IE8 KeyPressFilter problem

[eugene_kr]

First of all, I apologize for my English.
Application is not loaded in IE 8.0 using setKeyPressFilter("[]") in TextItem.

In Chrome 14.0.835.186 and Firefox 5.0.1 works fine. I've tried to use <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"> and <meta http-equiv="X-UA-Compatible" content="IE=7"> and <meta http-equiv="X-UA-Compatible" content="IE=8">. Result is the same.

Version: SC_SNAPSHOT-2011-10-04
GWT: 2.3.0

What are you hoping that that regexp would do? It seems to specify a character length of one but no characters are legal - technically a valid regexp (which never matches) and technically IE's bug for rejecting it, but what's the point?

[eugene_kr]

Let me try to explain the idea. I want to disable printing of any characters, but I do not want to disable the field. More specifically, I want to prevent a user to change the current value (type or paste). I know it's not clear to the user. But I need to implement this behavior.
- If I disable the field it will change the appearance.
- If I use InputTransformer (returning the previous value) when the new symbol appears for a moment and then disappears.
- If I use KeyPressHandler I need to check the buttons that do not change the value (Esc, Tab, Enter, ...).
In general, the problem is not implementation the required behavior, but a different behavior in different browsers.
The meaning of "[]" - "no characters". Not technically but in the sense. By analogy with the expression of only digits "[0-9]", but empty.
I do not like the fact that in Chrome and Firefox the regexp works as expected. And in IE 8 application do not even start.

Use ChangeEvent and cancel() the change.
