gwt-1.2.3 RootPanel.get("main").remove(viewport_instance)

[Shawn.in.Tokyo]

I can't run hosted mode under gwt-1.2.3 as I get an inexplicable error, a really really inexplicable error. It works fine under 1.2.2.

At one point in my code, I access a static variable. Fine. A moment later I use the same getter method to access it again and get a null value erroneously returned.

There is nothing in my code that could be setting the value to null. Again it works under 1.2.2. It's just whack.

I did notice a very odd thing that if I comment out the following code to clear a Viewport from the RootPanel that immediatly precedes my getter call, my unrelated getter call works as it should:

//try{
//RootPanel.get("main").remove(auto_resize);// auto_resize is a Viewport
// }catch(Exception e) {
// Log.info(e.getMessage());
// }catch(Error e) {
// Log.info(e.getMessage());
// }

But if there were an error, why doesn't the try catch clause contain it? Am I not catching correctly?

There is no way my getter can be returning null. Actually, the getting is throwing the strange error above. Why does removing a Viewport from the RootPanel cause an unrelated static to be unaccesable?

A viewport was never made to be removable, but we already reverted the change made to viewport in SVN.

What else, if I may ask, isn't designed to be removed?

Anyway, thanks for your response.

All the Best,

Well isnt designed is maybe the wrong word. Wasnt thought about make it better. 1.2.4 will make it work.
