actionscript 3 - Why isn't my exception being caught? -


this stack trace get:

[fault] exception, information=error: directory id 3 in use @ cantrips.assets.index::assetindex/diridchanged()[/home/luismasuelli/proyectos/flash-assets-index-ritual/assets-index-loader/src/cantrips/assets/index/assetindex.as:72] @ flash.events::eventdispatcher/dispatcheventfunction() @ flash.events::eventdispatcher/dispatchevent() @ cantrips.assets.index::assetdirectory/set id()[/home/luismasuelli/proyectos/flash-assets-index-ritual/assets-index-loader/src/cantrips/assets/index/assetdirectory.as:68] @ main/updateselecteddirectory()[/home/luismasuelli/proyectos/flash-assets-index-ritual/assets-index-editor/src/main.mxml:192] @ main/__dirupdatecurrent_click()[/home/luismasuelli/proyectos/flash-assets-index-ritual/assets-index-editor/src/main.mxml:401]

this implementation of main/updateselecteddirectory():

    private function updateselecteddirectory():void {         try {             var newid:uint = uint(dirid.text);             var newname:string = stringutil.trim(dirname.text);             var selecteddirectory:assetdirectory = assetbrowsertree.selecteditem assetdirectory;             if (selecteddirectory) {                 selecteddirectory.id = newid;                 selecteddirectory.name = newname;                 assetbrowsertree.expanditem(selecteddirectory.parent, false);                 assetbrowsertree.expanditem(selecteddirectory.parent, true);             }         } catch (error:error) {             alert.show(error.message, "cannot update");         }     }

why not exception being caught try {} catch(error:error) {}?.

the exception exception created me, well-understood scenario triggered (i created exception , designed scenarios , testing them; exception triggered expect). tried using exact name of exception (assetindexerror) in catch block, , no confusion or ambiguous name exists (this means: there's no assetindexerror class declared elsewhere importing instead of this).

explanation:

  • cantrips.assets.index code have control over.
  • main/* main window. have control on code.

screenshot:

if @ stack, you'll see error not being thrown in code shown (which near bottom of stack), here:

diridchanged @ assetindex.as:72

further down in stack you'll see following:

at flash.events::eventdispatcher/dispatchevent()

this means stack asynchronous in between assetdirectory.set id() , assetindex.diridchanged()

when add event handler, code in current block run prior event handler code (as not in same thread).

so in case, code in try/catch have run before event handler's code - why error not being caught.

any time handling event, need have try/catch, or use asynchronous error handling technique.
