yes and yes.
I would call it cached and if the TV is empty, it will not output anything

Hi @bruno17 , I have followed the tutorial above.
Every works so far, but I am getting an error in the logs:
ERROR @ …/core/xpdo/om/xpdoobject.class.php : 811) modTemplateVar: Attempt to set NOT NULL field type to NULL
Do you have any idea where this may come from ?
[{
"caption": "Image",
"fields": [{
"field": "placeholder",
"caption": "Placeholder",
"inputTV": "placeholderTV"
},
{
"field": "title",
"caption": "Title",
"description": "Title for the image."
},
{
"field": "alt",
"caption": "Alt",
"description": "Alt for the image."
},
{
"field": "caption",
"caption": "Caption",
"inputTV": "",
"inputTVtype": "listbox",
"inputOptionValues": "no==0||yes==1"
},
{
"field": "image",
"caption": "Image",
"inputTV": "imageTV"
}
]
}]

"inputTV": "imageTV"
}
]
}]
The chunck is below:
I can’t think, how this could be related to the MIGX setup.
Seems something is trying to save NULL into a not NULL field type at the modTemplateVar - table.
When exactly does it happen?
I think it’s my fault 
, I left "inputTV": "" in the code. I removed, and I believe it fixed the issue.
P.S. I celebrated too soon, the error still there.
