I'm currently using Ubuntu 10.10 and Netbeans 7.0 and I can't type accented letters with dead keys any more. It's not a version specific problem seems it's related with Swing since I've got the same problem with older version of Netbeans and OS...
When I type '+a on any app on Linux I get a á vowel. All Linux apps are working fine, but Netbeans doesn't. When I type '+a on Netbeans I get a a vowel (no accent). I cant type quotes and double quotes either.
But I got accents on Netbeans using the right Alt key. (that's not what I want)
At terminal I got the following locale:
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
'+would be an input method. Input methods are processed by each application, so whether they work depends on what libraries the application uses. I don't know what input method uses'+or whether Netbeans can be made to use it. – Gilles May 11 '11 at 21:15
