Re: [flexcoders] Mostrar todas las filas de un DataGrid sin necesidad de scroll

[Alberto Albericio]

Alex, you understood it very well hehe Let me answer him in Spanish...

Como dice Alex, puedes utilizar la propiedad rowCount para conseguir esto:



Observa que utilizamos rowCount vinculado a la longitud de nuestro 
dataProvider + 1, suponiendo que tienes visibles las cabeceras del 
datagrid. Puedes omitir este +1 si tienes las cabeceras ocultas.

[flexcoders] Cast Exception from FDS to Hibernate

[Alberto Albericio]

Hi all,

I have an hibernate mapping defined with some properties and a relationship:


 
 


This relationship is defined in the java bean as:

private Collection items;

On the Flex side, I'm receiving this relationship as an ArrayCollection. 
The serialization from java.util.Collection to Flex ArrayCollection 
works fine but, when I try to save the changes made on the client side ( 
what, on the server side, gets translated into 
getHibernateTemplate().update ( .. ) ), it just fails throwing this error:

java.lang.ClassCastException : flex.messaging.io.ArrayCollection cannot 
be cast to java.util.Set

Im stuck and I dont know what to do. Any ideas?

Thank you!

Alberto

[flexcoders] ValueCommit strange behaviour with comboBoxes

[Alberto Albericio]

Hello all,

Whenever I try to change the selectedIndex in a comboBox, if the 
selectedIndex is different from the current selectedIndex, it dispatches 
2 valueCommit events instead of 1!! If I change it to the same index, it 
just dispatches one! :o

Here's an example:

http://www.adobe.com/2006/mxml"; layout="vertical">








Is this a bug??

Thank you in advance

Re: [flexcoders] Binding from Actionscript

[Alberto Albericio]

Hi Ralf ! Im fine thank you! ( I will mail you personally at gmail )

Thanks for your help. I finally got that binding working! Paul sent me 
some stuff (same stuff posted in flexcoders I think) and "with some 
time" I managed to make it work.

In summary, I was creating the binding in the wrong place. I was 
creating the binding in the class constructor and creating it in the 
"createChildren" protected method made the trick, and the binding was 
not a binding to a display object! :/ It was a binding from an object in 
the model to a setter function in the class.

Anyway, thanks to everyone and specially thanks to Ralf and Paul in the 
EMEA Adobe Consulting team.

Cheers,

Alberto

[flexcoders] Binding from Actionscript

[Alberto Albericio]

Hello all,

I have an MXML component that has an mxml binding to a setter function 
like this:



and a setter function defined :

private function set handleDestroy( destroy:Boolean ): void {
  // some code 
}

This works 100% but I need to create this binding in an actionscript 
component; I have tried the following:

BindingUtils.bindSetter( handleDestroy, model.podManager.getPod( 
this.mypodId ), "destroy", false );

and having the same setter function. It complains about the setter 
function. If I remove the "set" keyword (on the setter function) it 
compiles but does nothing ( the binding doesnt seem to enter the function )

How can I create this binding from actionscript? Can someone give a 
working example on how to create a binding to a setter function in 
actionscript? It should be easy but I have found no documentation at all 
on this. I need the help of an expert.

Thank you very much.

Alberto

[flexcoders] Identifying a RTMPFlexSession

[Alberto Albericio]

Hello all,

In FDS,

Im trying to maintain a list of open RTMPFlexSession sessions on the 
server; Im using the events FlexSessionListener.sessionCreated and 
FlexSessionListener.sessionDestroyed for that. That works but I can´t 
identify what client belongs to what session. Method getUserPrincipal() 
on those events always returns NULL ( Im using custom authentication and 
JRUN 4.5 )

On the client side, properties of consumer.clientId and consumer.session 
are always NULL.

Is this a bug? How can I identify every client? Any ideas?

Thanks

Alberto

[flexcoders] Samples and JRUN

[Alberto Albericio]

Hello all,

Is there any rational explanation on why Samples of Flex2b2 are working 
in the integrated version of JRUN but they just dont work in my 
production environment where I run a JRUN 4.5up6?

