Additional Information

This seems to be caused by the use of the enum restriction in the json schema for the component.
We are assuming that the type of the enum content is string, but that is actually a false assumption. In this case the type is number.
It is unfortunate that the json schema does not contain the explicit type in the cases where enum is used - this would make it much clearer for us what type we are working with. In our JSONSchema conversion script, we assume that the type for a property with enums is string, but this is not correct.

We need to:

• update the script, to check the value of the first item of the enum array, and set either string or number type based on that.
• Update the EditNumberValue component to act like the EditStringValue component when there is an enum set present (i.e. render a select rather than an input field).
