Hi,There is a RESIZE event but...If you are actually creating a custom component, I wouldn't recommend attaching events that actually are going to effect your updateDisplayList() and commitProperties().
Ok, If a client calls width or height, you are going to get an invalidateProperties(), invalidateSize() and invalidateDisplayList().Lets see, the sequence would be...1) myComponent.width = 350;
2) myComponent.invalidateSize()3) myComponent.invalidateProperties()4) myComponent.invalidateDisplayList()5) myComponent.commitProperties()6) myComponent.updateDisplayList()
You will get this always.The trick would be to check your cached properties in commitProperties(), then if they have changed, switch a flag that says(as aggregated as you want) var baseCalc:int = blah;
if (baseCalc != cachedBaseCalc){ cachedBaseCalc = baseCalc; rightBoxInvalidateFlag = true}Then...In you call that happens next in the updateDisplayList() you now have a fine grained access point to only update the calcs that have changed.
IE updateDisplayList()If(rightBoxInvalidateFlag){ //redraw only right box since it's metrics changed rightBoxInvalidateFlag = false;}I hope that helps and doesn't confuse. hehe I develop some pretty big components and using events IN your component, well my opinion is nah don't do it. 
Use the framework Luke. ;-)Peace, MikeOn 8/23/06, tddclare [EMAIL PROTECTED]

[flexcoders] FlexBuilder 2.0 SDK plugin with IBM RAD 6.0?

2006-08-23 Thread Libby

Has anyone tried to install the plugin to RAD 6.0? When I try it tells
me wrong eclipse version. It looks like my RAD eclipse version is
3.0.2, but RAD 6.0 is IBM's latest and greatest. Maybe someone could
tell me how to install it successfully? Am I gonna have to run two
versions of eclipse? : |

A few things...

First I am working on a demo that will show the performance and
bandwidth differences between the various ways of exchanging data
between Flex apps and the backend.  I'll let everyone know when it's
ready...  Hopefully next week.

Second, the GZIP thing does work to reduce bandwidth, but you take quite
a hit on latency and server cpu cycles depending on just how much data
and how often stuff is passing through the servlet or apache filter.

In every case I've ever seen, RemoteObject significantly increases
developer productivity, significantly reduces bandwidth, significantly
reduces latency, significantly reduces server load, and significantly
reduces client cpu cycles.  This applies to REST, SOAP, and JSON.  With
the most significant benefits when compared against SOAP, since SOAP is
so verbose compared to the others.

[flexcoders] Variable Type for Web Service Result

2006-08-23 Thread Ethan Miller

Greetings -

Expanding on the Connecting to Web Services tutorial, I added a  
combo box for switching between methods of the API to the Adobe blog  
aggregator, ie from getMostPopularPosts to search.

As both methods return the same columns, the data grid displaying the  
result can stay the same, other than needing a different value for  
data provider, ie:

myWebService.getMostPopularPosts.lastResult
vs
myWebService.search.lastResult

I was hoping therefore to bind the dataGrid dataProvider value to a  
variable which I'd set when users change the value of the comboBox  
(which selects which method to use). However I think I'm typing the  
variable which stores the value of the service result wrong, as I get  
null whenever I try and set the value (blogResult), show below:

No. I have yet to run this app and see 300MB of RAM

When the GC runs it destroys objects within the
totalMemory within the player. When the player needs more memory for new
objects, it adds memory if the gc cannot dispose of what is needed. It is true
to say that on machines with ample resources, the player may accumulate more
resources but this is true with all applications.



I have to say I think you may be looking at a bug specific
to your os/system configuration. Is the behavior browser specific? 



Just to be sure: 300 megabytes = 314,572,800 bytes

I first noticed this issue while looking at the task

megs of ram. If I am running the app on a machine with less ram will the
browser use less memory? Is that what you are saying?

Ok
got some information for you:



flash.system.System.totalMemory
- The amount of memory (in bytes) currently in use by Adobe
Flash Player.



A
better way to think about this is allocated memory. When the player needs more
memory it acquires it from the OS/Browser in use. The player doesn't
necessarily give the memory back. Within that memory in use are the objects
being used. When GC runs, it disposes objects within the allocated memory but
doesn't give memory back to the OS/Browser.



The
GC is running and collecting objects, but f lash.system.System.totalMemory
is not the right way to see this happening.

This is a huge probolem on my app because it has like 30 Repeaters that are

I have an
application that uses many repeaters where the repeater's
dataproviders are constantly updated which redraws the view. All look
fine visually, however the flash player continues to use more and more
memory.

I created a demo version of this at
http://www.everythingflex.com/flex2/MemoryTest/

I have buttons which up the amount of repeater items and then lower
them and also attemp to delete the arraycollection, delete the
dataprovider, etc but the memory never is recaptured.

The source is also provided.

Does anyone know how to get the garbage collection to run when the
repeaters content changes??

RE: [flexcoders] Flash Data Services - help needed

2006-08-23 Thread Seth Hodgson

Hi Benjamin,

With regard to the exception, in your services-config.xml file you'll can find 
a channel-definition for an RTMP channel. The RTMP channel endpoint on the 
server is a socket server that binds to the port specified in the endpoint 
uri=.../ element. A single port can't be bound by multiple handlers, so if 
you have several FDS applications running on your Tomcat server you'll need to 
configure the RTMP channels across these applications to use unique ports.

