Re: [flexcoders] Re: "undefined" in stack trace (Console), stack overflow (2nd try)

[Erik de Bruin]

Alex,

The local variables in methods "on the stack", by which I presume you
mean "have been called recently", are mostly counters and such, as
well as references to properties of other objects, to avoid too much
lookup (myVarRef instead of repeatedly calling
Controller.instance.myList.myVar).

2 questions:
- can I somehow increase the size of the stack for the AIR player on
MacOSX? (Google tells me "probably not", but I have to ask);
- where can I learn more about the "stack" and how to "debug" it, so I
can stop bothering you with these questions?

Thanks,

EdB

[flexcoders] Re: create class on the fly

[wrhinfl]

Ok, I think the way your question is worded can cause problems with the answer 
you get.

If your real question was "Can a class be modified during runtime and how?"  
Would this be the same question you are asking?

I searched the ASDocs and found Dynamic Class, which allows you to add 
variables and functions to an instance of a class.  I created a simple 
application and uses one AS class twice, creating different variables and 
functions in the two instances.

The project I am working on is trying to do something very similar where I 
don't want hundreds of classes to match the hundreds of tables (and would 
require hundreds of java classes on the server).  

And your question made me do some searching, so let me know if this question 
and answer are closer to what you are trying to accomplish in your project and 
I can share my simple code (two files with 70 lines of code, no comments).

[flexcoders] clearing the flex cache?

[jedierikb]

I would like to clear my cache of all the flex libraries used by my browsers.  
I would like to do this to see the speed of my flex apps loading the flex rsls 
for the first time.

Are there instructions for how to do clear my flex cache?  I tried deleting the 
files listed at the paths listed here 
http://livedocs.adobe.com/flex/3/html/help.html?content=rsl_09.html, but even 
when they are trashed (on windows vista), my flex app still seems to find the 
libraries somewhere  locally(I do not see the framework and rsl libraries 
download).  (side note: i am not linking the flex libraries into my own code... 
I am linking to them as rsls.)

[flexcoders] Linux says corrupt file when clicking on an air app.

[Raymond Brown]

Question for anyone who can point to a better answer than what google has 
currently provided:

 We wrote a adobe air app on OSX using the latest version of flex builder (3 
series) and the latest adobe air sdk.  When we export the air app and double 
click it on windows or OSX it installs fine and runs.  When we try the same on 
Linux we get an error message saying the file is corrupt and we need to contact 
ourselves (developers) for another copy.  I have tried this as root and general 
user on the linux system.  Any pointers is appreciated.

[flexcoders] LCDS without a class for every table?

[postwick]

OK, so I was the one looking for a way to do classes at runtime.  The bottom 
line is I want to use LCDS because it's, well, fantastic.  However, in my app I 
cannot know at compile time all the tables (and columns in them) that will need 
to be accessed.

Is there a way to use one single class which has a property on which I attach 
an object that contains the properties I need (probably in XML format) based on 
the table that should be updated, then modify the CFCs so that they extract the 
data, create/update/delete the correct table, and then pass the necessary 
information back to LCDS so that it pushes the update out to the clients?

On the datagrid side, instead of binding the grid to an ArrayCollection, I 
could bind it to a function that parses the XML property on the returned 
ArrayCollection and returns a new ArrayCollection (or populates a second one) 
with the correct data for the grid.

Does this sound reasonable and doable?  Is there any other way to use LCDS 
without having a class for every single table?

Thanks,
Paul

RE: [flexcoders] Re: "undefined" in stack trace (Console), stack overflow (2nd try)

[Alex Harui]

I'm not sure you can try/catch a stack overflow, and adding "try" does change 
the stackframe.  I think you're just running out of stack.  The stacks have 
different sizes on different platforms.  What kinds of local variables are in 
each method on the stack?

Alex,

Well, that's the thing. The code in that method doesn't seem to be the
problem. If I put the seemingly offending line in a try...catch block,
it runs without triggering the catch. And weirder still, the
"undefined" exception happens somewhere a little further in the
flow...

This happens only when I play the piece in AIR on a Mac. AIR on
windows doesn't show this problem and it also doesn't happen when the
code runs in the Flash plugin in a browser (on both platforms). Are
there any known issues that might relate to this?

Thanks again,

Re: [flexcoders] Re: create class on the fly

[Julien Nicoulaud]

Interesting topic !
I would like to go further on the dynamic class manipulations:
Does anybody see a way to list all classes from a package that implement a
given Interface ?
Well, the part "that implement a given Interface" is easy to do using
isPrototypeOf(), but the "list all classes from a package" part ?

