I get the following error:
Illegal Argument java/lang/IllegalArgumentException Current Displayable is an Alert
I'm not sure what is means and why this exception is fired.
I found an answer on the nokia forum!
It is an exception thrown when calling Display.setCurrent() with an Alert as the argument, while an Alert is already displayed.

I'm using Windows UIAutomation quite heavily and it works mostly well. But it's throwing some exceptions that I haven't been able to figure out.
The first of these is:
Exception thrown at 0x762D46D2 (KernelBase.dll) in MyApp.exe: 0x80040155: Interface not registered.
The offending section of code is the last line of:
IUIAutomationElementPtr element; //This is a valid element
IUIAutomationCacheRequestPtr cachePtr; //This is a valid cache pointer
IUIAutomationElement **first;
HRESULT hr = myControlWalker->GetFirstChildElementBuildCache(element, cachePtr, firstChild);
The second of these is:
Exception thrown at 0x762D46D2 (KernelBase.dll) in MyApp.exe: 0x40080202: WinRT transform error (parameters: 0x80040155, 0x80004002, 0x0000001D, 0x0565DB4C).
which happens at the same line of code as the previous.
And the last is:
Exception thrown at 0x762D46D2 (KernelBase.dll) in MyApp.exe: 0x8001010D: An outgoing call cannot be made since the application is dispatching an input-synchronous call.
once again, from the same line of code.
The program runs fine and it does what it needs to do, it just bothers me to have zillions of these exceptions being thrown left and right. Any suggestions?
I have an existing source code. I have function called upload resource. If i click on upload button and try to upload image file it says following error.
jquery.fineuploader-3.4.1.min.js:4 [FineUploader] Caught exception in 'onComplete' callback - Cannot read property 'split' of null
In View file, Widget is added i.e. ext.EFineUploader.EFineUploader
Anyone have any idea what could be wrong?
The message indicates that there is an error in your onComplete callback function. You haven't posted your code, so there is no way to determine exactly where the error is, but it appears as if you are attempting to split a string, but the string in your code is null for some reason. You'll need to look closer at your code to determine where the error is.
In Lablgtk, whenever there is an exception in a callback, the exception is automatically caught and an error message is printed in the console, such as:
(prog:12345) LablGTK-CRITICAL **: gtk_tree_model_foreach_func:
callback raised an exception
This gives no stack trace and no details about the exception, and because it is caught I cannot retrieve this information myself.
Can I enable more detailed logging information for this case? Or prevent the exception from being caught automatically?
I guess the best way to do so is to catch your exception manually and handle it yourself.
let callback_print_exn f () =
try f () with
e -> my_exn_printer e
Assuming val my_exn_printer : exn -> unit is your custom exception printer, you can simply print your callbacks exceptions by replacing ~callback:f by ~callback:(callback_print_exn f) in your code.
Of course, you can also with that method send that exception to another
thread, register a "callback id" that would be passed along with your exception...
About the stack trace, I'm not sure you can retrieve it easily. As it's launched as a callback, you probably want to know the signal used and that can be stored in your callback handler.
I had another similar issue, but this time it was harder to find where to put the calls to intercept the exception.
Fortunately, this time there was a very specific error message coming from the Glib C code:
GLib-CRITICAL **: Source ID ... was not found when attempting to remove it`
Stack Overflow + grep led me to the actual C function, but I could not find which of the several Lablgtk functions bound to this code was the culprit.
So I downloaded the Glib source, added an explicit segmentation fault to the code, compiled it and used LD_LIBRARY_PATH to force my modified Glib version to be loaded.
Then I ran the OCaml binary with gdb, and I got my stack trace, with the precise line number where the Lablgtk function was being called. And from there it was a quick 3-line patch.
Hacks like this one (which was still faster than trying to find where to intercept the call) could be avoided by having a "strict mode" preventing exceptions from being automatically caught. I still believe such a switch should be available for Lablgtk users, and hope it will eventually be available.
I stumbled upon a very weird issue in ColdFusion which might very well be a bug, but I wanted to post it here in case I was missing something.
It seems that cfindex is throwing an uncatchable exception when trying to index invalid files.
I'm not entirely sure yet what consists of an invalid file, but the issue occurs with a valid PDF file, but that doesn't have a PDF extension. Obviously, the problem can easily be fixed by adding a valid extension, but that's not the scope of the question.
<cftry>
<cfindex
collection="some_collection"
action="update"
key="//someserver/some_file_without_extension">
After index
<cfcatch type="any">
Exception caught
</cfcatch>
<cffinally>
Finally block
</cffinally>
</cftry>
Completed
When running the above code, the only thing that is output is Finally block, therefore it's like if there is an exception thrown, but which cannot be caught.
I even tried with type="java.lang.Exception", type="java.lang.Throwable" and type="searchengine" and nothing works.
The only way I found to detect such exceptions is to check a boolean flag in the finally block, but gracefully recovering form those errors is very cumbersome.
Another very weird thing that occurs is that right after the issue is encountered, if I refresh the page in the browser, I'll get the following error:
HTTP Error 503.0 - Server Error
The service is unavailable.
Module IsapiModule
Notification ExecuteRequestHandler
Handler JWildCardHandler
Error Code 0x00000000
Then after refreshing again, I get Finally block and if I keep refreshing the same behavior occurs over and over (Finally block then 503 error).
I'm working on some flash app. Now, to test customer side of it I can use Flash Player debugger version that will save logs and show error messages. When it's deployed on the customer side - they will have a regular Flash Player version which means I will have no access to error messages if errors will happen. So I would like to equip it with some tool that would capture all of my trace messages in code and errors text. As for trace messages that's fairly simple, I just override the function in my code so it sends a POST request with trace message to a logger server, but how can I get a hold of the error message? Is there a known approach to this or some trick that somebody can suggest?
You can install the debug version of flash as your browser's default (in Chrome, you must disable the built-in player), so if you wanted to test user experience and debug, this would be the ideal solution.
However, to answer your question: there's no method for universally catching all errors, and redirecting them (that I know of). You'd have to encapsulate problem code ahead of time with try...catch statements, and send the property back on catch. For example:
try {
this["foo"]();
} catch (e:Error) {
trace(e);
}
In the debug version, the traced value would be TypeError: Error #1006: value is not a function. And while the standard version will only output TypeError: Error #1006, (a notably less descriptive error), what we're missing is any reference to where the error occured. To get this, we need to use Error.getStackTrace() to see the call stack and the line where the error occurred. In debug, this outputs the following:
TypeError: Error #1006: value is not a function.
at Shell_fla::MainTimeline/init()[C:\Projects\shell.as:91
In the standard client, we get a dissapointing null. In short, you cannot get any valuable info from the client versions.
The best advice I can give is to write around your problem code with your own custom error reports. For example, catch IO errors and trace the file it failed to load, or if you're expecting an object.foo, first try if (object.hasOwnProperty("foo")) { // do something } else { trace("foo not found in " + object.name) }. Code defensively.
Cheers,
I've discovered this post on StackOverflow:
How to catch all exceptions in Flex?
It answers my question, strange that I haven't ran into it while I was googling prior to asking.
