Unable to use dead keys with java and ibus

[Eric Hartmann]

Using latest Lucid packages, I am unable to use ^ key to generate ê french character in every Java programs (jEdit, Netbeans, etc.).

Typing ^ + e give just the e character.
Typing ^ + Space and nothing appears.

I've tried with Sun JDK (6u18, 6u20, 7) and the bug is still present.

I've tried to remove ibus and everything works again (I've just unset XMODIFIERS and GTK_IM_MODULE).

I don't know if it's an ibus bug or openjdk one.

seems to be independent of the java version

[Peter Lundqvist (peterl)]

I can confirm this as well - onlyd difference here is
LANG=en_US.utf8

[Xavi Ivars (xavi-ivars)]

I have the same problem.

In my laptop, LANG is ca_ES.utf8@valencia

[Xavi Ivars (xavi-ivars)]

Also tested with ca_ES.utf8

Noone has solved it?

[Jefferson Andrade (joandrade)]

I have the same problem.

If I launch a Java application I can switch the input method to Anthy or Latex, but I have no accented characters, nor can get any character if I type <dead key>+<space> -- it seems that dead key are completed ignored.

If I launch the Java application as "XMODIFIERS='' <java-app-name>", than the dead key work as expected, but I can not switch the input method (so I can't use Anthy or Latex input methods). This is very frustrating since I have to type text in Portuguese, Japanese and English.

Besides the reported issues, this problems seems to affect java applications that uses Swing, but not those that use SWT.
For example, Eclipse works fine, but Netbeans is affected. I wrote a minimal swing application that is affected by the reported problem:

------
import javax.swing.JFrame;
import javax.swing.JTextField;

public class Main extends JFrame {

 public Main() {
  JTextField txtField =new JTextField();
  add(txtField);
  this.setSize(100, 100);
  setVisible(true);
 }

 public static void main(String[] args) {
  new Main();
 }
}

[Xavi Ivars (xavi-ivars)]

Any advice about how to solve this problem?

[Jefferson Andrade (joandrade)]

Not really a solution, but the input methods seems to work except for the deadkeys issue, so what I did was to install the “latn-pre (m17n)” input method in ibus, so that I can enter the accented characters via input method instead of the dead keys.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[David Gómez (dabisu)]

Yes, it's broken here too. I tested all the possible combinations. openjdk 6 and 7, even oracle jdk.

I cannot type dead keys characters, like áíéóú used in spanish. My test software is OmegaT: http://www.omegat.org

Isn't there a workaround for this problem?

[David Gómez (dabisu)]

By the way, this bug got reported in 10.04, but i'm on 11.10 and the bug is hot and running.

[Emmanuel Castro (emmanuel-castro)]

The same problem occurs with KDE based application such as VirtualBox setting application.
The same problem occurs with SCIM.
I think the bug as to be reported to the OpenJDK team.
How do KDE application handle input-methods?

[Dan Jared (danjaredg)]

The bug continues on Ubuntu 13.10 with openjdk7

[Emmanuel Castro (emmanuel-castro)]

The bug is solved on Ubuntu 13.10 with openjdk7 on my machine. Do note that I use the standard Ibus for French, Chinese, and Greek keyboards.

[David Gómez (dabisu)]

As Emmanuel says, is working on 13.10. I use ibus for Spanish (dead keys for accents) and CJK. This bug should be closed.

[dino99 (9d9)]

That version is no more supported

[Johny (juanbertinetti)]

This bug is now on Ubuntu 19.10 with openjdk-11...

[Gunnar Hjalmarsson (gunnarhj)]

Re-opening the ibus task for now.

@Johny: This is a very old bug report, and a lot has been changed since it was originally filed. Any chance you can provide some details about how to reproduce the bug on 19.10?

[Sebastien Bacher (seb128)]

The bug here is old, rather than reopening it please open a new one using 'ubuntu-bug ibus' with a detailled description of the issue and how to trigger it
