Bug: Culture variant Block does not act correct without any varying properties

[nhudinh0309]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

15.0.0-rc4

Bug summary

In content that includes both invariant and variant blocks, the data in the invariant block is not saved correctly in different languages.

Specifics

No response

Steps to reproduce

1. Create an element type with "Vary by culture" enable for all properties (ex. ElementForBlock)
2. Create other element type with "Vary by culture" enable for all properties (ex. ElementForBlockINV)
3. Create a document type with Block List property that includes ElementForBlock and ElementForBlockINV
4. Create a content with the Block List
5. Add one variant block and on invariant block

Expected result / actual result

The data in the 2 blocks should be saved correctly. Currently the data in the invariant block is not saved correctly in different languages

Hi @nhudinh0309

Thanks,

The invariant Block you described must be an Element that Varies by Culture, but does not have any varying properties. This case I'm able to replicate.

It turns out the server changes the expose entry, most likely because of no properties varying on this Element.

this the my request:

and response from the server:

So with that it turns out to be a backend bug. But notice the very specific case of having varying element without any varying properties.