I guess it is not possible, because "between" the two applications you
should have access to the system drag and drop manager. By the way, you can
do it in an air application.

Re: [flexcoders] Opening popups while in full-sceen mode would crash the browser

I noticed several bugs while trying to setup my application for full screen
mode:
 - Text fields not editable
 - keyboard events not dispatched
 - IFrame stay blank
 - ProgressBar crashing the browser (I guess this is the same issue as the

 - Drag and drop severe performance issues (My app uses flexlib's MDI
windows)

And this, on Flash Player 9 & 10, Linux and Windows.

[flexcoders] Programmaticly created Consumer does not find endpoint

[Michael Slinn]

I am able to programmatically create a RemoteObject to call RPCs
against, and now I am trying to programmatically create a messaging
Consumer that listens on a streaming AMF channel.

I have cranked up logging verbosity. I note the 404 (not found) message:
[SWF] /samples/testdrive-datapush/ProgMsg.swf - 883,736 bytes after
decompression
'my-streaming-amf' channel endpoint set to

'feed'.
'A9D9B478-E4BB-6C26-196F-7B082707F804' consumer subscribe.
'my-streaming-amf' pinging endpoint.
'my-streaming-amf' channel got status. (Object)#0
   code = "NetConnection.Call.Failed"

   details = "http://localhost:8400/samples/messagebroker/amfstreaming";
   level = "error"
'my-streaming-amf' channel polling stopped.

The streaming AMF endpoint looks right to me. What am I missing?

Here is the (small) test project source code:
http://www.mslinn.com/sites/flex/progMsg.zip

For convenience, the SWF and HTML files built by this test project drop
into the {BlazeDsTurnkey}/tomcat/webapps/samples/testdrive-datapush
directory and the project can be run from
http://localhost:8400/samples/testdrive-datapush/ProgMsg.html

[flexcoders] Custom Events in multiple components

[Jake Churchill]

I ran into something that I've never come across before and now curiosity is
killing me.  

 

I had a base component, call it ComponentBase.  I made this component
dispatch a custom event using the appropriate event metadata.  

 

I have another component which extends ComponentBase, call it SubComponent.
SubComponent gets used in mxml.  I want the event that I set up in
ComponentBase to be available in mxml the same as if I had added it to
SubComponent.  Does that make sense?

 

How do I get a custom event from a base component to come through to it's
children components?

 

Thanks!

[flexcoders] Setting firstVisibleItem in ADG

[vin.flex]

HI,


   I have an ADG with piechart as he itemrenderer for the entire row. 
If I click any node the chart is shown. 

  I want to set the opened node as the firstVisibleItem, so that 
the chart is visible completely. I am doing the following in itemOpen event.

myADG.fisrtVisibleItem = evt.item; 

This is not working everytime. Can anybody give sugggestions or other way to 
achieve this functionality.


thanks

Here's another way.  You would have some challenges with data tips, but

[flexcoders] Re: Remote AMF all in IE7 Fails NetConnection.Call.Failed: HTTP: Status 403

[valdhor]

403 is a "Access Denied/Forbidden" error. Seeing as you are making a secure 
call, could it be a damaged certificate file in IE? You may want to try 
repairing IE7 (http://support.microsoft.com/kb/318378) or perhaps some registry 
error?

[flexcoders] Remote AMF all in IE7 Fails NetConnection.Call.Failed: HTTP: Status 403

[Anthony DeBonis]

Need a fix for this ASAP - any help would be great

We have remote object calls to LCDS that work fine in Firefox and Chrome but 
fail when we user IE 7 as the browser.

FaultDetail: NetConnection.Call.Failed: HTTP: Status 403


Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 403: url: 
'https://{servernamehere}/doh2/applinks/webserv/datavis/messagebroker/amf'

IF I just hit the URL for the endpoint in IE7 it works fine - we get back a 
blank white empty page so we know the endpoint us available.

The Channel is using mx.messaging.channels.SecureAMFChannel 

service-config.xml entries:


http://{server.name}:{server.port}/{context.root}/messagebroker/amf"; 
class="flex.messaging.endpoints.AMFEndpoint"/>

   false




https://{server.name}:{server.port}/{context.root}/messagebroker/amfsecure";
 class="flex.messaging.endpoints.SecureAMFEndpoint"/>

false

[flexcoders] Re: remote sandbox addCallback

[Nicholas Bilyk]

I've narrowed the problem down further.

