Problem translating content inside a container element.

[PaDa19]

Hello,

I have created a mask element that uses the Content field. I used the field inside a container element.
I can localize the mask element but not the content that I put into the Content field. All content elements in the Content field are greyed out in the translated Mask element.
The button "Localize all records" is active but nothing happens when I click it.

If I look at the network traffic I see that the following ajax call is made:
https://[mydomain]/typo3/ajax/record/inline/synchronizelocalize?token=9234e....

Response:
{"data":"","stylesheetFiles":[],"scriptItems":[],"compilerInput":{"localize":[],"delete":[]}}

I have created a new content element in the second language manualy and selected the parent element in the dropdown. That looks correct in the backend but the frontend still shows the content of the first language.

I use TYPO3 12.4.1 with Mask 8.1.5 and Container elements 2.2.2

All works well if I use the mask element without a container.
ATM I am using this workaround: I create the element outside the container and translate it. After that I drag it into the container.

Can anyone else confirm this issue?

Thanks,
Patrick.

looks like a EXT:mask issue? can you describe the issue in an TYPO3/container Vanilla Instance? (because EXT:container knows nothing about mask)
