Dots in attribute names handled incorrectly in data (Angular)

[grunci]

Describe the bug

If I have a property name in the JSON Schema which contains a dot (.) character, JSONForms creates a sub-object in the data and splits the attribute name instead of using the original attribute name.
Example:
If the attribute name is "foo.bar" according to the JSON Schema, the generated data will look like this:

{
"foo": {
   "bar":"some data" 
   }
}

This is problematic, because the generated data will never be valid against the schema

Expected behavior

If the JSON Schema attribute name contains a dot, it should not be handled as a sub-object separator in the generated data.

Steps to reproduce the issue

1. Create a JSON Schema, where one of the attribute names contains a dot character.
2. Load that schema into JSON Forms (Angular)
3. Fill in the form
4. Check the generated value. It contains the above mentioned sub-object structure.

Hi @grunci,

Dots in names are currently not supported as we are using dot separated data paths. The good news is that we are working on it. However this is a major breaking change for all adopters with custom renderers, so this will only be merged for JSON Forms 4.0 which will likely not be released before 2026.
