Hello I have an issue with an marker that does not want to close when clicked. Basically adding a marker is fine, but when I click on the marker it is supposed to close but it doesn't. I copied the code from this tutorial.
http://gwt.google.com/samples/HelloMaps-1.0.1/HelloMaps.html#Click%20... Here is my code: public class SimpleMaps implements EntryPoint{ private InfoWindow info = null; private Marker newMarker = null; InfoWindowContent infoWindowContent = null; /** * This is the entry point method. */ public void onModuleLoad() { LatLng cawkrCity = LatLng.newInstance(39.509, -98.434); VerticalPanel verticalPanel = new VerticalPanel(); verticalPanel.addStyleName("verticalPanel"); MapWidget map = new MapWidget(cawkrCity, 4); HTML htmlWidget = new HTML("<b> Write a message </b>"); verticalPanel.add(htmlWidget); info = map.getInfoWindow(); infoWindowContent = new InfoWindowContent(verticalPanel); map.setUIToDefault(); map.addStyleName("mapContainer"); map.setSize("500px", "300px"); # THIS IS THE CLICKHANDLER FOR THE MARKER map.addMapClickHandler(new MapClickHandler() { public void onClick(MapClickEvent e) { MapWidget sender = e.getSender(); Overlay overlay = e.getOverlay(); LatLng point = e.getLatLng(); newMarker = new Marker(point); if (overlay != null && overlay instanceof Marker) { sender.removeOverlay(overlay); } else { sender.addOverlay(newMarker); info.open(newMarker, infoWindowContent); } } }); RootPanel.get("mapContainer").add(map); } I also receive an error when testing this application: 14:37:18.834 [ERROR] [simplemaps] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (TypeError): a is null fileName: http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/maps2.api/main.js lineNumber: 1246 stack: (null)@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:1246 ik(null)@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/maps2.api/ main.js:1237 (null)@http://localhost:8888:85 @:0 ([object GWTJavaObject],2555922,[object GWTJavaObject],null)@http:// localhost:8888/simplemaps/hosted.html?simplemaps:56 ([object Object],(void 0),[object Object])@http://localhost:8888:160 ([object Array])@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:297 ([object Object],1)@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:274 t([object Array],(function (d) {if (lh) {d.bt(c);} else {try {d.bt (c);} catch (f) {}}}))@http://maps.gstatic.com/intl/en_ALL/mapfiles/ 193c/maps2.api/main.js:81 A([object Object],"click",[object Object],(void 0),[object Object]) @http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/maps2.api/main.js: 274 ([object Object])@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:770 ([object Object])@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:6 ([object Array])@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:297 ([object Object],0)@http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/ maps2.api/main.js:274 t([object Array],(function (d) {if (lh) {d.bt(c);} else {try {d.bt (c);} catch (f) {}}}))@http://maps.gstatic.com/intl/en_ALL/mapfiles/ 193c/maps2.api/main.js:81 A([object Object],"click",[object Object])@http://maps.gstatic.com/ intl/en_ALL/mapfiles/193c/maps2.api/main.js:274 Em([object MouseEvent])@http://maps.gstatic.com/intl/en_ALL/mapfiles/ 193c/maps2.api/main.js:1298 at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript (BrowserChannelServer.java:195) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke (ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative (ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject (ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject (JavaScriptHost.java:91) at com.google.gwt.maps.client.impl.__MarkerImplImpl.construct (__MarkerImplImpl.java) at com.google.gwt.maps.client.overlay.Marker.<init>(Marker.java: 116) at simplemap.client.SimpleMaps$2.onClick(SimpleMaps.java:66) at com.google.gwt.maps.client.MapWidget$8.callback(MapWidget.java: 481) at com.google.gwt.maps.client.impl.EventImpl$OverlayLatLngCallback $1.execute(EventImpl.java:193) at com.google.gwt.maps.client.impl.EventImpl.invokeAndReportUncaughtExceptions (EventImpl.java:260) at com.google.gwt.maps.client.impl.EventImpl.invokeAndMaybeReportUncaughtExceptions (EventImpl.java:246) at com.google.gwt.maps.client.impl.EventImpl.access$0 (EventImpl.java:241) at com.google.gwt.maps.client.impl.EventImpl $OverlayLatLngCallback.callbackWrapper(EventImpl.java:191) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at com.google.gwt.dev.shell.MethodAdaptor.invoke (MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke (MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke (OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessages (BrowserChannel.java:1668) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection (BrowserChannelServer.java:401) at com.google.gwt.dev.shell.BrowserChannelServer.run (BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:636) This could maybe be related. I'm sorry for posting all this code. Since it usually unnecessary. But i'm not sure what to do, or where this error/exception lies.
