[TYPO3-mvc] How do I set up sys_language_uid in controller?

[Jakub Zembala]

Hello Dmitry,
You can try to add 
'default' => -1,
in Your TCA language field ($TCA['tx_yourext_domain_model_yourmodel']['columns']['sys_language_uid']['config']['default'] = -1;), it works fine if You create it in BE using normal "add element" in List View, but if You want to create It automaticly, I can't help. All i know is that You must mapping sys_language_uid in Your "ext_typoscript_setup" like this: 
TYPO3\Gcmodels\Domain\Model\Portfolio {
                mapping {
                    columns.sys_language_uid.mapOnProperty = sysLanguageUid
                }
            }
and create property in Model Class with setters and getters. So if this solution doesn't work properly, I hope that someone else can help You.