Hope that helps,
Seth

Hi everyone,
 
finally i found the time to try out the data services. I`m using tomcat 5.5 and 
Java Open Transaction Manager form my basic setup.
I was able to run the samples that ship with fds but now when i try to set up 
my own projects i get stuck with some errors.
I get the following message from the tomcat logs:
 
Exception in thread RTMP-Server flex.messaging.endpoints.rtmp.RTMPException:

Let me say i`m not a server or java guy - so if anyone has an idea.
It would also be good if someone could point me to a basic tutorial for setting 
up fds and building a simple application - not based on the samples that ship 
with fds. 
For me it would be important to know how to configure the various configuration 
xml files in the flex folder. 
 
Thanx for any help

Re: [flexcoders] Re: custom component: how to tap into resize?




 
When components you are creating, framework you will want to use, no?I don't know if I understand exactly what you are asking but, if it is When I create components that are .as files and subclass a framework class, do I want to use the Template Method Pattern of the flex framework?
The answer would be yes of course.I would put it this way.If you are developing a car and you are an engineer, you would use the schematics of the car design, the way the car was engineered to run to add a specific add in subsystem in the internal workings of the car.
Now, If I was an outside company that created addd-ons for that car, I would use the 'macro' schematic verses the micro of the actual car engineering.The thought is, the tighter you integrate your design into the frame of the target, the tighter your component becomes and actually becomes PART of the car not an addon.
If I was creating an mxml component, I would tend you use events more because in my view, an mxml component is an addon not an inherent subsystem of the framework.I don't advocate creating anything in mxml that needs to be subclassed in the future because although it gets rendered into an as3 class, it is not extensible like an as3 class file because the development pattern differs in respect to creating a subsystem of the actual framework.
Anyway, rambling aside, events belong to clients. The framework belongs to subsystems of that framework. If you have a composite component(client of the component) inside your subclassed as file, by all means use events. Just don't use events in a component to talk to itself.
Performance wise, this pattern will always beat events.Peace, MikeOn 8/23/06, tddclare [EMAIL PROTECTED]

 I'm creating a custom component extending UIComponent.

   the size of it
   manually (example: the height and width are 150, and they create a

   My commitProps and updateDispList are VERY conditional - only redrawing
   the elements that

   What I can't find / missed is how to know the component itself resized

   is that event / how
   do I tell they resized me?

RE: [flexcoders] Re: Remote object help again..

2006-08-23 Thread Jeff Vroom













I have not heard of this caching bug
before, but Ill follow up and see Flex Builder is doing any caching that
might cause this. 



It is the case that when you compile your
SWF, the compiler needs to have a pointer to your services-config.xml
file. It includes a subset of the destination configuration into the SWF.
You can see what it has included when you enable debug logging on the
client (e.g. via: mx:TraceTarget/), or you can just trace it out via:



import mx.messaging.config.ServerConfig;



.



 trace(ServerConfig.xml);



When Ive seen this problem in the
past, it was due to the fact that the compilers configuration did not
include a pointer to the correct services-config.xml.

Did you add your destination after your Flex Builder
project was
created? We hear about this problem quite often. It appears Flex
Builder caches remoting-config.xml and does not fetch the file every
time you build the project. As a result, if a destination is added
after the project is created, it will not be recognized unless you do
one of the following:

- restart Flex Builder
- open project properties window, select the 'Flex Compiler' section
and click 'Apply'

It would be very helpful to get a confirmation from Adobe for this bug.

Thanks,
Mark

[flexcoders] FDS + Hibernate exception committing updates

2006-08-23 Thread Thunder Stumpges

Hi all,

I have loaded a collection of managed objects, made some changes to
one of them, and called the DataService.commit() to commit these
changes back to the database.

My DataService is connected to a HibernateAssembler destination, and
this destination worked to create the initial version of the objects,
however when I attempt to update them, I get this exception. I can
tell there was a data sync conflict (not sure why, I'm only using one
client, one session, one update to the object). However what concerns
me more is that  it's attempting to do something afterwards, and I get
this Hibernate exception about the session being closed. Any ideas?
thanks in advance,
Thunder

RE: [flexcoders] Similar Node Access Question

Hey, answered my own quetion... figured I'd post it here in case it helped 
anyone else...

So... you're using an mx:WebService to call a ColdFusion CFC.  The 
ColdFusion query object returned in lastResult is an array inside an array, 
but, it's more than that too (the debugger is your friend) so... the easiest 
way to grab a specific value from specific row in a query is to refer to the 
query row by array notation and the column by name... so... to grab the 
FULLNAME column from row 1 of your query object's result set you'd use...

var mystr : String = MyWebService.myOperation.lastResult[0].FULLNAME;

and if you wanted to bind to that purely in mxml you could also use...

mx:ArrayCollection id=ac source=MyWebService.myOperation.lastResult /
mx:TextArea text={ac.getItemAt(0).FULLNAME} /

Date: Wed, 23 Aug 2006 13:54:19 -0400

Don't know if this is the same problem as my recent, previous post, or if
it's different, but I basically have the same question...

Now I'm calling a CF WebService that returns a Query object... it just
contains one row, one column, called FULLNAME.

Using the WebService lastResult in a DataGrid's dataprovider works fine,
there's a million examples of that, but trying to pull out that FULLNAME
cell's string value is proving to be a challenge for me...

?xml version=1.0 encoding=utf-8?
mx:Application
 xmlns:mx=http://www.adobe.com/2006/mxml;
 creationComplete=IACleanService.authenticateUser.send()

 mx:WebService id=IACleanService
wsdl=http://localhost/ia_cleanup.cfc?wsdl;
 mx:operation name=authenticateUser
 mx:request xmlns=
 usernamejsmith/username
 passwordasdf1234/password
 /mx:request
 /mx:operation
 /mx:WebService

 mx:DataGrid height=400 width=400
 dataProvider={IACleanService.authenticateUser.lastResult} /

 mx:TextArea width=400 height=400
 text={IACleanService.authenticateUser.lastResult.fullname} /

/mx:Application

The DataGrid above displays the FULLNAME field just fine, but the TextArea
displays nothing.  Doesn't help to uppercase it to lastResult.FULLNAME
either.

