I have tested this item unsuccessfully on 8a773ec

Applied patch in current 3.5.0beta staging.

Added field countrylist in
/administrator/components/com_content/models/forms/article.xml
inside block

<fields name="attribs" label="COM_CONTENT_ATTRIBS_FIELDSET_LABEL">

<field
name="country"
type="countrylist"
label="countrylist"
description="countrylist" />

Opened article > Tabulator Options.

I see the field but all language placeholders are untranslated (e.g. JCOUNTRY_ARUBA)

The language strings definitively need translations provided for en-GB.
ALso, is there a reason you use alpha-3 codes and not the alpha-2 ones? In Joomla we use two letter codes for our language-country codes (eg "en-GB"). I think we should follow that where possible.

This PR has received new commits.

CC: @bertmert

I changed
ISO 3166 alpha-3 codes
to
ISO 3166 alpha-2 codes

I will add translations in en-GB.ini

I have tested this item successfully on 6f2883b

Since translations are in different branch, I still see JCOUNTRY_ARUBA etc. @yannis79 could you merge your patch-2 into patch-1?

Sorry, meant to choose unsucessfully, can I somehow change test result?

You cant but I can ;)

@renekorss, I would merge them but I really don't know how!

@yannis79 What tool are you using? On command line it should look like this:

git checkout patch-1
git merge patch-2
git push

In the current state this is not ready. Please update the PR as above or if you have issues please ask. If not this will have to be closed in a few weeks.

As stated above this cannot be merged at this time and as there has been no update I am closing it. If it is updated as requested it can always be reopened
