ActionScript 3.0 :: ClassCast Exception In Loaded SWF?

Aug 25, 2009

I'm developing a menu driven application with flex and php (ZendFramework). The menu is my main swf, each form is an extra swf loaded with SWFLoader. For the communication with php I'm using AMF3 value objects.My problem is that I get a class cast exception with these value objects, if the form swf is loaded once again.menu item one with a data grid is selected, every operation in the data grid is possible menu item two is selected menu item one is selected once again: any operation in the data grid causes a class cast exception.I tried two different ways of class cast:

var po:pmsPOsVO = pmsPOsVO(dataGridPOs.selectedItem);var po:pmsPOsVO = dataGridPOs.selectedItem as pmsPOsVO; 
The first method is causing the following error:

ActionScript 3.0 :: Adding Controls Causes Exception

May 3, 2010

I'm having trouble adding any instance of the fl.controls to my class.

Compiling does work. And even in debug-mode it passes the moment, when the control is added to the mc. But then during runtime - I guess it happens before the controls have to be displayed - I get something like a null-reference exception. Either it's error 2007 (experianced with ProgressBar) or it's 1009 (experianced with RadioButton).
 
It's exactly the same problem which is described in the comments of the ProgressBar documentation.

package
{
import flash.display.Sprite;
import fl.controls.ProgressBar;

[Code]....

So how can I use fl.controls without having to provide them through the .fla library?

ActionScript 3.0 :: Exception From Library With No Code

Dec 23, 2009

Been so long I haven't write anything here in the forum. I have a big FLA file containing a huge symbol with lots of subsymbols on it. The structure is crazy however there is no even a single line of code in the FLA. The big symbols is exported for actionscript, is associated with some class (say TheSymbol) and its base class is set to MovieClip. I publish the big FLA file to SWC file and link the SWC to project with "Merge into code" linkage type.

ActionScript 3.0 :: Range Exception Handling?

Sep 3, 2011

Code:
for (i=1; i<9; i++) {
if (this["blank"+i].getChildAt(0) is Letters) {
word += this["blank"+i].getChildAt(0).letter;
}
}

This code throws a range exception if, for instance, "blank2" doesn't contain any children.I just need to be able to basically say, "if this blank doesn't have any children, just skip this code."Normally I would do something along the lines of an if=null statement, but this won't work here because

Code:
if (this["blank"+i.getChildAt(0) != null)

obviously throws the same range exception.How do you deal with this? I can't find anything along the lines of a "does blank1 contain any children" sort of method.R

Flex :: Iframe - Catching An Exception Thrown By An Embed URL

May 23, 2011

I am new in Flex, and I am trying to retrieve info from an external url's information. So right now I am using a call a url from another server when the user clicks on the link( this brings up the IFrame with the url embeded). If successful (based on arguments sent with the url) then a correct page will load up. But, if unsuccessful, ( i will get a exception error on the webpage embeded on the link i have given) then i need to display a pop up that says error and return back to the previous page. Is there a way to check if i am getting an exception error from the url site i am retrieving?

Is this possible to load the urls info first and if success then load, and if not bring pop up? ** additional note, I am trying to catch a servlet exception http 500. Below is a peice of the code, so when this component is called, by a click button, it puts this IFrame in the view contents with the url, but i want to know if the http status code is recieving 500, or 400 etc. so i can stop this call and load up instead a error popup.

Flex :: LocalConnection AsyncError : Dispatched When An Exception Is Thrown Asynchronously?

Nov 6, 2010

I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:

asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.

However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.

Python :: Flash - Handle Faults/exception In Flex In Http Requests?

Mar 15, 2012

Here is an issue i'm struggling to solve for quit some time now.I have a python + GAE backend with a flex client that communicates via JSON. I'm using flex's HttpService bound to a Responder with result and fault callbacks. When python raises an exception, I don't seem to get it in flex. I did some research and found out that the problem probably lies in the fact that the flash runtime cannot handle http responses with status code other than 200.

Professional :: Exception Thrown In Destructor CS5 When Using "UNDO" Command?

Apr 22, 2011

I'm assisting my professor with a class helping students build an online portfolio. Yesterday, one of the students sent me a bunch of .fla files to review and I made some changes, inserted a bunch of comments in the code and told her to change the rest of her files into the same format. (Adding keyframes, frame labels and button codes, etc.)
 
Then she emailed me to tell me that she keeps getting this error message every times she makes a mistake and tries to "undo" something.
 
"Every time I open up the drawing page and another one of my subpages like logo design for example, I work on what you said to do, but if i make a mistake and undo it, I get this error message and all my images disappear completely from the time line. I have attached a screenshot of the error message, maybe you know whats going on but I'll keep working on it and try to not have to undo something because at the moment that seems to be the problem. I have to close flash and reopen everything to make it go away."
