    A fatal exception occurs when selecting an annotation that has an instance of Ti.UI.View passed as the rightView parameter. - This error doesn't occur if you pass an instance of ImageView as rightView and leave leftView unset. The image view is displayed as expected. - It does occur if you specify the Ti.UI.View instance as either leftView or rightView, and set the ImageView as the other view. - It doesn't occur if you set a Ti.UI.View instance to leftView and leave rightView unset. Although in this case, the view still isn't displayed. Test case: {code} var win = Titanium.UI.createWindow({ modal : true, backgroundColor : 'white' }); // an image view... var pane = Ti.UI.createImageView({ image : 'pin2.png', width : 30, height : 30 }) // and a plain view var plain = Titanium.UI.createView({ width : 20, height : 20, backgroundColor : '#336699' }); var atlantaParams = { latitude : 33.74511, longitude : -84.38993, title : "Atlanta, GA", subtitle : 'Atlanta Braves Stadium\nfoo', pincolor : Titanium.Map.ANNOTATION_GREEN, animate : true, // leftView : pane, rightView : plain }; var atlanta = Titanium.Map.createAnnotation(atlantaParams); // CREATE MAP VIEW // var mapview = Titanium.Map.createView({ mapType : Titanium.Map.STANDARD_TYPE, region : { latitude : 33.74511, longitude : -84.38993, latitudeDelta : 0.5, longitudeDelta : 0.5 }, animate : true, regionFit : true, userLocation : true, annotations : [atlanta] }); mapview.selectAnnotation(atlanta); win.add(mapview); win.open(); {code} Stack trace: {code} E/AndroidRuntime( 1387): FATAL EXCEPTION: main E/AndroidRuntime( 1387): java.lang.NullPointerException E/AndroidRuntime( 1387): at ti.modules.titanium.map.TiOverlayItemView.setItem(TiOverlayItemView.java:191) E/AndroidRuntime( 1387): at ti.modules.titanium.map.TiMapView.showAnnotation(TiMapView.java:493) E/AndroidRuntime( 1387): at ti.modules.titanium.map.TiMapView.doSelectAnnotation(TiMapView.java:727) E/AndroidRuntime( 1387): at ti.modules.titanium.map.TiMapView.handleMessage(TiMapView.java:471) E/AndroidRuntime( 1387): at android.os.Handler.dispatchMessage(Handler.java:95) E/AndroidRuntime( 1387): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 1387): at android.app.ActivityThread.main(ActivityThread.java:4627) E/AndroidRuntime( 1387): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 1387): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 1387): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) E/AndroidRuntime( 1387): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) E/AndroidRuntime( 1387): at dalvik.system.NativeStart.main(Native Method) {code} Given the peculiar left/right behavior, I noted that the line we crash on, TiOverlayItemView.java:191: 191 rightPane.addView(rightView.peekView().getNativeView()); Does not match the corresponding code for leftView: 167 leftPane.addView((leftView.getOrCreateView()).getNativeView()); Although otherwise the handling of these views appears to be identical. Also, I wonder if this behavior explains some of the peculiarities reported in TIMOB-5038, where the annotation is not being updated.
