fix(ui): resolve a composite field's id to its input, not its wrapper

[joshbrewster42]

Problem

Closes #937.

location, locationbased, png and typeahead each return a wrapper <div> from their helper, and each helper has already set schema_<id> and data-config-id on the control inside it. createFormFields then sets both on the wrapper too, so two elements answer to the same identity.

getElementById and querySelector return the first match in document order, which is the wrapper, and a <div> has no value. Two things break:

1. A schema.Generated sourced from one of these fields is handed param: undefined. Its handler returns nothing and the generated fields never render. The if (!sourceField) guard in createGeneratedField does not fire either, because the wrapper is a real element, so nothing appears in the console.
2. importConfig looks the field up by [data-config-id] and assigns to .value. That lands on the wrapper and is silently discarded, so importing a settings file does not restore these fields.

I hit the first one with a custom app: a schema.Location feeding a schema.Generated that returns stop pickers. The dropdowns never appeared, with nothing in the console or the server log.

Fix

Only stamp the wrapper when it does not already contain the control:

const inner = inputElement.querySelector
  ? inputElement.querySelector('[data-config-id="' + field.id + '"]')
  : null;
if (!inner) {
    inputElement.id = inputId;
    inputElement.dataset.configId = field.id;
}

Structural rather than a list of type names, so a new composite field type is covered without anyone remembering to add it. The event listener below is left attached to the wrapper, since handleConfigUpdate reads event.target, which is the inner control in either case.

Testing

Pulled createFormFields and createGeneratedFormFields out of the template and ran them under jsdom, with the handler fetch stubbed, building a schema.Location plus a schema.Generated sourced from it.

On main: two elements with id="schema_home" (DIV, INPUT), getElementById returns the DIV, .value is undefined, [data-config-id] also returns the DIV, the handler receives an empty param, zero generated rows.

With this change: one element, getElementById returns the INPUT carrying the saved location, [data-config-id] returns the INPUT, the handler receives a populated param, both generated rows render.

Also checked text, toggle and dropdown still get their id and data-config-id on the control itself. Those pass identically before and after.

Summary by CodeRabbit

• Bug Fixes
  • Fixed configuration forms that use wrapped fields so each field is identified only once. Fields without a matching nested element continue to work as before, and field identifiers containing quotation marks no longer cause matching errors.

📝 Walkthrough

Walkthrough

createFormFields checks whether a returned wrapper contains a descendant with the field’s data-config-id. It assigns the field ID and dataset to the wrapper only when no matching descendant exists.

Changes

Field identity handling

Layer / File(s)	Summary
Prevent duplicate field identities web/templates/manager/configapp.html	createFormFields leaves the wrapper’s ID and dataset unset when a descendant already has the field’s data-config-id. It checks descendants by iteration, avoiding selector parsing errors for field IDs that contain quotes.

Before / after behavior

• observed — Modified behavior in web/templates/manager/configapp.html: createFormFields now searches a returned wrapper’s descendants for a matching data-config-id and only assigns the field ID and dataset to the returned element if none is found. This replaces unconditional assignment, preventing wrapper and inner control from sharing the same identity; iterating candidates also avoids selector errors for quoted field IDs.

- Around line 959-971: Update the inner-control lookup in createFormFields to
avoid interpolating field.id into a CSS selector, since valid IDs containing
quotes can make querySelector throw. Find the matching descendant by comparing
its data-config-id value directly with field.id, preserving the existing wrapper
fallback when no match exists.

Good catch, and it is worse than minor: the selector throws inside createFormFields, so every field after the offending one fails to render too.

Reproduced it with a schema.Location whose id is api"key:

SyntaxError: Invalid selector [data-config-id="api"key"]

and the plain text field declared after it never appeared.

Fixed by walking the descendants and comparing dataset.configId rather than building a selector at all, which sidesteps escaping entirely. Added that id to the jsdom checks: form creation no longer throws and later fields still render.