I'm probably missing something really simple, but... just about all the
examples in the Flex documentation either show how to pull out a single 
node
value from an HTTPService... or show how to use a WebService in a
DataGrid... but I can't find any examples where single values are pulled 
out
of a WebService result.  Something where the result node values are split 
up
and used in different places, like one node value is used as a role
variable, another is used to set a model state variable, another is used as
a button label, etc.  I need an example of calling a WebService and 
breaking
the result into pieces for use in multiple places, not just sticking the
whole lastResult into the dreaded DataGrid.  Any help would be appreciated
:-)

Thanks!
Darren

Yes, use a server-side proxy to return the

Though to be honest, I am not absolutely certain
that this data is not cached somehow.

RE: [flexcoders] How to cast a WebService lastResult when CFC returnType=xml

2006-08-23 Thread Tracy Spratt













Darren,

You are using a tree according to the
example in  your post.  Or have you changed your question?



At any rate, binding is very difficult to
debug.  I advise using a handler function in which you can use toXMLString() on
the event.result object.



Then work your way down through the
hierarchy a step at a time.



When you get the _expression_ that works you
can put it in the binding _expression_.

Peter,

Thanks! But I'm not using the results in a Tree or Grid, which seem to have 
some magical parsing happening inside for you. I just want to do something 
as simple as pulling a node value out of the incoming SOAP wrapped XML and 
using it in, say, a TextArea. But... the following doesn't work...

mx:TextArea 
text={MyService.myOperation.lastResult.people.person.firstname}
/

nor does

MyService.myOperation.lastResult.people.person[0].firstname
MyService.myOperation.lastResult.person.firstname
MyService.myOperation.lastResult.person[0].firstname

or any other pattern I've tried. Amy suggested referencing the path all the 
way from the root node of the SOAP packet itself and treating the entire 
SOAP message as a bix XML result, instead of just the node path of the 
result. Something like...

MyService.myOperation.lastResult.myOperationResult.people.person.firstname

but I couldn't get that to work either.

Darren,

If your XML nodes have attributes (ie. node label=foo/node)
- you
can use the 'labelField' attribute to control the labels.

 mx:Tree id=myTree labelField=@label/

If they don't (ie. foobar/foo) - or if you want to do
any sort of
custom label logic, you need to use the 'labelFunction' attribute to set
the values appropriately.

mx:Tree id=myTree2 labelFunction=myLabelFunc/

 public function myLabelFunc (item:XML):String{

 //if node has children

 if(item.children().toString() !=
''){

 return item.name();

 }

 //no children, it's a leaf so get
the value

 else{

 return
item.toXMLString();

 }

 }

 ArrayUtil.toArray(TestService.getEmployee.lastResult)
 
 Is there something I need to do to the lastResult to get it to work in

RE: [flexcoders] Project References vs. ActionScript Build Path

2006-08-23 Thread Daniel Thompson

Thanks Martin; this is good information. It sounds like the JDT has a good
solution, although I wouldn't mind seeing behavior similar to Visual Studio
where referenced projects are built and then added to the bin directory of the
referencing project. I recently read a thread here talking about how to handle
multiple swf/swc projects and I hope to see further discussion on these topics
in the future.

Thanks again for your insight,

 This was something i've been wondering about so I double checked the behaviour
 of the JDT and search the help and it says this :
 
 'The referenced project list is used to determine the build order. A project
 is
 always built after all its referenced projects are built.'
 
 BUT, adding a project to the referenced project list doesnt automatically add
 it
 to the build path.
 
 For a Java project there is a tab on the 'Java Build Path' for 'Referenced
 Projects' which does add them to the build path..
 
 What I do miss from the JDT is exactly that, a referenced projects tab on the
 Flex Build Path (also adding multiple source folders for a single project
 would
 be nice..)
 
 The current 'browse the whole filesystem' feels a bit clumsy in comparison...
 
 but the JDT has had a long time to get to where it is..hopefully flex builder
 will soon incorporate those good features.

[flexcoders] Re: Cairngorm 2 - Web Service event handlers

2006-08-23 Thread ben.clinkinbeard

I've been using this method ever since I started with Cairngorm.
http://www.darronschall.com/weblog/archives/000234.cfm

It makes a lot of sense and just feels more natural to me to have the
commands handle the results and faults since they are the ones
requesting the calls anyway.

 I have a cairngorm 2 app that uses multiple delegates to call 
 different methods of a single web service.  The problem is, each 
 delegate adds it's own onResult and onFault events, so that when 
 the web service operation is called, *ALL* of the onResult functions 
 are called instead of just the one associated with the calling 
 delegate.
 
 For example, one delegate has the following code:
 
 this.service = ServiceLocator.getInstance().getService
 (sym_security_standard) as WebService;
 
 service.addEventListener(ResultEvent.RESULT, 
 sym_security_sp_login_search_onResult);
 
 service.addEventListener(FaultEvent.FAULT, 
 sym_security_sp_login_search_onFault);
 
 
 Another delegate has the following (similar) code:
 
 this.service = ServiceLocator.getInstance().getService
 (sym_security_standard) as WebService;
 
 service.addEventListener(ResultEvent.RESULT, 
 sym_security_sp_group_search_onResult);
 
 service.addEventListener(FaultEvent.FAULT, 
 sym_security_sp_group_search_onFault);
 
 
 
 Since there's only one instance of the ServiceLocator, each delegate 
 is registering onResult / onFault events to the *same* object 
 instance, and therefore the onResult event triggers the onResult

 Any ideas on how to avoid this?