The Security.allowDomain("*") does allow this to work in flash.  In Flex, my 
problems are coming from the BrowserHistory javascript, that doesn't wait until 
the point where the Security.allowDomain call is made, causing a js error.

[flexcoders]

Hi coders, I have installed the flex 4 sdk (placed onto the sdk  
folder on flex builder 3)

let me know if I'm doing something possible or not.

[flexcoders] remote sandbox addCallback

[Nicholas Bilyk]

I have a swf that I'm trying to embed across sites. 

In the simplest form of the problem, I have the actionscript:

ExternalInterface.addCallback('foo', test);
function test():void {
// Do stuff
}

When the swf is embedded on the page in the same domain, the callback works.  
If the swf is loaded from a remote domain, the callback fails.  
I have allowScriptAccess="always", that allows the swf to call javascript, but 
not the javascript to call methods on the swf.

I have tried:
crossdomain policy
Security.allowDomain("*");

I just can't find the magic to make this work...
Any help will be greatly appreciated.

[flexcoders] Annotating a PieChart

[tphipps]

Has anyone played with the PolarDataCanvas canvas object to annotate Pie 
Charts? There are plenty of examples in the Live Docs and elsewhere on the web 
on how to annotate Bar and Column Charts (using a CartesianDataCanvas), but 
none that I can find using PieCharts.

Assuming that a valid NameField assigned to the chart's PieSeries is "Yellow", 
is it as simple as the following code?

var columnLabel:Label = new Label();
columnLabel.setStyle("fontWeight", "bold");
columnLabel.setStyle("color", "0x66");
columnLabel.text = "Hello"
annotationCanvas.addDataChild(columnLabel,'Yellow');

When called, this causes the chart to re-draw, but nothing appears inside the 
"Yellow" wedge.

I know that I could use labelPosition="inside" to accomplish something similar, 
but I already have callout labels and need an inner label in addition.

Thanks!

[flexcoders] Livecycle DS with Flex Questions

[Wally Kolcz]

I am trying to get into using LiveCycle DS with my Flex app. I have a couple 
question for anyone who uses it and understands it.

1.) If I were to have 2 seperate applications (swfs, client / admin) that both 
subscribe to the same destination, when a change is made (say a admin adds a 
records) would the client be notified of the change or doe it all have to be a 
single application? My site has 2 Flex application in different folders. I 
would like the changes to be reflected on the public's application if the 
admins make a change.

2.) I have used RemoteObject extensively with my CFC's to push data to my 
application. Does DataService replace RemoteObject by connecting to my CFCs and 
using them to connect to my SQL server?

3.) Does anyone know a good tutorial on how to create a destination in the  
data-management-config.xml file to point to a CFC?

Thanks!

[flexcoders] Re: Possible to create a chart with clustered & overlaid columns? (picture inside)

[EddieBerman]

While I haven't yet attempted that layout, here are my thoughts on one
potential path:

You'll need 5 series, with the first one (series 0) being the composite
(as the series are drawn from 0 to n, and if the composite column was
the last one it would draw over the previous columns).

You'll need to adjust the individual series columnWidthRatios and
offsets so that series 0 and series 1 start at the same x position, and
(obviously) series 1-4 take up the space of 5 series columns.

You'll need to have an itemRenderer for series 0. Override
updateDisplayList() and set the unscaledWidth to be wide enough to span
series 1-4.

Here are some potentially helpful links:
1) demonstrates tampering with columnWidthRatio and offsets:
http://www.stretchmedia.ca/code_examples/offset_calculator/SeriesOffsetC\
alculator.html


2) QuietlyScheming shows an example of complex stacking which you'll
need since series 0 is a composite:
  http://demo.quietlyscheming.com/ChartSampler/app.html


That's only a start as you'll still need to also create a custom legend
and deal with the challenge of having the first 4 clusters blue-ish and
the next 4 orange-y.  Having custom itemRenderers should help with that
coloring issue.

Good luck!

[flexcoders] using as an xaxis label on a bar chart

Hi, I have a string '' and I need to have the entire

Is there any way I can have this entire string displayed? 

