I followed this article to use hostpage to pass an array to client:
https://developers.google.com/web-toolkit/articles/dynamic_host_page Currently,I can see follow content in firebug <html style="overflow: hidden;"> <head> ...... <script type="text/javascript"> var rcmdFriends=[{"Name":"Friend-0","Image":"url"}]; </script> </head> ...... </html> Then I tried to use these code to get js variable(a json array actually) from hostpage and print it to user: //get array from host page private native JsArrayExt<People> getRecommendedFriends()/*-{ return $wnd.rcmdFriends; }-*/; @Override public void onModuleLoad() { final FlowPanel fPanel = new FlowPanel(); JsArrayExt<People> channels = getRecommendedFriends(); for (int i = 0, len = channels.length(); i < len; i++) { //"print" name to user fPanel.add(new Label(channels.get(i).getName())); } RootPanel.get().add(fPanel); } //model definition @SingleJsoImpl(PeopleImpl.class) public interface People extends HasName { String getImage(); void setImage(String Image); } But got this eror: java.lang.ClassCastException: com.google.gwt.core.client.JavaScriptObject$ cannot be cast to com.pkg.People Strangely,I can already see the length of "channels" is 1,and why do I get this casting error?How to solove this problem? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
