I started to have this error that i cannot trace back to my app (i use "org.eclipse.nebula.widgets" NumberFormatter, that woked pretty well in previous versions of Eclipse).

This error does not seem affect anything crucial...

Thanks.

Hi Marco,

Something wrong in the preference page that is opened by the rcpcolibri
action?

Regards,

Wim

Hello!

I am having the same problem.

I use the Nebula NumberFormatter with databinding and get the same exception when:

- Select all text in the textbox and press DEL or entering a small number
- Go to the end of the string and press BACKSPACE

However, all data is consistent and the exception does not affect the logic of my code.

Though, it is not very nice Wink

I found a documented bug at
https://bugs.eclipse.org/bugs/show_bug.cgi?id=318782
that describes the same errornous behavior. They say that it is fixed, but i don't really think so?

My Eclipse Version:
Version: Helios Service Release 2
Build id: 20110301-1815

The Exception:

Exactly my problem.

Still not fixed on the latest Eclipse release: Indigo M6a (Build id: 20110319-2305)

Using Windows XP SP3. I will test also in Ubuntu and OS X.