I just copy the working folder to the production server and nothing 
works. I delete every .swf so that he recompile things again.. but still 
nothing works? Has someone run into this issue?

Thank you all in advance

[flexcoders] Image source path bug?

[Alberto Albericio Salvador]

Hi all,

Im experiencing an strange behaviour (bug?) with the Image tag in 
Flex2b2. If I use the tag like:  it works 
when compiled with Flex Builder and the image displays correctly.

If I move this application (and picture) to j2ee server, I type the url 
in the browser and the application runs but no image is displayed.

A simple application like this : [testImage.mxml]

http://www.adobe.com/2006/mxml"; xmlns="*">



does not show any image (only a broken image icon) when accessed through 
: http://./testImage.mxml

But, If I run this sample using Flex Builder it works fine. And if I run 
locally (not through a browser) the generated swf at the j2ee server it 
works fine. And accessing that same swf through the web browser, it does 
show that broken-image icon!

Is this a bug?

Thanks in advance

[flexcoders] How to extend a radiobutton component?

[Alberto Albericio]

Hi all,

I want to extend the RadioButton component so that it becomes something 
like:

the radiobutton itself + something else (vbox, canvas, ...)

How can I do this? Right now, Im trying this:

http://www.macromedia.com/2005/mxml"; xmlns="*"
selected="{mySelected}"
>











The Script code works, it is extending the component fine but the visual 
"addon" is not working, I mean that HBox.

It is important for me to extend the radiobutton component and not 
create a new VBox with a radiobutton on it because im creating these 
components from a Repeater and it should behave as a RadioButton.

Any ideas?

Thank you all.

Albert

[flexcoders] BackgroundImage options

[Alberto Albericio Salvador]

Hi all,

I use backgroundImage to set a container's background but is there any 
property to repeat this background to fill the whole container? 
Something like the "background-repeat" CSS attribute or the "background" 
HTML attribute.

Re: [flexcoders] Dynamic UI question

[Alberto Albericio Salvador]

I think I cant use the Tile* components because they resize their tiles 
to the same width and height: resizing one tile will resize all the the 
rest.

Since I want a vertical list, can I use the List component to create a 
list with one checkbox on each item and expandable content for each item 
whenever I select that checkbox?

[flexcoders] Dynamic UI question

[Alberto Albericio Salvador]

Hi all,

I want to create a vertical dynamic UI and Im currently trying 2 approaches:

1)  

2)
 
   
 

This is working ok in both cases BUT my myThumbnail.mxml component is 
somehow resizable wheter the user selects a checkbox or not:






In approach 1, a scrollbar appears if I select the checkbox of any of 
the repeated objects instead of resizing the item at the TileList and 
show the full component.

In approach 2, the Tile item resizes fine only If I select the checkbox 
at the first position. If I press the checkbox at the second, It resizes 
the second item and  also resizes the first one!

Basically, Im driven myself mad trying to make this working. Has anyone 
a working example on something similar? A vertical repeatr component 
with expandable items? or what am I doing wrong?

Thanks in advance

[flexcoders] Cairngorm and memory administration

[Alberto Albericio Salvador]

Hi all,

When using Cairngorm (usually for middle-large developments), lots of 
events, services, commands, etc start to move behind the scenes:
new Delegates, new Events, etc... so my question is, when are these 
objects removed from memory?

Imagine I have a screen that loads products depending on some options. 
Each time these options change, I must recall the products load that 
means:dispatching new event with new options (new event), passing 
control to the command, then to the bussiness delegate (new delegate), 
etc...

So, if I want to display products depending on 10 variations of these 
options, I must use the same mechanism to get the new product list... 
thats 10 new delegates, events, etc on memory? What if I set to Nothing 
the new Delegate created after each use?

Re: [flexcoders] Dispatching events from cairngorm viewhelper

[Alberto Albericio Salvador]

Hi Alex,

I stopped playing with ViewHelpers in the 80% of the cases. I was 
overloading the use of ViewHelpers and thank God I soon realized of 
that. To make more reusable components, I prefer embeding script code 
into the mxml file, use reusable commands (this was discussed in another 
thread) and dispatch events from the same component.
Talking about the other 20% of cases, I use your (and some other guys) 
approach of dispatching events from the parent view or the main 
application that both extend display objects.

