empty properties in schema

[gioppoluca]

I'm generating the properties of the schema dynamically and there could be the case of no fields needed for some use cases.
In this event the form is like:

[
  "*",
  {
    "type": "submit",
    "title": "OK"
  }
]

While the schema is:

{
  "type": "object",
  "title": "Types",
  "properties": {}
}

I'm expecting to have an empty form with just the submit button instead I get nothing.
Any hint?
Thanks

I'm facing the very same problem. During re-rendering a form due to schema changes, the form stays the same if properties is an empty array. But if there is at least one single property, it replaces the old form.

You may fix this by removing this line, but then you're receiving the following set of errors, first one in this line

If you find the code && Object.keys(schema.properties).length > 0 and remove it, then add {"key":"submit", "type": "hidden"} to your form it would work. I'll look into something more permanent though.

This should be working in the alpha now :)
