Justin Mclean resolved FLEX-23781. ---------------------------------- Resolution: Fixed Fix Version/s: Apache Flex 4.10.0 Checked into Apache Flex 4.10.0 develop branch > Error #1009 after assigning null to mx:Image source property > ------------------------------------------------------------ > > Key: FLEX-23781 > URL: https://issues.apache.org/jira/browse/FLEX-23781 > Project: Apache Flex > Issue Type: Bug > Components: mx: Image > Affects Versions: Adobe Flex SDK 4.0 (Release) > Environment: Affected OS(s): Mac > Affected OS(s): Mac OS 10.6 > Browser: Safari > Language Found: English > Reporter: Adobe JIRA > Assignee: Justin Mclean > Priority: Minor > Labels: easyfix, easytest > Fix For: Apache Flex 4.10.0 > > > Steps to reproduce: > 1. Compile a debug build of attached Main.mxml > 2. Start fdb and listen for debugging session. > 3. Open swf in a web browser (e.g. Safari). > 4. Click "Click me!" button. > Actual Results: > No errors. > > Expected Results: > [RTE] > TypeError: Error #1009: Cannot access a property or method of a null object > reference. > at > mx.controls::SWFLoader/contentHolder_addedHandler()[E:\dev\4.x\frameworks\projects\framework\src\mx\controls\SWFLoader.as:2543] > > [/RTE] > Error #1009 has occurred: > [Fault] exception, information=TypeError: Error #1009: Cannot access a > property or method of a null object reference. > Execution halted in 'Main.swf' at 0xffffffff (-1) > (fdb) bt > #0 this = [Object 610014329, > class='mx.controls::Image'].SWFLoader/contentHolder_addedHandler(_arg1=[Object > 474409377, class='flash.events::Event']) at <null>:0 > -- > I suspect that in mx:SWFLoader.unloadContent(), contentHolder is not a Loader > and the contentHolder_addedHandler listener is not removed. Hence if > Event.ADDED is dispatched when contentHolder is null, the last line in > contentHolder_addedHandler causes the #1009 error. > This was working at Flex 4 Beta 1. > Workaround: > Since we're using embedded images in this case, we can use s:BitmapImage > instead of mx:Image (which subclasses SWFLoader): > <s:BitmapImage id="sample1" /> -- This message is automatically generated by JIRA.