RE: [flexcoders] FDS + Hibernate exception committing updates

2006-08-23 Thread Jeff Vroom













Are you using either the version
or timestamp features of hibernate? This causes improper
conflicts to be detected in the GMC version (though we have fixed this already
in house). To workaround that problem, you can turn off conflict detection:




update-conflict-modeNONE/update-conflict-mode



in your destinations server
tag. If that is not a suitable workaround, let me know. We
distribute the HibernateAssembler source so I could send you a version with the
fix in it.



I may also see the problem with the lazy
initialization exception there is code in the hibernate assembler which
goes through and does a deep fetch of all properties which are
not lazy=true associations in FDSs configuration. Hibernate
by default has all of its properties marked with its own setting of lazy=true
which means that those properties are not fetched when the parent object is
fetched. Since we need to serialize the state of all non-lazy properties
and do not want to keep the hibernate session open for this process, we do this
deep fetch ahead of time to be sure the state will be available for sending to
the client. Unfortunately, when we are throwing a DataSyncException for
the conflict we are not doing the fetch of the object properties for the serverVersion
of the object which also gets sent back to the client. If my theory is
correct, this error will go away when the conflict goes away but of course it
still needs to be fixed. I just made this fix locally so I could
send that along as well.

Hi all,

I have loaded a collection of managed objects, made some changes to

changes back to the database.

My DataService is connected to a HibernateAssembler destination, and
this destination worked to create the initial version of the objects,
however when I attempt to update them, I get this exception. I can
tell there was a data sync conflict (not sure why, I'm only using one

[flexcoders] Need help identifying which Event to listen for

2006-08-23 Thread Mike Anderson

Hello All,

I have a ViewStack Container, with many Children within.

Each child has it's own unique set of data-driven controls, and each
time the user goes back to a specific Child, I need to Requery the
database, so that I get the freshest data each time.  The easiest way to
do this, is listen for the Event for when a Child gets toggled.

I tried activate but this event kicks off only the FIRST time a
Container gets shown.  I need this even to kick off each and every time,
the ViewStack's Children get toggled.

Could any of you point out which event I need to trigger, in order to
for this to happen?

Thanks in advance,

Mike

Re: [flexcoders] Need help identifying which Event to listen for

2006-08-23 Thread Jeremy Lu

When selection changes, you can access current selected child via ViewStack.selectedChild, which points to the currently selected child container, you can then trigger a method inside the child to re-grab the data. see if this works for you :-)

Hello All,

I have a ViewStack Container, with many Children within.

Each child has it's own unique set of data-driven controls, and each
time the user goes back to a specific Child, I need to Requery the
database, so that I get the freshest data each time. The easiest way to
do this, is listen for the Event for when a Child gets toggled.

I tried activate but this event kicks off only the FIRST time a
Container gets shown. I need this even to kick off each and every time,
the ViewStack's Children get toggled.

Could any of you point out which event I need to trigger, in order to
for this to happen?

Thanks in advance,

Mike

[flexcoders] Re: FDS + Hibernate exception committing updates

2006-08-23 Thread thunderstumpgesatwork

Hi Jeff,

I am not using the version or timestamp features of hibernate, however
I am using the cascade=all feature to manage sets of child objects
off of the main managed object. In fact, it is this collection of
child objects that has changed (removed one, added one, etc.)

Should the transitive persistence work correctly using cascade=all
? Could this be part of the cause of the conflict?

Also, setting update-conflict-modeNONE/update-conflict-mode has
fixed the conflict issue, and with it the closed session exception.

If you were to send me those fixes, how difficult would it be for me
to encorporate them into my version of FDS? Do I need to build the
entire project? I have not done so before, but if needed, and I should
have all the source necessary, I'm comfortable attempting it.

thanks,
Thunder

 This causes improper conflicts to be detected in the GMC version (though
 we have fixed this already in house).  To workaround that problem, you
 can turn off conflict detection:
 
  
 
 update-conflict-modeNONE/update-conflict-mode
 
  
 
 in your destination's server tag.   If that is not a suitable
 workaround, let me know.   We distribute the HibernateAssembler source
 so I could send you a version with the fix in it.
 
  
 
 I may also see the problem with the lazy initialization exception...
 there is code in the hibernate assembler which goes through and does a
 deep fetch of all properties which are not lazy=true associations in
 FDS's configuration.  Hibernate by default has all of its properties
 marked with its own setting of lazy=true which means that those
 properties are not fetched when the parent object is fetched.  Since we
 need to serialize the state of all non-lazy properties and do not want
 to keep the hibernate session open for this process, we do this deep
 fetch ahead of time to be sure the state will be available for sending
 to the client.  Unfortunately, when we are throwing a DataSyncException
 for the conflict we are not doing the fetch of the object properties for
 the serverVersion of the object which also gets sent back to the
 client.  If my theory is correct, this error will go away when the
 conflict goes away but of course it still needs to be fixed.   I just
 made this fix locally so I could send that along as well.

 Subject: [flexcoders] FDS + Hibernate exception committing updates
 
  
 
 Hi all,
 
 I have loaded a collection of managed objects, made some changes to
 one of them, and called the DataService.commit() to commit these
 changes back to the database.
 
 My DataService is connected to a HibernateAssembler destination, and
 this destination worked to create the initial version of the objects,
 however when I attempt to update them, I get this exception. I can
 tell there was a data sync conflict (not sure why, I'm only using one
 client, one session, one update to the object). However what concerns
 me more is that it's attempting to do something afterwards, and I get
 this Hibernate exception about the session being closed. Any ideas?
 thanks in advance,
 Thunder

True, but then you're relying on server side sessions... that's stateless, 
but not independant of the back-end technology.

