Hello All, We recently migrated from PCs having Windows XP to Windows 7 64-bit in our organization.
My machine has Windows 7 64bit, IE 8 (both 32-bit and 64-bit) & GWT 2.4.0. Our Application used to work perfectly on Windows XP (before migration) and the app uses fair amount of GwtExt as well. However, the same app is not working on Windows 7 in some strange situations. E.g. In a panel, we have a close button (with a cross image) on the panel header which closes the panel. When I click on this button, it throws a Java script error in IE as follows :- Error : "Object doesn't support this property or method" File : hosted.html Also, I get a weird JavascriptException thrown in the stacktrace of GWT HostedMode screen as follows :- 00:02:45.090 [ERROR] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (Error): Unspecified error. number: -2147467259 description: Unspecified error. at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java: 237) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java: 129) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java: 561) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java: 269) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java: 91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java) at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:214) at sun.reflect.GeneratedMethodAccessor67.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java: 43) at java.lang.reflect.Method.invoke(Method.java:601) 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.BrowserChannelServer.reactToMessages(BrowserChannelServer.java: 281) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java: 531) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java: 352) at java.lang.Thread.run(Thread.java:722) I searched about this a lot on the net, found a few threads, but none could help. I am using JDK 7 64-bit and IE 32 bit with GWTDevPluginx86 installed. I DON'T HAVE CHROME FRAME INSTALLED AS WELL. Any help would be appreciated as this is an urgent issue.
