Re: GWT and Map dynamic loading
Hello, I still have the problem. I tried to load other scripts and it works. There is a mechanism from JS maps API that i may not understand or know. I should not be the only guy trying this...

Re: GWT and Map dynamic loading
i would use appropriate API for either maps but control them from above, from the DOM of the browser, so first I'd create two DIV containers and bind GMaps or OpenLayers to each, depending on the user selection you can make the one or another container invisible, BUT you should not consider to clean or remove the maps widgets from the DOM, just make them disappear by CSS. as for loading JS code on demand, I'd rather write this subroutine in JSNI then callback the GWT part to pass control over, this way you hide the dirty things from GWT - it will work for sure. So just write your SCRIPTing tag JS loader but in JavaScript as native method.

Re: GWT and Map dynamic loading
maybe you make a change to a DOM node what GWT is aware of and
therefore triggers module unload?
try following function (ready to use) define the function inside JSP
script
function loadJS(url){
var loaderNode = document.createElement(script);
loaderNode.setAttribute(id,ffxep);
loaderNode.setAttribute(type,text/javascript);
(document.getElementsByTagName(head)[0]).appendChild(loaderNode);
loaderNode.setAttribute(src,url);
}
/script
and put invoker to your GWT class:
public native void loadJS(String url)/*-{
$wnd.loadJS(url);
}-*/;
ensure you have the HEAD tag in your html, and give it a try
it has to work...

Re: GWT and Map dynamic loading
I just tried this and it doesn't work, same problem.
I had already tried a similar thing but the JSNI was implemented in
GWT code, same problem anyway :)
I tried to put a javaScript file with basic code on tomcat and it
succed. So the problem doesn't come from the way i load the script.
I think the problem comes from the maps' javascript combined with
dynamic load from GWT. From the javaScript i try to load, there is
other call to scripts, maybe it's a problem... I think there's a
mechanism that i'm not aware.

Re: GWT and Map dynamic loading
this indeed could be the case, never seen that such things refuse to
work - but we're ont done yet, please try to defer loading the script
upon button click - just to be sure browser loaded and initialized, so
create a button and load the script from that onClickHandler()
if still would ont work, then I'd blame maps' script ;) btw. when
serioously think about loading js on demand I'd suggest to try out
RequireJS rom http://requirejs.org/

Re: GWT and Map dynamic loading
It's the same when i load on a button click.
I ll take a look at requireJS.

GWT and Map dynamic loading
Hello, In my application, users can choose between two different map : google map or OpenLayers. I'd like to load dynamically the chosen one by loading the corresponding script (in this exemple google map). I tried this (in the EntryPoint) : ScriptElement script1 = Document.get().createScriptElement(); script1.setType(text/javascript); script1.setSrc(http://maps.google.com/maps? file=apiv=2sensor=falsekey=ABQIpOR5tulUc5y1R6lOKFkbpRTwM0brOpm- All5BF6PoaKBxRWWERTqbaRJ6lpQdSlaltvv3tD-fLXwvQ); Document.get().getElementsByTagName(head).getItem(0).appendChild(script1); ScriptElement script2 = Document.get().createScriptElement(); script2.setType(text/javascript); script2.setSrc(http://mapstraction.googlecode.com/svn/trunk/source/ mxn.js?(google)); Document.get().getElementsByTagName(head).getItem(0).appendChild(script2); This code makes my application unloading... (message : Unloading module). I don't understand the problem. Is there a way to realize this ?

Re: GWT and Map dynamic loading
That error message doesn't look familiar. Where do you see the message? Are you running in development mode or web mode? If you want to dynamically load the Google Maps API, you can use the gwt-google-apis maps library Maps.loadMapsApi() method: http://gwt-google-apis.googlecode.com/svn/javadoc/maps/1.1/com/google/gwt/maps/client/Maps.html or the AjaxLoader classs directly: http://gwt-google-apis.googlecode.com/svn/javadoc/ajaxloader/1.1/com/google/gwt/ajaxloader/client/AjaxLoader.html If you want to see how Maps.loadMapsApi to injects a script tag, take a look at the implementation of the AjaxLoader class. http://www.google.com/codesearch/p?hl=en#ow6Lmd7dcZY/trunk/ajaxloader/ajaxloader/src/com/google/gwt/ajaxloader/client/AjaxLoader.java It is pretty much the same, only it puts the script tag on the BODY element, and has logic to wait for the tag to be loaded by using a callback.

Re: GWT and Map dynamic loading
Hello, I'm trying this in hosted mode (development mode). I can see this error in the Eclipse console. If i use Goodle map API, i will not be able to load the other king of map i need to use. I tried many way to load these javascript files dynamically with an URL as argument but it's always the same error. Module is loading normaly and when the code is reached, it unloads the application.

Re: GWT and Map dynamic loading
The gwt-maps API allows you to defer loading of the Maps API. The Maps API will not actually be download until you call Maps.loadMapsApi() Regardless, what I think is happening is that your code is failing in a static initializer or before the onModuleLoad() returns. One way to debug this is to put all of your startup logic into a different method, and then invoke the method via a Timer or DeferredCommand. if your code is failing before onModuleLoad() returns, you'll likely get a better stack trace. You can also just set your IDE debugger to stop in onModuleLoad and trace through it until it throws an exception.
