Is it possible to add/create new history token from every class? I have the problem, that i get NullPointerException if i try to create new token (History.newItem("infoTab")
) outside the main class (the main class contains the onModuleLoad() method). Here the error message:
09:45:11.890 [ERROR] [com.mycompany.client.AdminInterface] Unable to load module entry
point class com.mycompany.client.entries.MainEntry (see associated exception for details)
edit: the iframe part was not added in the index.html. After adding it, i get following:
11:16:48.885 [ERROR] [com.mycompany.client.AdminInterface] Error while executing the JavaScript provider for property 'user.agent'

Line 110 from MainEntry is:
searchButton = new Hyperlink("Search", SEARCH_ID);
so i can't really understand, what is wrong...whithout the iframe i get five history tokens added successfully as follow http://localhost:8080/client/index.html#token1.
It works with and without the iframe tag in my index.html. My mistake was, that i use the url query parameters wrong...after the # :)
