Language metadata launchs JavaScript error

Software Support
1

Hi,
OJS 3.2.1-1 (upgraded from 3.1.1-4)
LAMP

When editing the Language field metadata in a submission I’m getting a duplicated entry. One seems accepted by the system, and the other remains in “still-editing” mode, as shown below.
metadato-idioma-carga-duplicado

By viewing Chrome’s Console I see the following when entering the first character of the language

TypeError: this.suggestions.filter is not a function

Hi @jascanio,

Is there anything related to this in the PHP error log?

Hi @asmecher,

I’ve been digging into the error log and found no relevant entries.

What I see in the Chrome’s console is that the JavaScript filteredSuggestions (lib build.js) the this.suggestions is an object instead of an array (unlinke disciplines or agencies) and launches a exception “filter is not a function”.

We have found that the languages API returns the following JSON

Hi again @asmecher,

Issue update.

The only way we have found to solve the issue is to return from the associative array $languageNames, the values part making an array_values($languageNames) in line 102 of file
lib/pkp/api/v1/vocabs/PKPVocabHandler.inc.php

This way we have solved the problem with language metadata, although we’ve had to hack the code, which we are sure it is not the path to the solution to our problem.

Hope this helps you to figure out what is wrong with our OJS instance. Maybe something went wrong with our upgrade procedure. We don’t know.

Thanks in advance for your help.

Regards,
Juan
