Hi, currently I'm migrating my GWT1.5 app to GWT1.6.
In Firefox everything was just fine - after handling some incubator stuff (I use ScrollTable and SliderBar) and changing listeners to handlers, my webapp worked perfectly. The problem is, I can't make it work in IE6, which all of my customers use. The first thing I realize is the performance - with GWT1.5 it took my webapp about 3 or 4 seconds to initialize and load the data needed. Now it takes between 25 and 30 seconds and sometimes even more - and I didn't make any changes other than migrating. Why has it become so slow? I mean, I can't really present my users an update, if the app ends up being so slow. The second thing, which really puzzles me, goes like follows: I have a widget, extending a VerticalPanel, which consists of a Label, a Button and a ListBox. If you click on the Button, a PopupPanel is shown, where you can select some data. When you close the popup, the listbox shows the selected data. The strange thing is: if I instantiate this widget up to 8 times, the application works, slowly, but it works. If I instantiate it one more time, IE6 will not react to ANY user input - I can click whereever I want, it behaves as if no javascript is called. Even the site's menu, which is outside GWT, as a header called from the HTML-page, and used to go to other HTML/perl sites will not work(it shows, but clicking it has no effect). Anyway IE6 does not show any error, nor does firefox. If I put a Window.alert() in my widget's constructor - this doesn't happen, the application works, even if I instantiate it more often. I really don't know what to do, in FF3 it is fast and always behaves like expected. Can anybody give me a clue, where I could further investigate? BTW: The data from the server is exchanged through JSON, not RMI with servlets. I'm aware that this might not be optimal for performance(as I always have to parse), but so far this hasn't really been a problem. But maybe it is related to the performance problem?
