I posted this question on StackOverflow <http://stackoverflow.com/questions/27533785/gwt-googlemaps-hide-default-layers-using-styles>, but I haven't received any answers, so I'm posting here.
I'm using GWT and GoogleMaps (v3.8.0 <https://code.google.com/p/gwt-google-apis/downloads/list>), which I have working fine. But now I'm trying to use MapTypeStyle to set the styles of the roads to off. Here is some example code: package com.test.client; import com.google.gwt.ajaxloader.client.AjaxLoader; import com.google.gwt.ajaxloader.client.AjaxLoader.AjaxLoaderOptions; import com.google.gwt.core.client.EntryPoint; import com.google.gwt.core.client.JsArray; import com.google.gwt.dom.client.Document; import com.google.maps.gwt.client.GoogleMap; import com.google.maps.gwt.client.LatLng; import com.google.maps.gwt.client.MapOptions; import com.google.maps.gwt.client.MapTypeId; import com.google.maps.gwt.client.MapTypeStyle; import com.google.maps.gwt.client.MapTypeStyleElementType; import com.google.maps.gwt.client.MapTypeStyleFeatureType; import com.google.maps.gwt.client.MapTypeStyler; public class GwtTest implements EntryPoint { @Override public void onModuleLoad() { AjaxLoaderOptions options = AjaxLoaderOptions.newInstance(); options.setOtherParms("sensor=false"); Runnable callback = new Runnable() { public void run() { createMap(); } }; AjaxLoader.loadApi("maps", "3", callback, options); } public void createMap() { JsArray<MapTypeStyle> styles = (JsArray<MapTypeStyle>) JsArray.<MapTypeStyle>createArray(); JsArray<MapTypeStyler> roadStylers = (JsArray<MapTypeStyler>) JsArray.<MapTypeStyler>createArray(); MapTypeStyler roadStyler = MapTypeStyler.visibility("off"); roadStylers.push(roadStyler); MapTypeStyle roadStyle = MapTypeStyle.create(); roadStyle.setStylers(roadStylers); roadStyle.setFeatureType(MapTypeStyleFeatureType.ROAD); roadStyle.setElementType(MapTypeStyleElementType.ALL); styles.push(roadStyle); final MapOptions mapOpts = MapOptions.create(); mapOpts.setZoom(4); mapOpts.setCenter(LatLng.create(37.09024, -95.712891)); mapOpts.setMapTypeId(MapTypeId.TERRAIN); mapOpts.setStreetViewControl(false); mapOpts.setStyles(styles); final GoogleMap map = GoogleMap.create(Document.get().getElementById("map_canvas"), mapOpts); } } However, when I run that code, I get this error: 11:18:11.195 [ERROR] [gwttest] Uncaught exception escaped java.lang.ExceptionInInitializerError: null at com.test.client.GwtTest.createMap(GwtTest.java:42) at com.test.client.GwtTest$1.run(GwtTest.java:25) at com.google.gwt.ajaxloader.client.ExceptionHelper.runProtected(ExceptionHelper.java:36) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:172) at com.google.gwt.dev.shell.BrowserChannelServer.reactToMessages(BrowserChannelServer.java:293) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:547) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:364) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException: null at com.google.maps.gwt.client.MapTypeStyleFeatureType$.register(MapTypeStyleFeatureType.java:227) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) 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:172) at com.google.gwt.dev.shell.BrowserChannelServer.reactToMessagesWhileWaitingForReturn(BrowserChannelServer.java:338) at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:219) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:136) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:576) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:284) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.maps.gwt.client.MapTypeStyleFeatureType$.create(MapTypeStyleFeatureType.java) at com.google.maps.gwt.client.MapTypeStyleFeatureType$.<clinit>(MapTypeStyleFeatureType.java:39) at com.test.client.GwtTest.createMap(GwtTest.java:42) at com.test.client.GwtTest$1.run(GwtTest.java:25) at com.google.gwt.ajaxloader.client.ExceptionHelper.runProtected(ExceptionHelper.java:36) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) 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:172) at com.google.gwt.dev.shell.BrowserChannelServer.reactToMessages(BrowserChannelServer.java:293) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:547) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:364) at java.lang.Thread.run(Thread.java:745) The weird thing is, that's an error while initializing a static variable internal to GWT GoogleMaps! Am I doing something wrong, or is this a bug? Is there a workaround? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