Thanks again for your help and please read my new post about Cairngorm 
and memory Im just writing in a sec hehe

[flexcoders] Binding using Boolean expressions

[Alberto Albericio Salvador]

I rewrite my post because it got mixed into another thread (same 
subject) , sorry.

Hi all,

I dont know why, but the Flex compiler alerts some error when I try to 
use binding with 2 arguments:


...


where:

private function isThisVisible():Boolean {
   if (someCombo.selectedIndex != 0 && someOtherCombo.selectedIndex != 
0) return true;
   else return false;
}

Why and how to solve this so I dont have to fill my code with these 
functions?

Re: [flexcoders] Cairngorm2 reusable commands

[Alberto Albericio Salvador]

Hi Joao,

I dont agree at all hehe For me, it is ok that commands know about views 
(or whatever dispatches the event that started that command)

Imagine this situation:

You have a screen where 2 components ask for the weather on a zip code, 
so I can see weather on 2 locations at the same time. What I say is:

I need both components to dispatch the same event("getWeather") but with 
different parameter (zip code) and get the results back to them using 
the same command. I dont want to use a single application pool to store 
my results.

[flexcoders] Cairngorm2 reusable commands

[Alberto Albericio Salvador]

Hi all,

In Cairngorm commands, I always define statically where I want "some 
results" to be sent (normally a custom function in component that 
extends ViewHelper). This updates my view and works fine. But...

How can I make that command Class to send "some results" to whatever 
asked for them (who dispatched the event that threw that command)?

Eg:

foobar1.mxml and foobar2.mxml
..
public function setResults(someResults):void {
//update my controls
}

public function getResults():void {
dispatchEvent("askForResults");
}


foobar1 and foobar2 dispatch the same event and the command needs to 
know where to send back the results and run setResults on the 
corresponding caller. How can I achieve this?

Thanks in advance

Re: [flexcoders] Binding refresh

[Alberto Albericio Salvador]

Hi Jonathan,

If your're working with Flex2, try using an ArrayCollection instead of 
an Array. The Array class does not throw any event on change to update 
such controls anymore.

Using the ArrayCollection instead of Array, that do not update controls

[flexcoders] Flex2 combobox performance

[Alberto Albericio Salvador]

Hello all,

I've noticed that performance of mx:ComboBox is really low. I mean, when 
using a Flex2b1 combobox component, expanding its contents gets lagged, 
not fluid. Has anyone else noticed this behaviour?

Re: [flexcoders] Dispatching events from cairngorm viewhelper

[Alberto Albericio Salvador]

Joao,

Im using cairngorm 2a2 and my event extends CairngormEvent but the 
problem is not with the event but with dispatchEvent method:

Im meaning, in this function, LocalidadesEvent extends CairngormEvent

public function getPoblaciones(cp:String):void {
var event : LocalidadesEvent = new LocalidadesEvent(cp);
dispatchEvent(event);
}

But I get the error:

Call to a possibly undefined method 'dispatchEvent'

Im using the same code in the main view and in the helper and it should 
work, but it doesnt.

Dirk,

I have chosen your second approach and it works fine: thats letting my 
view to dispatch the event.

Thank you very much

Re: [flexcoders] Dispatching events from cairngorm viewhelper

[Alberto Albericio Salvador]

Hi Joao,

Im working with Flex2b1 and I dont import anything, neither in the main 
view nor in my custom viewhelper.

Anyway, importing that continues throwing the error:

Call to a possibly undefined method 'dispatchEvent'

[flexcoders] Dispatching events from cairngorm viewhelper

[Alberto Albericio Salvador]

Hi all,

When trying to dispatch an event from a custom class that extends 
cairngorm ViewHelper, I get this error:

 >> Call to a possibly undefined method 'dispatchEvent'

Firing the event from a function of the main view, same code, it works fine.

My function is something like, same in the view and in my custom viewhelper.

public function getPoblaciones(cp:String):void {
var event : LocalidadesEvent = new LocalidadesEvent(cp);
dispatchEvent(event);
}

Has anybody run into this issue?