Flex inherits the HTTP session that the page which contained the EMBED

yet we can easily secure those.  The theory is identical with Flex.

  Hi Barry,

  I'm not sure if I can be of much help here. I'm not into PHP, I'm
not into
  FDS and remoting and the AMF protocol that is related to it. For
me, but
  that is totally a personal opinion, the only acceptable solution for
  communication with a back-end is webservices, and nothing else.
Briefly
  here
  are my reasons:

  *  The coolest thing about Flex is not the graphics ... but that you
  can make your server stateless, meaning that you obtain 100% fail-over
  characteristics including linear scalability. With FDS (or any other
  related
  solution) you highly likely lose this `feature' and my guess is that
  scalability will be tougher to achieve; for sure it is harder to
guarantee
  ... with a stateless server solution you can. And we always want to
grow
  with our applications, don't we???
  *  I like to keep my Flex layer totally independent of my back-end
  layer. My back-end layer should not be aware by any means of the client
  technology. With webservices you realize this. With FDS (or any other
  related solution) you get a vendor lock-in, which I consider
undesirable.
  *  The trend in my business is that more and more you get projects only
  for a front-end or back-end solution. In the past it occurred more
that you
  had to build them together, but that is changing. It's very
acceptable to
  request a back-end to expose its operations through webservices.
It's not
  very accetable to request them to expose it via FDS or something
like that.

  To be fair, there are some disadvantages using web services as
well; among
  others:

  *  No automatic conversion of the web service results into your custom
  action script classes. You have to make converters yourself to
accomplish
  this. With FDS/AMF I understand you can have this conversion
automatically
  done for you.
  *  Performance. People tend to say that webservices are slow. It's true
  that the serialization/deserialization of the XML (both on client and
  server) side takes computing time. My experiences so far are that this
  extra
  computing time is not causing any serious damage in the user
experience.
  *  Flex has some trouble communicating with DOC/Literal encoded
  webservices. Especially in the .Net corner this is causing
problems. But
  that should be temporarily ... The adobe guys are working on it and
  hopefully in a next release these issues will be fixed.

  For me the advantages of webservices by far outweigh the
disadvantages. So
  if you ask me: use webservices! You keep your freedom ...

  Cheers,

  Franck

RE: [flexcoders] Variable Type for Web Service Result

Ethan,

I don't think it's your typing, I think it's your timing.  Looks like you're 
flipping your postTyper() when the combobox is changed, but that's not 
firing a new send() like the original blogger example did.  Try changing 
your code so that changing the combobox triggers the send() and the send 
result= handler triggers the postTyper().  That way you'll have the 
correct data in lastResult when you change your blogResult variable.  That 
change should then be noticed by the bindings.

Subject: [flexcoders] Variable Type for Web Service Result
Date: Wed, 23 Aug 2006 16:13:19 -0700

Greetings -

Expanding on the Connecting to Web Services tutorial, I added a
combo box for switching between methods of the API to the Adobe blog
aggregator, ie from getMostPopularPosts to search.

As both methods return the same columns, the data grid displaying the
result can stay the same, other than needing a different value for
data provider, ie:

   myWebService.getMostPopularPosts.lastResult
vs
   myWebService.search.lastResult

I was hoping therefore to bind the dataGrid dataProvider value to a
variable which I'd set when users change the value of the comboBox
(which selects which method to use). However I think I'm typing the
variable which stores the value of the service result wrong, as I get
null whenever I try and set the value (blogResult), show below:

Darren,

You are using a tree according to the example in  your post.  Or have you 
changed your question?



At any rate, binding is very difficult to debug.  I advise using a handler 
function in which you can use toXMLString() on the event.result object.



Then work your way down through the hierarchy a step at a time.



When you get the expression that works you can put it in the binding 
expression.

Peter,

Thanks! But I'm not using the results in a Tree or Grid, which seem to have
some magical parsing happening inside for you. I just want to do something
as simple as pulling a node value out of the incoming SOAP wrapped XML and
using it in, say, a TextArea. But... the following doesn't work...

mx:TextArea
text={MyService.myOperation.lastResult.people.person.firstname} /

nor does

MyService.myOperation.lastResult.people.person[0].firstname
MyService.myOperation.lastResult.person.firstname
MyService.myOperation.lastResult.person[0].firstname

or any other pattern I've tried. Amy suggested referencing the path all the
way from the root node of the SOAP packet itself and treating the entire
SOAP message as a bix XML result, instead of just the node path of the
result. Something like...

MyService.myOperation.lastResult.myOperationResult.people.person.firstname

but I couldn't get that to work either.

 Darren,
 
 If your XML nodes have attributes (ie. node label=foo/node) - you
 can use the 'labelField' attribute to control the labels.
 
  mx:Tree id=myTree labelField=@label/
 
 If they don't (ie. foobar/foo) - or if you want to do any sort of
 custom label logic, you need to use the 'labelFunction' attribute to set
 the values appropriately.
 
 mx:Tree id=myTree2 labelFunction=myLabelFunc/
 
  public function myLabelFunc (item:XML):String{
 
  //if node has children
 
  if(item.children().toString() !=

[flexcoders] AS HTTPService ignoring method propety

2006-08-23 Thread James Polanco

Hey all, 
I am using the ActionScript HTTPService and I found an issue with it.
I  feel its a bug, but I may have been misusing the functionality
and I got away with it until I pushed too far.  Here is the problem/issue:

I have a JSP app that I am calling via HTTP that returns XML data. 
One of the services requires that the data comes in via POST and not
GET.  No biggie, just set the method propert... or so I thought.

