Translation Manager – Custom Value Mapper for Limbo.Umbraco.Tables

NicoM77 · July 29, 2025, 9:58am

Hi everyone

I’m currently trying to create a custom value mapper for the Limbo.Umbraco.Tables package, but I’m running into some issues and haven’t had much success so far.

From what I understand, I should be using the approach described here:

However, I’m having trouble understanding it, and I can’t seem to get it working properly.

Has anyone here already done something similar and would be willing to share their translation_mapping.config file? Or perhaps just point me in the right direction on how to set this up?

Thank you in advance for your support!

Best regards

Hi,

I don’t think you can use the config way on this property editor because its storing the content inside arrays inside arrays and the config mapper really can just cope with manipulating a simple json object to get the values out of it.

however. it can be done with a bit of custom code - so i’ve knocked up a LimboTables property editor (see below) and this should do it.

LimboTablesMapper.cs

using Jumoo.TranslationManager.Core;
using Jumoo.TranslationManager.Core.Extensions;
using Jumoo.TranslationManager.Core.Models;
using Jumoo.TranslationManager.Core.ValueMappers;

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

using Umbraco.Cms.Core.Services;

This file has been truncated. show original

This is for Umbraco v13 (hence its still using NewtonSoft) -I don’t think Limbo.Tables is out for v16 anyway so shouldn’t be an issue ?