[flexcoders] Automatic layout positioning

[Alberto Albericio Salvador]

Hi all,

When defining non-basic "form" layouts, I need sometimes to hide/reveal 
extra information or editable areas. When doing this, I need the rest of 
the form to automatically rearrange, similar to setting the 
document.getElementById("foobar").style.display = "none" or = "" in HTML.

If I try to use the "visible" property in Flex, it just hides/shows the 
UIcomponent but it does not rearrange anything.

Is there any trick or official procedure to emulate this behaviour?

Thanks

[flexcoders] Cairngorm ViewHelpers

[Alberto Albericio Salvador]

Hi,

When using Cairngorm 2.0a2, how can I make use of the ViewHelpers?

Trying to attach a viewhelper to the login example, I write this class:

// loginViewHelper.as
package org.nevis.cairngorm.samples.login.view {
import org.nevis.cairngorm.view.ViewHelper;
import mx.controls.Alert;
public class loginViewHelper extends ViewHelper
{
public function loginViewHelper() : void
{
}
public function sayPo() : void
{
mx.controls.Alert.show('Popopopopopop');   
}
}
}

What am I doing wrong here that the compiler is arguing about Cairngorm 
ViewHelper.as and Cairngorm ViewLocator.as?

Thanks

Re: [flexcoders] Sending complex data to java services

[Alberto Albericio Salvador]

Hi Matt and thanks for your reply.

I decided to stop using VO's to send/receive data to/from my services 
since it was too "hard to code", replicating classes, etc...
We are currently sending AS objects from Flex and receiving them as 
flashgateway.io.ASObject in the service side. These services are also 
returning this type of objects that Flex understands nativelly.

Greetings,

[flexcoders] Sending complex data to java services

[Alberto Albericio Salvador]

Hi all,

[Flex 1.5]
Im building a form driven application using multiple mxml files. Each 
mxml has control and validation over the data retrieved from its UI 
components. Now, when the global form is valid (each mxml is valid on 
its own) I want to submit everything as a single parameter to a java 
service. So my question is: what is the best choice to send this data?

The java service needs to collect this data, build a valid XML and store 
it into a database.

My first approach was to send the data as a ValueObject: I wrote some 
classes for each mxml model (to get validators working) and then send a 
ValueObject with X elements representing each model.

Thank you in advance

[flexcoders] Data service results format: VO or XML?

[Alberto Albericio Salvador]

Hello all,

I have read some posts on how to pass data from the service tier to the 
Flex tier using VOs or arrays of VOs. I dont think it is a bad idea to 
use these objects but:

Is it possible to return results in XML format and then bind parts of 
this XML "document" to Flex UI components like a datagrid, list, etc?

This would be something like :
// not real code
1) myDg.dataProvider = event.result.getElementsByTagName("prices")
   and then:
columnName="PRICE"
colomnName="another attr or subelement"
   ...
2) myList.dataProvider = event.result.getElementsByTagName("shops")

and even more advanced :

3) myDg.dataProvider = event.result/[EMAIL PROTECTED] < 200]

Thanks all

[flexcoders] DividerBox question

[Alberto Albericio Salvador]

Hi all,

In a dividerBox component, how can I fix the size (height or width) of 
one "block" of the divider not be less than X? I mean, when autoLayout 
is true, I can move the slider and hide "blocks". I want to set a min 
value for each block to prevent "loosing blocks".

Thaks in advance

Re: [flexcoders] Binding question

I forgot to mention Im adding items at the beginning of the array, at 
position 0. So the ModelLocator.SOMEARRAY[0] is always the last item added.

[flexcoders] Binding question

[Alberto Albericio Salvador]

Hi all,

When I bind a text label to the first position of an array like this :



The text shows the first item of the array correctly. 

When I add a new item to the array, the text of the label does not 
change so it seems the binding is not really working.

I know Im adding items to the array correctly because I have a list 
bound to ModelLocator.SOMEARRAY and it's working fine.

What am I doing wrong?

