ActionScript 2.0 :: Flex 2: Crash Bug In Canvas.measure?
Oct 6, 2006
The program croaks when measureContentArea (in package mx.containers.utilityClasses, file CanvasLayout.as ) loops through the target's children from 0 to target.numChildren. When the program errors: n == 1, i == 0, and target.numChildren is now 0, when it was 1 before the loop. target.numChildren has changed while the loop is running. It's as if a child was removed by some side effect of calls in the loop.
This happens even when I have many IOComponents on the screen: Here This baffles me because I don't see how I can debug it. I do add and remove and insert children in my game code, but unless ActionScript is threaded I don't see how my code can reach into a loop in CanvasLayout.as .
I want to dynamically add different items to thumbContent canvas and use scroller canvas to scroll. I see than the height of thumbContent bigger than 7977 it truncate from scrolling. So - I see the scroller canvas with empty space on top. Then I scroll to bottom - I see the content of thumbContent and at bottom scrolling I see empty space too.
I'm trying to skin a canvas with an image (which is essentially a custom border for the canvas). I've been trying the backgroundImage style as well as the borderSkin style. I can't get the image to scale to the full size of the canvas though. I was wondering what the best way to go about this is.[code]...
I have a function that is made up of two main parts (I'll call them A and B). Part B needs to run when part A is fully done with its layout changes. However, there is no "part A is done" signal, and thus I've been calling a validateNow() before part B runs. This works but seems awfully inefficient - was wondering if there are any other tricks to force an immediate measure or something along those lines or if I'm stuck.
Is there a way to measure the average time it takes my code to run and each frame to render for my Flex app? More specifically, I know how to use getTimer() but I'm not sure about which events I should listen to in order to do this. I was reading this post and am not sure how you'd figure out how long the actual rendering took (it would seem like it may be the time between the RENDER event fires and the next ENTER_FRAME event fires, but I'm not sure). Also, not exactly sure where the user code happens, or whether I should care about EXIT_FRAME and FRAME_CONSTRUCTED. [code]...
I'm using a List control. In the renderer of the List control I've got a Repeater. Each Repeater can have a different number of items. Adding to the complexity, one of the components being repeated in the repeater is a Text control that has long text that will wrap, increasing it's height. I need to expand the height of the List completely so that there's no vertical scrollbar. How can I do this?
I tried an extremely dirty attempt at calculating the Lists height based on the data source. From the data source I can figure out the number of repeater items and the number of items in each repeater in the List's renderer. But there's no way to compensate for the wrapping of the text in the Text control.
I have a textarea where I measure the textWidth and textHeight to make sure the user cannot enter more text than can fit in the text area. I also extended the textArea with a textHeightNow and textWidthNow that measure the textField's dimensions since they update w/out requiring validation. Now this works great for 90% of the embedded fonts I'm using but any fonts that have giant serifs are not measured properly, for instance look at the 'f's in this text area:You can see they get cut off on both sides because textWidth and textWidthNow both return an incorrect size not taking into account the massive serifs.
have an advanced datagrid with a simple custom mxadvanceddatagriditemrenderer. I want the renderer to only display an image when the row is hovered or selected. Right now I am doing that by using the excludeFrom="normal" tag on my image.
It works fine (minus the selected state, it disappears when selected) when I have the states hovered and normal defined. When I try to define a selected state, upon row click I get the following error:
RangeError: Index 0 is out of range. at spark.components::Group/checkForRangeError()[E:dev4.xframeworksprojectssparksrcsparkcomponentsGroup.as:1106] at spark.components::Group/setElementIndex()[E:dev4.xframeworksprojectssparksrcsparkcomponentsGroup.as:1265]
I am working on a flex project using sharedobjects to store information on my server. I am not 100% sure how to do this, so I was looking up tutorials and came across this bit of code:
nc = new NetConnection(); nc.connect("rtmp://[website here]"); so = SharedObject.getRemote("ballPosition", nc.uri, false);
I've got a flex-based swf, which is loading an AS 2-based swf and then, negotiating further activity via a LocalConnection. From time to time, the AS 2-swf can request that the flex-based swf load a movie. I've arranged this via on(release){} functions. The AS 2-swf, I'm making in Swish Max. In Swish, when I set the on (release) on a text field, (to invoke .send() on my localconnection), it works splendidly. However, when I attempt to perform the same calls for an on(release) attached to a movieclip, it actually causes the Flash player, and even the browser plugin to crash. In fact, the browser (IE) crashes as well. I checked the debug trace that ie asked me to send to microsoft at the last IE crash, and i noticed a StackOverflow exception embedded deep in the trace, but I couldn't determine its source.
