if a view has done 3 different things that may fire off requests to the server, how does it know which one has completed, when dispathEvent returns bool and not any sort of token? I'm sure this is a stupid question, but it's been on my mind lately and the UM docs seem to be even worse than those for Cairngorm :) The model is changed by the result of the event handling and the views observe this. cheers, shaun

gabriel montagné wrote: On Tue, Apr 22, 2008 at 1:17 PM, shaun [EMAIL PROTECTED] wrote: The model is changed by the result of the event handling and the views observe this. That is the stock cairngorm way of doing it. In cairngorm, the FrontController is the only listener for all the cairngorm events. It keeps a table of commands to use for each event type. When the front controller listens to an event, it will run that command (which is the one that has all the logic packed in it to change the model). It's from the commands that you update the data on the models and all the view, which are bound to it, will respond. The UM Event extension allows you to send an additional callback object on that event (a callback being a couple of functions packed in an object, one for success, one for faults) so that you can bypass keeping data on the model that was going to be used just for letting the original view that dispatched the event that whatever process it initiated was finished.When the command has finished doing whatever it was that it was doing, it will run the callback function that will tell the original view I'm done. I see. So did they use an IResponder for that? It sounds a bit complicated but actually it isn't. The classic example is a login form.. from the form you pack a UserVO into an event and dispatch the event. Right there, from the view that dispatched the event, you disable the login form. Using stock cairngorm you would have to wait for the command to set a flag on the model that would let the view know that login process was complete. But this would mean that you have to keep that flag there for everyone to see when only the original view that dispatched the event needed it. Yes. Not very nice at all. Using the UM event, you can send a callback to the command... the command does it's thing and when it's done, it runs the success (or fault, if it failed) function on the callback, letting the login view know that it can re-enable the form or whatever without having to keep that data on the model. It sounds like a good improvement. Thanks for the clarification. cheers, - shaun

The Event.ACTIVATE event sorta works but only if u move focus out of the

any comments would be greatly appreciated, maybe even an alternative

I assume the problem you have is that not all the properties have been
set on the Object inside the constructor so you can't perform any
additional related object construction(ie) fetching another related
object from the DB hence wanting an event (FWIW there is not one).
If that is the case you can prob do somethign like:
private _barForeignKey:Number; //FK to Bar DB object
private var _bar:Bar; //Bar DB Object ref
public function set barForeignKey(id:Number):void{
if ( _barForeignKey != id) {
_barForeignKey = id;
dispatchEvent( new Event(Foo.BarFKSetEvent) );
}
}
[Bindable event(name=Foo.BarFKSetEvent type=Event)]
public funciton get bar():Bar{
_bar = fetchBarFromDB(_barForeignKey);
return _bar;
}
Or you can attach the listener and handler for the event
Foo.BarFKSetEvent in the constructor like you have in your example.
Perhaps, and this is a total guess, if you had a constructor that
matched the values for the SQL select it would use that constuctor and
your properties would be available in the constructor. However that is
a wild guess on my part and probably not the case as it would make
object construction from the SQL event more complex. Might be worth
trying though.
I assume it actully just does somethign like:
f = new Foo();
f.setBarForiegnKey(new Number(10)); // or whatever.

Re: [flexcoders] DataGrid limit on amount of records or data?
Hey Luke, Luke Vanderfluit wrote: The problem was that the data simply did not render. I tested with 2 different datasets, gradually increasing the number of rows in the database table. One dataset rendered correctly up to 4128 rows in the database. Then increasing the data with one row caused nothing (blank page) to be displayed. This was retried with a server (tomcat) restart and without in both cases the same result. No errors or debug messages. The other dataset showed the same behaviour however the cut off point was up around 6030 records. After I had reached the upper limit where no data was displayed ( a blank page) I shrunk the data back a few rows in both cases and reloaded the page with data displaying again. Perhaps your request timed out or something? FWIW I've loaded 50,000+ rows(with about 10-15 columns) into a datagrid before(just as an experiment) from an xml file, not generated from the DB. I suspect the problem is some sort of server side issue given that you received a blank page. HTH. cheers, shaun