When I called the app it kept coming back with  and after looking at
the HTTP headers we realized it was always coming in as a GET even
though I explicitly set it to POST.  This is where things started to
get odd... some of my service calls (all routed through the same
service code) came out as POSTs and some as GETs.

I was able to track down the cause and it was all based around the
format of the object that I was passing to the request property.  For
example, if I did it this way my call became a POST (as desired)

myService.request = {zip: 94103};


If I created a custom VO class that had public properties that matched
the required parameters it converts to GET on the call(protocode):

class MyZipVO
{
 public var zip:String = 94103;
}



var temp:MyZipVO = new MyZipVO();
myService.request = temp;

I didn't catch this at first because my previous services worked as
either GET or POST but once I tried to access the one that required
POST it all blew up.  Anyway, I figured it out and I can work around
it, but any idea on why this fails or if this should work in the first
place?

James

[flexcoders] Re: Adobe, Help Memory Leaking !!

2006-08-23 Thread Henry

Yes I have had the same problem with all the applications that I have
created.  Not sure if bad coding on my part or bug in the plugin. 
Hope this problem gets fixed soon!

[flexcoders] Tree Datagrid highlight color bug?

2006-08-23 Thread Jeff Kroll






Hi 
All,
I developed an 
application that's essentially a property sheet with a tree and dataGrid in it 
and it works just fine. Specifically, when I roll over a tree item or row in the 
dataGrid , color of the background automatically changes to the nice default 
"highlight" blue.

Later I decide I 
want to have this property sheet application pop up by clicking on a button in a 
launcher app, so I build the launcher appand change the property sheet 
application so it can be launched (replace Application with titleWindow, etc... 
very easy).

Now when I launch 
the property sheet, the background color of the selected and rolled over tree 
items and dataGrid rows are black, and the text color is super dark 
gray!!!

What gives? Is this 
a known bug and is there a work around?

By the way, I'm not 
using any Style sheet or Style declarations. It's all very vanilla code, and 
everything else about the popped up property sheet works as before. It's just 
the highlight color that's wonky.

Cheers,Jeff

Re: [flexcoders] Adobe, Help Memory Leaking !!

2006-08-23 Thread Joshua Garnett




Have you tried setting the recycleChildren attribute of the Repeater to false? I believe when you have recycleChildren set to true, even if you reduce the number of items in the dataProvider, it still keeps an object in memory that it will reuse. I've actually encountered other issues with having recycleChildren set to true when the repeaters are nested within repeaters. There doesn't seem to be any noticeable performance hit by switching it to false.

When the GC runs it destroys objects within the
totalMemory within the player. When the player needs more memory for new
objects, it adds memory if the gc cannot dispose of what is needed. It is true
to say that on machines with ample resources, the player may accumulate more
resources but this is true with all applications.



I have to say I think you may be looking at a bug specific
to your os/system configuration. Is the behavior browser specific?

I first noticed this issue while looking at the task

browser use less memory? Is that what you are saying?

Ok
got some information for you:



flash.system.System.totalMemory
- The amount of memory (in bytes) currently in use by Adobe
Flash Player.



A
better way to think about this is allocated memory. When the player needs more
memory it acquires it from the OS/Browser in use. The player doesn't
necessarily give the memory back. Within that memory in use are the objects
being used. When GC runs, it disposes objects within the allocated memory but
doesn't give memory back to the OS/Browser.



The
GC is running and collecting objects, but f lash.system.System.totalMemory
is not the right way to see this happening.

This is a huge probolem on my app because it has like 30 Repeaters that are

   Hi Barry,
   
   
   
   I'm not sure if I can be of much help here. I'm not into PHP, I'm
 not into
   FDS and remoting and the AMF protocol that is related to it. For
 me, but
   that is totally a personal opinion, the only acceptable
solution for
   communication with a back-end is webservices, and nothing else.
 Briefly
   here
   are my reasons:
   
   *The coolest thing about Flex is not the graphics ... but that 
   you
   can make your server stateless, meaning that you obtain 100%
fail-over
   characteristics including linear scalability. With FDS (or any
other
   related
   solution) you highly likely lose this `feature' and my guess is
that
   scalability will be tougher to achieve; for sure it is harder to
 guarantee
   ... with a stateless server solution you can. And we always want to
 grow
   with our applications, don't we???
   *I like to keep my Flex layer totally independent of my back-end
   layer. My back-end layer should not be aware by any means of
the client
   technology. With webservices you realize this. With FDS (or any
other
   related solution) you get a vendor lock-in, which I consider
 undesirable.
   *The trend in my business is that more and more you get
projects only
   for a front-end or back-end solution. In the past it occurred more
 that you
   had to build them together, but that is changing. It's very
 acceptable to
   request a back-end to expose its operations through webservices.
 It's not
   very accetable to request them to expose it via FDS or something
 like that.
   
   
   
   To be fair, there are some disadvantages using web services as
 well; among
   others:
   
   *No automatic conversion of the web service results into your
custom
   action script classes. You have to make converters yourself to
 accomplish
   this. With FDS/AMF I understand you can have this conversion
 automatically
   done for you.
   *Performance. People tend to say that webservices are slow.
It's true
   that the serialization/deserialization of the XML (both on
client and
   server) side takes computing time. My experiences so far are
that this
   extra
   computing time is not causing any serious damage in the user
 experience.
   *Flex has some trouble communicating with DOC/Literal encoded
   webservices. Especially in the .Net corner this is causing
 problems. But
   that should be temporarily ... The adobe guys are working on it and
   hopefully in a next release these issues will be fixed.
   
