Panels/i18n: wrong/no node content displayed if no translation exists

Actually, the panel previews show the wrong nodes as well. When I first add the node content, the auto-complete finds and shows the correct NID and node title.

Could this be related to the i18 module at all? The nodes in question that don't show up correctly are Japanese language nodes.

Here is a little bit more specific information. When I export one of the panel pages with an included node context, the script (see below) shows the correct NID (5529) for the node that I want to display. However, when I actually load the page, the panel instead displays NID 1387.

I will try to save this script and see if I can get the appropriate variables to print out (my first time debugging php so I don't know if I can do it or not) to try to figure out where it goes wrong... Can anyone help?

I made module using Panels Exporter. The module showed up and I was able to activate it. I changed the path so that I would be able to distinguish the module-generated panel page from the panels-generated panel page from which it was exported. However, the new path cannot be found. Is there something else I need to do to get this module to actually make the page?

Here is the script for my new module panelnodetest.module

<?php

function panelnodetest_default_panel_pages() {
$page = new stdClass();
$page->pid = 'new';
$page->name = 'test';
$page->title = 'test';

);
$display = new panels_display();
$display->did = 'new';
$display->layout = 'onecol';
$display->content = array();
$display->panels = array();
$pane = new stdClass();

$pane->shown = '1';
$display->content['new-1'] = $pane;
$display->panels['middle'][0] = 'new-1';
$page->display = $display;
$page->displays = array();
$pages['test'] = $page;

return $pages;
}

OK...now I get my new module to generate the page but it still displays the wrong node. I just don't understand this since the NID is hard-coded into the module. So the Panels module is not using the NID stored in

$page->contexts['0'] = array (
'name' => 'node',
'id' => 1,
'identifier' => 'NJ ACIM class',
'keyword' => 'node',
'context_settings' => array (
'node' => '5529',
'nid' => '5529',)
);

to generate the displayed node. or some operation is being performed on the value to alter it. Where do I go looking for this? Is this a bug?

The file contexts/node.inc in version 5.x-2.0-rc1a has some logic in lines 45-57 that checks to see if the translation module is active and, if so, looks up the NID for the translation of the node in question. However, if there is no translation then the node's NID gets replaced with another NID that is, as far as I can tell, random, or at least wrong. Simply adding another IF statement to check to see if $translation is not empty before doing the translated NID lookup and storing seems to fix this problem. If one's site has more than two languages (mine has only two), I am not sure if this is enough to get it working.

This is my very first time making a patch so please check well and forgive if I've made some fundamental mistake!

Ah, now I have found that my patch does not work if there is more than one node context. $nid and $translation are arrays and so it is presumably necessary to cycle through the arrays and make sure that if there are any NULL values for translations, that no arbitrary nid is inserted for them. I have to learn a little more about what kind of arrays these are and how they work, and then I'll try to submit a new patch...

I haven't figured it out yet. I have been trying to write various loops to cycle through the NID values, but I don't clearly understand how the data structure containing the NIDs is set up. I'm a bit new to this. I'll try to look at it more but I'm hoping somewhere more familiar with the code will take a look at it. I do think it will be easy enough to fix once the correct knowledge of the array or object or whatever it is, is in hand.

Sun: In this instance, I correctly filed the issue against Panels version 5.x-2.0-rc1a. The problem relates to its interaction with i18 module, for which there most certainly is a 5.x version, and not Translation module.

The naming conventions of the modules providing multi-lingual support could be more clear, but there is a translation folder (module) WITHIN (i.e. that comes with) the 5.x-2 Internationalization module. Why the module is called Internationalization but the file is called i18n is unclear to me. You will see it if you download it here:
http://ftp.drupal.org/files/projects/i18n-5.x-2.4.tar.gz

I presume that THIS Translation module is what the code is interacting with...
