Options only work with syntactic sugar for blank nodes - not with named nodes

[smessie]

It looks like RDF with named nodes for the options in a dropdown does not work.

RDF with named nodes:

• https://solid.smessie.com/private/tests/forms/9a991c13-03f6-4bae-a435-3b32df9ddf2a.ttl
• https://formviewer.patrickhochstenbach.net/#https://solid.smessie.com/private/tests/forms/9a991c13-03f6-4bae-a435-3b32df9ddf2a.ttl
• this gives an exception Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '0') at https://github.com/danielbeeke/rdf-form/blob/7fcfe16754589127a875989bdb9ee61ce877641b/src/elements/ElementBase.ts#L102

RDF with blank nodes (syntactic sugar)

• https://solid.smessie.com/private/tests/forms/test.ttl
• https://formviewer.patrickhochstenbach.net/#https://solid.smessie.com/private/tests/forms/test.ttl
• this works

Interesting,

I think the JSONLdProxy might not nest the values.I have written a nester before: I created a gist of it:

https://gist.github.com/danielbeeke/77bcfd565322e9509588a337c204d217

It might be an option to nest the JSON before it is put into the Proxy.

I'm not sure if I understand you correctly, is that something to do on my side, or on the side of ref-form?

Anyways, in the meantime I have investigated it further and came to the conclusion that I was actually not generating rdf:List RDF, so I've changed my code and now I have RDF with rdf:List for the options.

However, I still get an error Uncaught (in promise) Error: The prefix form was not found in the form definition., but I can't seem to find the issue, is there still something wrong with my generated RDF (I can't find any mistakes) or is there a problem with rdf-form? The error is thrown here https://github.com/danielbeeke/rdf-form/blob/7fcfe16754589127a875989bdb9ee61ce877641b/src/core/FormDefinition.ts#L57

• https://solid.smessie.com/private/tests/forms/test-dropdown.ttl is the RDF which doesn't work
• https://formviewer.patrickhochstenbach.net/#https://solid.smessie.com/private/tests/forms/test-dropdown.ttl here you can see the error

When I add @prefix form: <http://rdf.danielbeeke.nl/form/form-dev.ttl#> . to my RDF, then the above error Uncaught (in promise) Error: The prefix form was not found in the form definition. is gone, but the first error Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '0') is there again.

1. Uncaught (in promise) Error: The prefix form was not found in the form definition. I think we should not check if this prefix exists, right? Because I'm not using prefixes in my RDF, I write all URI's absolute. That shouldn't make it invalid RDF.

2. Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '0') You are reading option['form:value'] here, maybe you are also expecting the predicates to be defined with prefixes?