   
   
   For me the advantages of webservices by far outweigh the
 disadvantages. So
   if you ask me: use webservices! You keep your freedom ...

Hey Jeff,

This is very helpful. I didn't know about the
trace(ServerConfig.xml) trick. Would it make sense to add some
special logic to the compiler to validate all destinations in the
code? That would need to apply to all mx:RemoteObject declarations as
well as ro.destination = xxx type of assignments.

Cheers,
Mark

 Flex Builder is doing any caching that might cause this.  
 
  
 
 It is the case that when you compile your SWF, the compiler needs to
 have a pointer to your services-config.xml file.  It includes a subset
 of the destination configuration into the SWF.  You can see what it has
 included when you enable debug logging on the client (e.g. via:
 mx:TraceTarget/), or you can just trace it out via:
 
  
 
 import mx.messaging.config.ServerConfig;
 
  
 
 
 
  
 
  trace(ServerConfig.xml);
 
  
 
 When I've seen this problem in the past, it was due to the fact that the
 compiler's configuration did not include a pointer to the correct
 services-config.xml.

 Did you add your destination after your Flex Builder project was
 created? We hear about this problem quite often. It appears Flex
 Builder caches remoting-config.xml and does not fetch the file every
 time you build the project. As a result, if a destination is added
 after the project is created, it will not be recognized unless you do
 one of the following:
 
 - restart Flex Builder
 - open project properties window, select the 'Flex Compiler' section
 and click 'Apply'
 
 It would be very helpful to get a confirmation from Adobe for this bug.

[flexcoders] Don't bindings work both ways??

2006-08-23 Thread Mike Anderson

Hello All,

I have a Form with several fields - and those fields are all bound to a
ValueObject (using the Curly Braces method).

After doing my database calls, etc., my Form populates beautifully with
all the values.  However, if I edit any of those fields on the Form, and
then send the same ValueObject back to the server, nothing is changed -
it's as if I didn't make any changes to the Form itself.

It was my understanding, that once a Binding Relationship is created,
that any changes (either in the Model itself, or the Fields that are
tied to the Model) will update in both directions.

Is this not true, or am I missing something?

Thanks all for your help,

Mike

Matt,

the filter is removing Items indeed, to solve the problem , I set the verticalScrollPosition
to 0 before applying the refresh() method. 
To have it assigned to a single dataProvider , it's not a problem to use this
kind of workaround but I think this should be handle by the listclass.

arrayCollection (using filterFunction) used inside a listbox. If the list is
positioned at the beginning everything works fine but if I scroll down on my
list and apply the refresh this error is thrown.



Any Ideas?



Thanks,

Hi All,
Actually m migrating my application from flex1.5 to flex 2 :
In Flex 1.5 the code was somewat like this:
generated\service\BulkCrudService.mxml(56): Warning: variable
'__call' 
has no type declaration.
var __call /*: PendingCall*/ ;
This variable we are using in service files,just to store how many 
pending calls are there.

In flex 2 ,this code is giving me a warning as now variable should 
have its type.
So as per the code in flex 1.5 the class mx.remoting.PendingCall; is 
nto there in flex 2 ,so what should i use instead of PendingCall class.

If anyone has any idea ,plz reply.

Yeah, RAD 6.0 is based on Eclipse 3.0.2, I
believe they are updating in their next release.  We will be working with them
to try to make things compatible.  So for now you do need two versions of

RE: [flexcoders] AS HTTPService ignoring method propety













Ah, I believe HTTPService does a for..in
loop over the parameters, and if you use a strongly typed class the for..in wont
return anything. Then when you try to send no parameters to a POST request it
will be turned into a GET by the Player.



We should make sure thats mentioned
in the docs (or look into changing that behavior).

Subject: [flexcoders] AS
HTTPService ignoring method propety











Hey all, 
I am using the ActionScript HTTPService and I found an issue with it.
I feel its a bug, but I may have been misusing the functionality
and I got away with it until I pushed too far. Here is the problem/issue:

I have a JSP app that I am calling via HTTP that returns XML data. 
One of the services requires that the data comes in via POST and not
GET. No biggie, just set the method propert... or so I thought.

When I called the app it kept coming back with  and after looking
at
the HTTP headers we realized it was always coming in as a GET even
though I explicitly set it to POST. This is where things started to
get odd... some of my service calls (all routed through the same
service code) came out as POSTs and some as GETs.

I was able to track down the cause and it was all based around the
format of the object that I was passing to the request property. For
example, if I did it this way my call became a POST (as desired)

myService.request = {zip: 94103};

If I created a custom VO class that had public properties that matched
the required parameters it converts to GET on the call(protocode):

class MyZipVO
{
public var zip:String = 94103;
}



var temp:MyZipVO = new MyZipVO();
myService.request = temp;

I didn't catch this at first because my previous services worked as
either GET or POST but once I tried to access the one that required
POST it all blew up. Anyway, I figured it out and I can work around
it, but any idea on why this fails or if this should work in the first
place?

James

 OK, so I've watching this thread going back and forth over and over...
 Now it's time for my two cents. It looks like this thread began by
 someone saying that you cannot use web services in a real world flex
 application. I've got to agree with Dave on this. You definitely can,
 and we have done it numerous times here at Cynergy. 
 
 
 
 Are there tradeoffs? Yes. As others have said already in the post:
 The decision on what mechanism to use should be dealt with on a case by
 case basis. Let's consider a few things:
 
 
 
 1. Do the web services already exist and can they handle the
 current load? If they do, use them. Why reinvent the wheel? 
 2. Yes, there is a performance advantage to using AMF, but most
 users will not notice the difference in transport speed... it is
 fractions of a second. If your application is properly architected and
 your backend is optimized, the end user will never know the difference.
 