I use HTMLLoader component, and I have to load thousand of different websites per days by this component.But some times, HTML component produce several crash/days of my AIR application
I installed the Adobe Flash Builder 4.5 which includes the eclipse plugin.I want 2 use my existing eclipse, so I copied the contents of plugin and features folder to existing eclipse folder.I see the Flex features in Eclipse, but trying to open the Flex Builder Path causes eclipse to crash. Error Message is :
"Please uninstall and reinstall the product
If this problem still occurs, please contact Adobe technical support for help, and mention the error code shown at the bottom of this screen.[code]...
I will be releasing my Air/Flex application soon, but I am pretty sure there are a couple of bugs that may pop up on the various platforms that Air is available for. So I was wondering if there is a way to implement a mechanism, that would send an error report, logging where the error happened, to a remote server each time an app crashes? This way I might catch errors that otherwise would go unnoticed.
I have a flex app using the 4.5.1 sdk and AIR 2.7 running on an Android 3.2 tablet. During use, I can get it to crash fairly regularly. It's usually when I'm rapidly scrolling around in a List control. I can't seem to find the cause.
The application will just suddenly close. It happens in both debug and release builds.
When in debug mode, it just disconnects from the debugger and doesn't give me any useful information.
I'm at a loss on how to debug this. What are some techniques I can use?
I found the "adb logcat" command. Relevant info from the log below, unfortunately it doesn't mean much to me.
since updating my Flash Player plugin from 10 to 10.1, I'm seeing a weird crash when accessing shared objects. Flex Builder's debugger pops up and prints a stack trace like this:
undefined at flash.net::SharedObject$/getLocal() at my.code::MyClass$/load()[/my/path/to/my/MyClass.as:27] (...)
This happens when calling SharedObject.getLocal("someString") for the second time for the same string, though it doesn't always crash. When using another browser on the same machine (not configured as the preferred debugging browser in Flex Builder), Flash Player remains silent. The code is wrapped in a try/catch(Error) block which does not catch this error. I'm using Flex SDK 3.5 and Flex Builder 3 on Mac OS X 10.6.3.

But when it gets to the 3rd line, it crashes. I don't know how to use the debugger for flex sadly enough
Flex charts, like AreaChart, have wonderful built-in support for displaying data "tool tips" when a user hovers over a point supplied in the data of a graph. You can hover over any of the bar graph examples on this page for a demonstration. I have a graph situation where I optionally draw in some dots as reference points on CartesianDataCanvases supplied to my AreaChart through it's <mx:annotationElements> and <mx:backgroundElements> tags.
I would like to have the same hover data-tip functionality that the AreaChart has, but applied to these dots. I realize that I am just drawing on canvas, and that no actual dataProvider supports these dots, but if there was a way to supply the CartesianDataCanvas with an array of data values or something to that effect,
I'm building an Flex 4 application using IntelliJ IDEA 9.0.2 generated sample Flex application. I replace the generated mxml with the following code from the book Hello Flex 4. It simply crashes the browser when I run it. It says "Waiting for [URL]..and then crashes I tried it on both FF 3.5.9 and Chrome 4.
I'm developing an engine to generate components.I been wanting to get my xml script that read and create a component to be load into 'content' canvas. I not sure how do I get the addChild work correctly as in 'content'.addChild instead of the one shown below:[code]
The basis for the chat window is a canvas. I've got that showing, but how do I make it scroll up? I want to clip the window so only the last 15 lines are shown.[code]...
My code above works absolutely fine, until i resize my browser window to a size below 800px width. When the browser window is make of lesser width than 800px, the canvas with background color #A8A8A8 is on the right of the window, but the problem is, when I move the scroll bar, the canvas should remain on the right of the window. Which does not happen, and that is what my problem is.
How can I solve this issue. What should I do to keep my canvas be on the right=0 all the time.
I'm trying to write some code to an animated images of squares on a Flex Canvas There's something wrong with my code below because it becomes progressively slowerI assume I'm supposed to clear the old squares or something.What am I doing wrong below?:
Basically I want to go to frame2 when the cursor leaves the canvas. The code below contains no errors when tested but it still does not work.
[Code]...
We know that the function gotoAndStop(frame2); works in multiple situations which means the first 3 line is fine. I don't know if the problem is the MOUSE_LEAVE event or this.stage which i suppose is the identifier for the canvas. I sure that there must be an alternative code for the identifier this.stage or the whole code. Any solution on how to fire the given function in the event when the cursor leaves the canvas?
i am required to zoom a canvas through Hslider. The problem is after zooming the canvas i cannot scroll to the extreme left and top of the canvas i.e some part of left and top canvas are not visible. i cannot find the reason. The source code for the example is given below.
Is there a way in Flex by which a disabled canvas looks exactly the same as an enabled canvas? I haven't been able to make sense of disabledOverLayAlpha and disabledColor properties for a Canvas component.
a .fla is 500 x 300. Inside, content moves OUT of the 500 x 300 stage so that it appears like it hides or moves off of the screen. .fla complied... loaded into Flex via SWFLoader:
