Hi,
because I cannot access a variable in the enclosing block from within
an AsyncCallback method I found the following workaround with a class
global variable, which I find very unpretty. How can one do this
better?
String tmp_str_usr = "";
String getUser ()
{
SystemServiceAsync svc = GWT.create (SystemService.class);
svc.getUsr
(
new AsyncCallback<String>()
{
public void onFailure(Throwable caught)
{
Window.alert("server side failure: " + caught);
}
public void onSuccess(String usr)
{
tmp_str_usr = usr;
}
}
);
return (tmp_str_usr);
}