Re: [flexcoders] Application doesn't hear my custom event??
Hi,
Its probably a good idea to (re)read the dev guide section about working
with events as it may help clear this up for you. The general problem is
that the VO is not part of the parent child hierarchy of the app so it
cant bubble up the chain.
Your globalVO needs to either (a) dispatch an event on the application
itself(not a good idea) or (b) your application needs to listen to the
globalVO. There are other alternatives aswell but these should be a help
to you right now.
(a) Application.dispatchEvent(globalChange); //or similar (in VO).
(b) globalVO.addEventListener(globalChange, globalVOChangeHandler);
Option (b) will mean your globalVO will need to be an EventDispatcher
subclass or have an EventDispatcher instance variable and a custom
method for attaching an event listener to the instance variable event
dispatcher(know what i mean?).
[snip]
GlobalVO.as
package com.test.reports.vo
{
import com.test.reports.events.GlobalChangeEvent;
import flash.events.EventDispatcher;
public class GlobalVO
{
private function dispatchChangeEvent():void{
var eventObj:GlobalChangeEvent = new
GlobalChangeEvent(this, globalChangeEvent);
var dispatcher:EventDispatcher = new EventDispatcher();
dispatcher.dispatchEvent(eventObj);
}
public function set someValue(val:String):void{
dispatchChangeEvent();
}
FYI. There is a property_change event(or some similar name) that makes
this pretty easy. eg)
class Foo{
var x:Number=0;
funciton Foo(){
addEventListener(PropertyChangeEvent.propertyChange,
handlePropertyChange);
}
function handlePropertyChange(e:PropertyChangeEvent):void{
if (e.property == x || e.property == y){
//do something.
}
}
}

[flexcoders] Unicode/Foreign Character Entry
Here is a control for allowing users to easily select special characters for entry in Flex text controls. Demo with Code http://www.capitalhcoder.com/ The basic idea is that by adding this control to your app and associating it with a text control, you can then use it to select unicode/foreign characters and add them to the text of the control. I asked about this here on flexcoders a while back and didn't get much response and I couldn't find much at all on the web, so I'm posting it in the hopes that someone might get a jump start from it in the future.

Re: [flexcoders] Re: Deep binding with Cairngorm question
Hi, This is not really directly related to Cairngorm, its about design. Disclaimer: The following is just an opinion. I'm not claiming to be a design expert. dbronk wrote: The problem with this solution is that it is assuming that the same class that is setting the prodList is also listening to it. Or at least it knows all of the places that it is listening to it. I may have several different classes listening to this list and each binding to a different function. How am object setting the prodList suppose to know how many / which classes / which methods are listening to this collection so it can remove all the listeners and then re-establish them all? Good point. I think its is a design floor to listen to an array that is a property of another object. Rather the owning object should be broadcasting events when one of its properties changes. Thinking of the arraycollection as an entity in its own right(a domain object) is probably not such a good idea IMO. Really, its just a datastructure that forms part of an entity. As you pointed out; the arraycollection can be reset and the other objects listening have no way of knowing that the arraycollection has been reinitialised (meaning the event handlers are no longer registered to the correct object). Therefore the bottom line is you can't reliably add a listener to that object without resorting to workarounds/hacks. Perhaps a better way to implement this is to have the the containing object expose add/remove/filter methods that manage its internal array collection. The containing object would dispatch corresponding events. Your listeners would be added to the containing object rather than the collection. If your owner object API contract was such that only a _copy_ or non-mutable version of the arraycollection is returned it means that adding/removing objects or listening to events directly on the collection becomes meaningless. A subclass of arraycollection that is non-mutable and throws and error when an event handler is registered may be helpfull to prevent mistakenly attaching handlers or adding to the collection. cheers, - shaun

Will you expand on this please? I did the following code hoping to
solve the issue, but I'm very worried this goes much deeper than just
ArrayCollections and goes to every object that has an event listener
on it. If that is the case I can't see how leaks can be stopped.
Use weak references, anywhere that you don't use weak references make
sure you remove the event listeners when your objects are discarded so
they can be GC. See the API for EventDispatcher.
I think you could have left your code as it was but used a weak
reference when adding the event listener. This should allow the
arraycollection object to be GC.
Basically I was suggesting to prevent a leak you could do somethign
along the lines of one of the following(untested code).
A)
public function set prodList(list:ArrayCollection) : void {
_prodList = list;
var isWeak:Boolean = true;
if ( _prodList != null){
_prodList.addEventListener(change, myfunc, false, 0, isWeak);
}
}//end
B)
public function set prodList(list:ArrayCollection) : void {
if (list == null){
if ( _prodList != null ) {
_prodList.removeEventListener(change, myfunc);
}
_prodList = list;
return;
}
if (_prodList != null){
_prodList.removeEventListener(change, myfunc);

