Warning: Unable to use English input method

[skyper]

What steps will reproduce the problem? ¶

Do not really know.
I am using an external keyboard with German layout and default 105+ nodeadkeys German setting.
JOSM language setting is unchanged (system defaults) and locale is LANG=en_US.utf8 with LANGUAGE= unset.

What is the expected result? ¶

No repeating warning and info messages in the console.

What happens instead? ¶

Console is spawned with messages:

Please provide any additional information below. Attach a screenshot if possible. ¶

Can not really tell when it started but not that long ago. Might have some more time after the weekend to try different revisions and different keyboards.

Ok, I have tested with a different keyboard and back to r14620 without any different behavior.

I figured out, that it is triggered by the "Add Value" dialog with the context menu option "Use English language for tag by default" enabled. It is kind of strange as I would remember if I had gotten these messages on the console for month now. Maybe, I enabled this option by accident or some underlying software did change.

This is really environment specific. If Java cannot use English input for whatever reason, JOSM can do nothing about it.

[skyper]

Why is JOSM expecting an English keyboard setting and even trying to change the setting/layout if I enable "Use English language for tag by default"? This seems to be wrong.

[Don-vip]

If you enable this option, JOSM tries to setup English input method but restores the previous one in case of failure:

    /**
     * If the locale is fixed, English keyboard layout will be used by default for this combobox
     * all other components can still have different keyboard layout selected
     * @param f fixed locale
     */
    public void setFixedLocale(boolean f) {
        useFixedLocale = f;
        if (useFixedLocale) {
            Locale oldLocale = privateInputContext.getLocale();
            Logging.info("Using English input method");
            if (!privateInputContext.selectInputMethod(new Locale("en", "US"))) {
                // Unable to use English keyboard layout, disable the feature
                Logging.warn("Unable to use English input method");
                useFixedLocale = false;
                if (oldLocale != null) {
                    Logging.info("Restoring input method to " + oldLocale);
                    if (!privateInputContext.selectInputMethod(oldLocale)) {
                        Logging.warn("Unable to restore input method to " + oldLocale);
                    }
                }
            }
        }
    }

This is perfectly fine. The problem is that your setup forbids to use English input, I don't know why.

Ok, then the description is off as there is no word about input method.

Does changing the input method only for certain windows or combo boxes work with Wayland?

[Don-vip]

It's here since r5704 and it seems to do exactly what is meant by the UI. If you find it unclear, please feel free to update the wiki.

[skyper]

If was referring to Use English language for tag by default which, in my eyes, should be changed to Use English input method for tag by default or Use English keyboard layout for tag by default. As written above, my whole system is using English but with a German keyboard and German keyboard layout.

I will try to better document on the wiki but the description in the context menu is misinterpretable and, at least, for languages with Latin letters quite strange.

[skyper]

Can anyone confirm that this setting is working on Linux, especially, with Xwayland in use?
