In an ftd function body, you can use the tuple variant of
`ftd.submit_form` method. This does not require you to have a
`ftd.string-field` instance.
```ftd
ftd.submit_form(
action_url,
("concept-url", concept_url),
("status", status, error)
)
```
The third element of the tuple is a mutable variable defined as:
```ftd
-- optional string $status-error:
```
Note that the use of `optional` is necessary as using just the `string`
type would issue warning and will not get updated from js.