Thanks in advance

Re: [flexcoders] Strange List behaviour

[Alberto Albericio Salvador]

Hi,

I need to add the item only once. I cant add the item then reverse the 
Array because my array is bound to a component and that would make the 
component to "redraw" :)

[flexcoders] Custom Component builder

[Alberto Albericio Salvador]

Hi,

I want to create custom components extending original Flex components, 
is there any visual application for this purpose? For example, I want to 
create my customPanel which extends mx:Panel; I want to add a title bar 
with buttons and icons, set event to these buttons, etc...is there any 
application to do this or I must use AS to create them?

Thanks

[flexcoders] Strange List behaviour

[Alberto Albericio Salvador]

Hi all,

Im using a List component to display the messages incoming from a "msg 
push server". The dataProvider of the List is bound to "some array 
variable". If I use the method *addItem* to inject data into the array; 
as a result of this action, the List grows downwards, leaving the first 
element always visible and loosing the last added msgs lost (gotta use 
the scrollbar to find them at the end). Well, I want the List to grow 
upwards so that the last incoming msg gets displayed the first. I use 
the *unshift* method but the array does not get modified. So, what is 
happening here?

I know this is not a natural Flex question but I cant find why it is not 
working the way I want.

Nuke this post if you feel this is not the right place for it and sorry.

Got it. I have it working now and fits quite fine in the Cairngorm

Re: [flexcoders] Re: Cairngorm question

[Alberto Albericio Salvador]

Hi again,

Im trying to create a business delegate class for handling a connection 
to, for example, an xml socket.

When trying to delegate onXML to the responder it keeps on saying there 
is not such property on the responder, but of course there is. If I 
define the function inside de business delegate class, it works 
(changing responder.myOnXML for myOnXML, of course)

I have something like this on my command class:

class org.nevis.cairngorm.prexon.commands.SubscribeCommand implements 
Command, Responder {
   public function execute( event:Event ) : Void {
var delegate: SubscriberDelegate = new SubscriberDelegate( this );
delegate.subscribe( );
}

public function myOnXML( event : Object ): Void {
mx.core.Application.alert("RESPONDER OK");
}
..
}

And the business delegate has:

this.responder = responder; (the parameter for the class)
myListener.onXML = Delegate.create( responder, responder.myOnXML );
...

What Im I doing wrong? Is it okay setting a responder here? Cause I have 
to define a result and fault handler im never using for this kind of 
services...

Re: [flexcoders] Re: Cairngorm question

[Alberto Albericio Salvador]

Hi Alex,

I like the idea of "Listeners" and they way you point to manage server 
pushes injecting events and data to the Cairngorm architecture. Mainly 
because server pushes are treat just like if they were data from a 
user-gesture.

If possible, send me a sample code for one of these "Listeners", just a 
short one so I can see how to initialise the subscription and how 
handlers for server pushes are defined. I can imagine it's somehow 
similar to a business delegate class calling a remoteobject but I dont 
see how to leave these services "in the background" listening and 
waiting for server pushes.

Thanks for your help Alex.

Re: [flexcoders] Re: Cairngorm question

[Alberto Albericio Salvador]

Thank you Daniel, if no more suggestions/corrections are done, I will 
take that choice.

Of course a recovery plan was planed plus de mute option is also welcome. :)

[flexcoders] Cairngorm question

[Alberto Albericio Salvador]

Hi all,

The Cairngorm samples are a great resource for understanding how to best 
arquitect an specific kind of applications; in this case, applications 
that talk syncly with some servers that expose some services.

Imagine now that Im building an application which implements, somewhere, 
some kind of asynchronous services: a flash comm server chat , for 
example. This "service" must be running, in the background, even if im 
visually working in another part of the application, entering some data 
for new providers or whatever. So the question is, where is the best 
place to initialise these services? Or how can I place/work with these 
services within this arquitecture?

My choice would probably be to initialise evrything inside a 
"initialise()" function in the model locator and then use some public 
var there to control msgs and status of this "service" and then bind the 
chat components to these vars.

I hope someone can help chosing the best option.

Thanks all in advance.

[flexcoders] Controlling iddle time

[Alberto Albericio Salvador]

Hi all,

If I want my Flex application to control the time that one user is 
iddling and launch an event if that time is bigger than X, how can I do 
that?

