Repackaging Form Not Working

Problem/Motivation

The repackage / rebuild language list form at admin/l10n_server/packager is always calling the submit function for the button "Rebuild language list" no matter which button you click.

The problem here is that the #submit values for bot buttons under project translations get ignored and therefore there's no way to repackage or mark projects for repackaging from the interface.

Proposed resolution

(description of the proposed solution, the rationale behind it, and workarounds for people who cannot use the patch)
It seems that the array_merge at l10n_packager_admin_repackage_page() is meesing up the form. Maybe we could change that to two different forms or fix it so it doesn't beak.

Although another bug arises when the button works and l10n_packager_admin_projects_form_submit gets called, repackage now will fail with:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /?q=batch&id=4&op=do StatusText: error ResponseText: PDOException: SQLSTATE[HY000]: General error: 1364 Field 'fid' doesn't have a default value: INSERT INTO {l10n_packager_file} (rid, language, checked, sid_count) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3); Array ( [:db_insert_placeholder_0] => 3 [:db_insert_placeholder_1] => es [:db_insert_placeholder_2] => 1335481282 [:db_insert_placeholder_3] => 5 ) in drupal_write_record() (line 6975 of /home/checkout/l10n_server/includes/common.inc).
Although that shuld probably be filled as a different issue.

Remaining tasks

Writing a patch, testing it, reviewing it and committing it.

User interface changes

It should look the same but might get changed to two different forms.

API changes

none.