[flexcoders] Re: create class on the fly

[ag_rcuren]

To return a class is pretty simple. If you look at the source of the Modules 
they have create method. For my example they are returning instances but there 
is no reason you can not return a Class from these, infact I have done it 
before so I know it works.

import mystuff.junk.SomeClass;
import mystuff.junk.AnotherClass;

public function create(type:String):*
{
switch (type)
{
case "SomeClass":
return SomeClass
case "AnotherClass":
return AnotherClass
break;
default:
break;
}
return null;
}

This will give you back a Class which you can then use as expected. 

Looking at it now I should have used a different name other than 
createdInstance for the getter in DynamicFactory because it really does not 
have to be an instance of something it can be any type.

Re: [flexcoders] Re: create class on the fly

[mark . jonkman]

Hi 

Somewhere you will need to write an .as file and compile it into a swf in order 
to use it at runtime. Flash can't compile an .as file or a string at runtime. 

You can however, compile any number of .as files into a Flex Library project, 
load that library at runtime then using getDefinitionByName retrieve the class 
reference then instantiate it. 

One way I do this in a semi automated way is as follows: 

Create a series of Flex Library projects in Flex Builder or Flash Builder. 
Create the appropriate classes in each of the library projects. 
Create one Flex project and name it something like Library_Builder. 
Link all the Flex Library projects against it as RSLs 
Set each RSL to auto-extract and give it a directory and filename to 
autoextract into. 
Then I compile that one project to recompile all my libraries and when I need 
the runtime (vs. debug versions) I just do a release build. 

I never post the Library_Builder project to my site, it has no code in it, it 
simply serves to build the debug and release versions of my libraries en-masse 
without having to do a lot of jumping through hoops. I actually configure the 
Library_Builder to build itself into the debug folder of my real project and 
the release into the release folder of my real project. I just skip posting it 
and even if it gets posted by accident, its totally useless. One could link a 
folder in Flex Builder from one project to another, but I like to check my 
folders into SVN and it gets checked out to the server so its easier to do it 
into my main project. 

You can have as many library projects as you want to break things into 
"modular" libraries to load on demand at runtime into your main project. To 
have a lot of one class library projects would be rather a nightmare to deal 
with, but grouping classes that are used together into the same library project 
is often wiser and less prone to dependency errors. Dependeny errors result if 
your library project needs access to classes in another library and that 
library is linked to as an external library during compile. Then you need to 
make sure the dependencies are resolved by having all necesary libraries 
loaded. I tend to use only a handful of very distinct libraries like this where 
all the dependencies are pretty much resolved internally or can be resolved by 
loading a single common library upfront first. 

I don't have access to the full thread right now so I'm not sure exactly what 
you are doing. But in order to access a class you need a compiled version of 
the class - aka in a swf somewhere. And you need to know the name of the class 
(fully qualified). You need to load the swf at runtime then access the class. 

Sincerely 
Mark R. Jonkman

Does this mean I don't have to create the class as a .as file and compile it 
into the SWF, I can just reference it this way? Then I could add a new class to 
myPackage and tell my app (via db, XML, etc) that there is a new class there to 
load? 

The point to all of this is a dynamic application where an end user can add 
their own tables, and I need classes for those objects so that I can pass them 
back and forth with data messaging.

[flexcoders] Re: create class on the fly

[postwick]

Thanks for everyone's help.  I think this points me in the right direction.

Of course, if there's a way to successfully use data messaging without 
instantiating classes...that would eliminate my need to do this.  But I don't 
think there is...

[flexcoders] Re: create class on the fly

[ag_rcuren]

Yes you could create the class and build it into an RSL. Once the RSL is loaded 
you can just reference it by name. When you add or make changes you just need 
to rebuild the RSL or push a new RSL out and have a way for your app to know 
whats available.

I found it easier to use Modules, because they are easier to build. I have 
examples of both RSL and Modules on that blog both have source enabled so you 
can take a look.

I have an app that lets users pick and choose "widgets" they want and I load 
only the components they want into the app via a config file. When ever I want 
to add new components I just publish a new module and update my database so my 
apps knows about it.

Re: [flexcoders] Re: create class on the fly

[mark . jonkman]

Hi 

If you load a module that has a pile of classes in it, you can instantiate them 
without having a static reference in your original code. However, you do need 
to be a bit cautious. 

By default, modules load into a child of Application.currentDomain and thus 
aren't as "accessible" as classes loaded directly into 
ApplicationDomain.currentDomain. 

If you want to create a module or code library that you can load and have 
complete access to at runtime as if it's classes were a part of your project 
then you need to create a new LoaderContext using 
ApplicationDomain.currentDomain and use that LoaderContext to load your module. 