 
 
 I personally like using remote objects, but not every solution allows
 for this. In the cases where you cannot use remote objects, web
 services still work great. SOAP is a very verbose protocol, but by no
 means is it unusable. If that were the case, why would web services be
 so prevalent? Why would there be all the buzz about service oriented
 architectures? 
 
 
 
 If you feel that a web service is too verbose or too slow, and you can't
 use remote objects, then use a HTTPService to return XML. There are
 many solutions. It really all boils down to how you use and retrieve
 your data and depends on your requirements and application architecture.
 If the processing time on the server is too much for your application to
 handle, then chances are there is a problem with your application's
back
 end, not the webservice/serialization layer. 
 
 
 
 To generalize and say that you should never use a web service is a very
 big mistake.

 OK . . . . so the lag time is when the data gets back to the end-user?
 
 
 
 Bottom line . . . . with all things being equal . . . .
 
 
 
 Does a web service request take longer to process on the server than
 
 a AMF request?
 
 
 
 If the answer is . . . . in general yes, then that can be an issue with
 an
 
 increase in users.
 
 
 
 If the answer is . . . . it depends on the data being requested and/or
 the

 compare results and then test again based on scaling up.

Hello
All,

I have a Form with several fields - and those fields are all bound to a
ValueObject (using the Curly Braces method).

After doing my database calls, etc., my Form populates beautifully with
all the values. However, if I edit any of those fields on the Form, and
then send the same ValueObject back to the server, nothing is changed -
it's as if I didn't make any changes to the Form itself.

It was my understanding, that once a Binding Relationship is created,
that any changes (either in the Model itself, or the Fields that are
tied to the Model) will update in both directions.

Is this not true, or am I missing something?

Thanks all for your help,

Mike

2006-08-23 Thread Franck de Bruijn













Hi Ted,



We all understand your arguments 1 and 2.
But in the end, and thats already identified in this topic, its
the user experience that counts. If it does not suffer by using web services,
its not an issue! Id like to hear the first story that changing
webservices by AMF increased the user experience significantly and sealed a
certain business proposition.



For argument 3 Developer
Productivity its true that developers need to program more lines
of code to obtain the same result (having your webservice result as an
ActionScript object), which is, I admit, error prone. But in the total view of
the costs of a development project ... it will not make much of a difference.
The actual additional lines of code Im talking about, however, are very
easy to generate from a model if you wish.



Again, FDS is cool, really true and it
does have its place. But for many applications FDS (including the extra
features messaging and data management) is neither an option nor necessary.



Cheers,

Franck

[flexcoders] Re: Choice of backend systems - which provides













AMF is
faster in 3 fundamental ways:




 Bandwidth Size  Smaller, lighter,
 faster!!!





 Parsing Speed  Less work on both client
 and server!!!





 Developer Productivity  Less work for
 developers!!!




Web Services
are dependent on XML Parsing on both the client and server side. Although
its a good story, XML parsers are not very efficient as parsing
documents is an interpreted process. The Flash Player XML parser will always be
dramatically slower than AMF parsing, binary formats are notoriously faster in
this regard. 



XML
parsing additionally decays rapidly as the file size increases. Flash Player
XML parsing time increase non-linearly with larger XML documents. With AMF
parsing times are linear with data size. The XML decay can be attributed to the
number of inner objects that need to be created during a parsing run. AMF
objects are 1:1 with the data received where XML data is 1:N per
Elements/Attribute.



Comparing
XML to AMF is an unfair race, AMF wins every time. When you add in the overhead
of WS SOAP parsing atop the base XML parser speed you begin to see performance
issues. With SOAP, you interpret an XML document back into typed objects
depending on the SOAP specifics used. Sure 350ms is ok once or twice, but try
doing 200 transactions in this format and you will see performance issues
arise. Using Web Services you are forcing the Flash Player to do allot of
unneeded work. The goal is to build richer applications, not burn up player
performance in crud operations.



Additionally
non-proxied Web Service use suffers with Flash Player because of the browser
variation in the plug-in APIS. You cannot get the 500 Errors response content in
IE and thus the SOAP fault standard breaks down. In SOAP there are important
messages that arrive with 500 Errors and the inability of the Flash Player to
receive these is a problem. Unfortunately there is no seamless way to get 500
Errors into the Flash Player other then rewriting an HTTP Client in the Socket
class. This effort would also require a new SOAP library within Flex and socket
use on low ports requires a more complex crossdomain.xml configuration.
Even then you still suffer the same performance issues.



Performance
aside, the productivity discussion is much more important. AMF3 and Flex Data
Services are wildly productive. Once you compile your Java Class and configure
a destination in FDS (1 XML Element), you are done. All typing is handled, All
methods are ready to run with any number of client applications. It is the
easiest way to create a server side API that I know of. Actually most cases,
implementing FDS will removes $20,000 of developer time wasted on implementing
other data exchange for an application. FDS value is easy to see when viewed
through this productivity ROI metric. If you add CF integration into FDS, you
enjoy an even more productive jump. We spend so much time talking about
performance but we often waste so much developer time doing mundane data
exchange when things could be automated.



Having
worked at Cynergy Systems, everyone needs to realize that Carson, Dave and Team
are industry leading professionals at Web Services. They know SOAP better than
any single consulting firm that I know of. These guys were on teams at Sybase
and Microsoft building the first generation of Web Services integration servers
(MS BizTalk, EAServer)!!! They have the expertise to make Web Services/JAVA
work seamlessly with Flex but this is out of reach for most (unless you hire
them). They can jump through flaming hoops that few developers can with the
FLEX / TOMCAT / AXIS / JAVA stack. They have been down a very hard road and
