I am trying to integrate google maps into a large java/FDS app I am working on. To make a prototype, I have constructed the following example:
APPLICATION MXML: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"> <mx:Script> <![CDATA[ import mx.managers.PopUpManager; private function popup():void { PopUpManager.createPopUp(this, MapPopup, true); } ]]> </mx:Script> <mx:Canvas width="100%" height="100%"> <mx:Button label="popup" click="popup()" /> </mx:Canvas> </mx:Application> MAPPOPUP MXML <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:maps="com.google.maps.*" xmlns:mx="http://www.adobe.com/2006/mxml"; width="400" height="300"> <maps:Map width="100%" height="100%" key="MY SITE KEY"/> </mx:Canvas> If you run this app and click the popup button, you will get the following stack trace: TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.google.maps::Map/drawBackground() at com.google.maps::Map/onAdded() at flash.display::DisplayObjectContainer/addChildAt() at mx.core::UIComponent/http://www.adobe.com/2006/flex/mx/internal:: $addChildAt()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core \UIComponent.as:5061] at mx.core::Container/addChildAt()[E:\dev\3.1.0\frameworks\projects \framework\src\mx\core\Container.as:2208] at mx.core::Container/addChild()[E:\dev\3.1.0\frameworks\projects \framework\src\mx\core\Container.as:2140] at mx.core::Container/createComponentFromDescriptor()[E:\dev \3.1.0\frameworks\projects\framework\src\mx\core\Container.as:3674] at mx.core::Container/createComponentsFromDescriptors()[E:\dev \3.1.0\frameworks\projects\framework\src\mx\core\Container.as:3486] at mx.core::Container/createChildren()[E:\dev\3.1.0\frameworks \projects\framework\src\mx\core\Container.as:2582] at mx.core::UIComponent/initialize()[E:\dev\3.1.0\frameworks\projects \framework\src\mx\core\UIComponent.as:5341] at mx.core::Container/initialize()[E:\dev\3.1.0\frameworks\projects \framework\src\mx\core\Container.as:2519] at MapPopup/initialize()[/Users/mreynolds/Documents/gatewayworkspace/ GoogleMapsTest/src/MapPopup.mxml:0] at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/ internal::childAdded()[E:\dev\3.1.0\frameworks\projects\framework\src \mx\managers\SystemManager.as:1639] at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/ internal::rawChildren_addChildAt()[E:\dev\3.1.0\frameworks\projects \framework\src\mx\managers\SystemManager.as:1689] at mx.managers::SystemManager/addChild()[E:\dev\3.1.0\frameworks \projects\framework\src\mx\managers\SystemManager.as:1225] at mx.managers::PopUpManagerImpl/addPopUp()[E:\dev\3.1.0\frameworks \projects\framework\src\mx\managers\PopUpManagerImpl.as:263] at mx.managers::PopUpManagerImpl/createPopUp()[E:\dev\3.1.0\frameworks \projects\framework\src\mx\managers\PopUpManagerImpl.as:178] at mx.managers::PopUpManager$/createPopUp()[E:\dev\3.1.0\frameworks \projects\framework\src\mx\managers\PopUpManager.as:124] at GoogleMapsTest/popup()[/Users/mreynolds/Documents/gatewayworkspace/ GoogleMapsTest/src/GoogleMapsTest.mxml:87] at GoogleMapsTest/___GoogleMapsTest_Button1_click()[/Users/mreynolds/ Documents/gatewayworkspace/GoogleMapsTest/src/GoogleMapsTest.mxml:100] I have seen one other post on this forum that included this error and no resolution was posted. In my real app, I am simply trying to add a map to a tab of a tab navigator of the main application view and I get this same error. I am not trying to call any functions or methods on the map, the map has no ID, no listeners, nothing. Still, I can't get a map to even initialize, let alone do anything with it after that point. If I move the map mxml tag into the main application, instead of in this popup in the example, it works fine. Can anyone help me? This issue seems quite easy to reproduce and I feel it has been overlooked. I would like to use google maps in my flex app!! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API For Flash" group.