Once loaded, you can use a variety of methods to get at the classes. When I do 
this I often have the class names as strings in an XML file that I load so I 
don't need to do any guessing. I simply look up the class name in the xml, then 
use getDefinitionByName(className) as Class and then if that returns a Class I 
simply instantiate that class. But then again I'm loading the library into 
Application.currentDomain because I intend to use it throughout the project and 
have no need to child domain the stuff. 

If you put things into an XML file try to avoid a few things like naming a node 
or attribute "class", I normally use the attribute "class" but as a consequence 
I need to access the attribute using myNode.attribute("class") vs. 
myno...@class since @class will fail because "class" is a reserved word and 
Flex no like that. I'm stuborn and I like to call things what they are, but as 
a consequence I hit the occassional compile error for my stubborness. 

Not sure if that helps you at all. 

Sincerely 
Mark R. Jonkman

[flexcoders] Re: create class on the fly

[postwick]

Yeah, I saw your post in my hours of Googling last night.  Seems very 
promising.  The idea is to have a database table that stores a list of classes 
and their properties, and instantiate them at runtime without having to 
recompile the app - so that if a new class is added to the db my app can use it 
on the fly.

Would your method of using Modules solve this?  It appears so, but I haven't 
had a chance to try it out. In your post you say:

"This setup is very flexible because I can return both instances and classes 
from the Module."

Can you give me an example of how you would return a Class?

You can use anything to the left of the colon you like, as long as you declare 
the XMLNS at the top.

It is not expected that you can just change the namespace and compiler and 
have it work, as far as I am aware.

I suggest you ask them about their Flex 4 plans then. They probably have a 
beta program or something.

Presumably this is more than inspection, it's some sort of 
MPLS/DPI/application protocol security/etc. that rejects unknown (or 
unauthorised) protocols.
I suggest you find their IT bods.

[flexcoders] Re: Issue adding an Image component to a custom component

[gordofeatherfoot]

Hey Alex,

Thanks for your reply.

I solved my issue. for some reason my custom component never got it's 
systemManager set. This is not a problem when all you add to the component are 
Hboxes or labels apparently, but as soon as you add an image the systemManager 
must be set.
All i did was to set it manually in the preinitialize event handler of my 
weather component :

this.systemManager = this.parentDocument.systemManager.

After that it worked like a charm!

Do you know when the systemManager is set in the components lifecycle? Maybe it 
wasn't set because my creation policy was set to "none" ... just a wild guess 
really :-)

Thanks for your help,

Tony.

Re: [flexcoders] Re: "undefined" in stack trace (Console), stack overflow

[thomas parquier]

I think errors can be thrown using a localized string (from a resource
bundle), so I'm not sure but I think a missing translation can cause an
"undefined".

Re: [flexcoders] Re: "undefined" in stack trace (Console), stack overflow (2nd try)

[Erik de Bruin]

Alex,

Well, that's the thing. The code in that method doesn't seem to be the
problem. If I put the seemingly offending line in a try...catch block,
it runs without triggering the catch. And weirder still, the
"undefined" exception happens somewhere a little further in the
flow...

This happens only when I play the piece in AIR on a Mac. AIR on
windows doesn't show this problem and it also doesn't happen when the
code runs in the Flash plugin in a browser (on both platforms). Are
there any known issues that might relate to this?

Thanks again,

EdB

[flexcoders] Re: Issue adding an Image component to a custom component

Thanks for your reply Alex,

Are you refering to an init function that is built into the base flex component 
(ie canvas in this case), because IDSWeather has a custom init() function 
defined. In this function I use createComponentsFromDescriptors(); with a 
creation policy set to NONE.

Since my post i have fiddled around with the code and it doesn't crash but my 
component is empty! It seems that my component has a problem displaying it's 
subcomponents. 

Basically now my IDSWeather component gets added to the stage but it's empty (i 
know this because we have 'handles' around the components that allow us to 
resize them and those are visible). After a given amount of time it changes to 
another state in which an image is added again. When the component wants to 
switch to this state it crashes again with the error i mentionned before. So i 
would say that the component get's added to the stage but as soon as an image 
is added to it, it crashes. Having said this the component doesn't seem to have 
rendered any of it's subcomponents so the problem might be there.

It is really not an easy problem to explain :-) Might i be able to send you 
some source files directly?

Thanks for your help, I've been stuck on this for 2 days and i just can't get 
my head around it.

Best Regards,
Anthony.