For iddling Im meaning the time the user is not even moving the mouse, 
or he is not focused on the application, etc

Greetings

Re: [flexcoders] Popup component

[Alberto Albericio Salvador]

Manish,

I know how to throw a component in a popup window using the popup 
manager. I was not asking that but how to modify view/Login.mxml 
component so that it was launched in a popup window. Imagine the 
original piece of code is part of the Index.mxml file, and Login.mxml is 
under the directory pointed by namespace "view", Login.mxml is basically 
a container with a helper class attached.

The question is: how can I modify the container or the helper class so 
that Index.mxml know it has to show this component in a popup window?

My lame solution to this has been replacing this:



with this:

   
 


and thus loosing the cairngorm structure because Login.mxml must reside 
in the same directory than Index.mxml (using "view:Login" instead of 
Login does not launch any error but the whole app screen gets white )

I know cairngorm is not just a file organization policy but I get the 
feeling Im breaking it somehow, dont you think so?

Greetings

[flexcoders] Popup component

[Alberto Albericio Salvador]

Hi all,

I have a question:

When I use a main viewstack like this:


 
 


Where view:Login is basically a TitleWindow... how can I make this 
component to be a popup component?

This short is extracted from the cairngorm login example. The example is 
ok, but I would like to know how can I make this login to be popup so 
that the user can drag the window acrosss the main screen, just like the 
windows login behaves.

[flexcoders] XMLsocket behaviour

[Alberto Albericio Salvador]

Hi all,

In my Flex application, I use XMLsocket to receive some server msgs.

onConnect, onClose, etc events work fine but, when I cant connect to the 
socket, how can I tell mySocket to try reconnecting every, lets say, 20 
seconds?

I want something like : .onNotConnected = function () { ... } every 20 
seconds :)

Thanks all in advance!

Re: [flexcoders] Flex, Remoting and more

[Alberto Albericio Salvador]

In some scenarios, what your telling it makes sense.. anyway, Im reading 
about what the "New Data Services" in Flex 2.0 will bring and I get the 
feeling I will be able to use these new features to get this working :)

Meantime, any other ideas are welcome.

[flexcoders] Flex, Remoting and more

[Alberto Albericio Salvador]

Hi all,

I've been reading about "connecting" flex client applications using 
Flash Communication Server(FCS) and shared objects. Thats seems to cover 
the needs for developing chat-like applications...
Now, imagine I have an external "Notification server" (yukon 
notification server, or whatever) And I want FCS to listen 
*persistently* to this server. With FCS and Remoting I know how to POLL 
a database "1 time or every 10 seconds" and format that answer to feed 
the FCS but HOW can I create a persistent link to a notification 
server,socket server or similar, get the data this server is pushing, 
format this data and pass it to the FCS?

So basically, I want to know how to replace POLLING with PERSISTENT 
LISTENING.

Example application: A Flex application that shows the queue of  a call 
center. When a new call arrives, it is shown in every client running the 
application. And it is the call center notification server that tells 
the FCS it has received the new call and NOT the FCS that polls the 
queue of the notification server to see if there is any new call pending.

Thank you mates!

[flexcoders] Steven Webster, I need help with Cairgorm

[Alberto Albericio Salvador]

Hi again Steven,

After reading some more about frameworks and related stuff after my last 
post on "What Cairngorm is?", I want to start developing using 
Cairngorm. I've been reading about synergyflex, which seems to be 
something similar to Cairngorm, but I get the feeling you are more about 
to help me starting with all this :)

So I basically need a step-by-step tutorial on how to code a simple flex 
application using primalscript (or any other environment) and Cairngorm. 
After this, I think I will be able to understand the cairngorm store 
application flow.

Thanks in advance

[flexcoders] What is Cairngorm? Flexstore vs cairngormStore

[Alberto Albericio Salvador]

Hi all,

I've been out of the flex world for 3 months and now Im reading about 
something called Cairngorm?
So what is Cairgorm exactly? What are the advantages of using cairngorm 
vs not using it?

I have installed the cairgormStore sample and seems quite the same thing 
as the flexstore one.

Thank all!