_prodList = list;

Hi, ben.clinkinbeard wrote: Glad you got it working. Yea, its unfortunate (but unavoidable) that reinitializing a var kills the listeners. (Actually, I think reassigning like that could cause a memory leak, can someone confirm?) If its feasible you may want to replace those lines with prodList.removeAll() and then you should be able to get rid of Binding. Ben dbronk dbronk@ wrote: Second, swapping my mx:Binding with adding a listener on CollectionEvent.COLLECTION_CHANGE definitely did the trick, but with one bad consequence. If somewhere along the way code was written prodList = new ArrayCollection, it broke. My solution to that was to add back the mx:Binding, but when that fires, it simply runs a function that reestablishes the event listener on CollectionEvent.COLLECTION_CHANGE. Now it seems to work no matter how I set the list. I would have thought the old array collection would have been garbage collected because the arraycollection itself would no longer have any references to it. It would reference the handler function and the handler fucntion would reference the object it was declared in, but the array collection itself would be unreachable AFAIK. However, reading the docs for EventDispatcher it seems as though creating a new ArrayCollection could result in a memory leak. --- /langref/flash/events/EventDispatcher.html#addEventListener() If you no longer need an event listener, remove it by calling removeEventListener(), or memory problems could result. Objects with registered event listeners are not automatically removed from memory because the garbage collector does not remove objects that still have references. --- Probably the easiest thing to do would be to make the listener reference weak. Or, create an accessor function for the arraycollection and remove the listener from the old arraycollection and add a listener to the new arraycollection if they are not the same object. cheers, - shaun

I will say I've got a few beefs with Cairngorm and from just looking at the PureMVC diagram i already see a few solutions. I guess my main beefs with cairngorm has been the use of commands. Specifically in creating Re-usable commands. the 1 to 1 event-command-delegate methodology has never sat well with me. Dumb Models (vo collections) is another. I am wondering what makes you think that the CG models need to be dumb? Why can't your CG model be a domain model? Then a ModelLocator simply holds a reference to an object which forms part of a complex object graph.

Re: [flexcoders] Cairngorm vs PureMVC
Hey Bjorn, Bjorn Schultheiss wrote: It took me a while to grapple with but thats how it's been explained to me. VO's. Thats it. All logic is in the commands. Now excuse me if I'm wrong and I'll be happy to be proven so. Interesting, but that doesnt really meet the definition of MVC does it. I'll quote the Java BluePrints: http://java.sun.com/blueprints/patterns/MVC-detailed.html . Model - The model represents enterprise data and the business rules that govern access to and updates of this data. Often the model serves as a software approximation to a real-world process, so simple real-world modeling techniques apply when defining the model. As you can see that is quite different from the DTO/VO pattern(which should be used for coarse grained data transfer). I'll quote the Java BluePrints again: http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html . Clients usually require more than one value from an enterprise bean. To reduce the number of remote calls and to avoid the associated overhead, it is best to use Transfer Objects to transport the data from the enterprise bean to its client. In terms of event handling well, if a VO is Bindable is that the same? Do you mean listening to the view or commands? I do make by domain objects Bindable and non Dynamic. But I'll try and give a simple example of what I meant. My Model classes handle the propertyChange event so when a proprerty of the object changes I can set a dirty flag to indicate that the object has been changed and is unsaved. I also use event listeners on a collection object within a model object. Object A has many B objects(stored in an arraycollection in object A). When a B object is added to the collection, A should be flagged as unsaved. The A object needs to know when a B object has been added or removed so it can set its own dirty flag. Object A adds a changeevent listener to its arraycollection of B objects, A handles the collection change events dispatched by the collection of B objects by setting its own dirty flag. Right or wrong, this is an approach I have used in the past. I'll quote Jesse again. http://jessewarden.com/2007/08/10-tips-for-working-with-cairngorm.html 3. Only Commands set data on the Model; you can break this, just don’t if you can help it. In Model View Controller, only the Controller sets data on the Model. In this case, the Commands are the Controller (usually), and as such, setting ModelLocator data is their job, and their job alone. If data is getting f’d up, you immediately know it’s in the Command. You never have to question “who’s setting my data, where, and when?”. I think this type of rule might be more beneficial if you have a VO only model, as it makes sure your logic is in one spot, the command class rather than the view. So it seems like all the Event/Command classes have to be created to make up for the deficit of logic in the actual Model - where it should be IMO. It seems like the Command, which is meant to be a Controller? according to the quote above (although we have a Front Controller aswell! Whats up with that picture?) is playing the role that the model should be. Seems bogus to me.. :) cheers, - shaun -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Flex3 Beta 1 vs Beta 2 SWF file sizes - Debug code not removed?
I've been doing some experimentation with RSLs for reducing file sizes and I ran into something interesting. When I build my code with FB3 Beta 1, Hotfix 2.0.1, my output file size is 897kb. When I build the EXACT same code with FB3 Beta 2, Hotfix 2.0.2, my output file size is 1319kb. This happens to be the same size as the -debug.swf I get from Beta 1, which makes me think that FB3 Beta 2 does not remove the debug code from the swf it exports. Has anyone else seen this issue? Is there some new setting I need to be using? A workaround? Thanks, Shaun _ capitalHcoder http://www.capitalhcoder.com/

