Circular Structures

[Fannon]

Hello there,

I've found one may-be-issue: If the fetched JSON Schema contains circular references, the schema is not parsed and no error message is thrown.

I think it is usually better to avoid circular structures in forms since you could nest into eternity. But there are cases where this is interesting, for example a Person who can know a Person. This leads to graph data structures, but a lot of our data is in fact a graph.

Greets,
Simon

I agree that support for recursive schemas would be useful, but it would require a major rewrite of a lot of the core code. Schemas go through a pre-processing step that expands out $ref, extends, oneOf, etc.. Recursive schemas cause an infinite loop. The rest of the code depends on this pre-processing step and fixing it would be a pretty big undertaking.