// Do a whole lot of stuff here.
// Including updating bound variables, etc.
}
// After if do the rest of my merge process.
}
My problem was that if I passed in true or false, it always went into
the true block of the if statement. So that is when I created my test
function of crazy. So let's forget about that test function
(although, there were not dup names. One var is s, the other is ss).
So, my function has several things it will be doing inside of the true
portion of the if statement, and then whether or not it was true or
false, continue with other processes. After creating my crazy test
function I then came back and modified my function to:
function filter(includeBase:Boolean) : void
{
if ( includeBase )
{
// Do a whole lot of stuff here.
// Including updating bound variables, etc.
}
else
{
// HACK FOR AN APPARENT BUG!
// Not sure why, but this if statement will always resolve to
true unless there is an else.
var whoKnowsWhy : String;
}
// After if do the rest of my merge process.
}
Once I did this, my code works great. includeBase of true and it will
go into the true block. includeBase of false and it will go into the
false block.
I find this very very hard to beleive. I'm betting you changed the way
your exercising the code (ie) by passing in an explicit false or true to
the function.

Nice one Seth.
Here is another solution that uses the namespaces. Note: the xml:lang is
changed to the aaa namespace(so i used that in the e4x) but I'm not sure
why that happens(i noticed it when i traced the xml).
//Create the default namespace.
var ns:Namespace = new
Namespace(http://www.skype.com/go/skypeweb;);
//Create the aaa namespace that is used instead of xml:lang.
var aaa:Namespace = new Namespace(http://www.w3.org/XML/1998/namespace;);
function creationComplete():void{
var xml:XML = //assume it exists..
doIt(xml);
}
private function doIt(xml:XML):void{
//Set the namespace!
default xml namespace = ns;
trace(+xml.status.presence.(@aaa::lang=='en')); // Away
}
cheers,

It's fine. Which code behind approach do you use Tom?

RE: [flexcoders] does flex2 has coldfusion cold hint?
I always edit my cfc's in DW. I normally also write a cfc_test.cfm. this file is a good test for the cfc itself, its suprising how many errors you think are flex related, and they aren't they are cfc problems.

Hi Mike, Mike Morearty wrote: [snip] (b) If don't want Flex Builder to launch the browser at all, but just connect to a browser you already launched manually: This is a hack, but it works: Go to the same launch configuration dialog mentioned above, and just set the URL to any old thing (e.g about:blank, or if that doesn't work, http://www.google.com). When you click Debug, Flex Builder will launch a browser at the bogus page; and now, for the next two minutes, Flex Builder is listening on a socket, waiting for the Flash player to connect to it. Just ignore the bogus browser, and go over to the browser you wanted, and load your swf. When the Flash Player starts, it will connect to the socket that Flex Builder is listening on. - Mike Morearty Adobe Flex Builder team Thankyou very much for the information. Its a huge help to be able to run the debugger like this. Especially after an app has been integrated into an existing system (requiring a session id and other parameters being passed into the flex app). I started using this yesterday and was overjoyed. :) Thank again. - shaun
