Function: createInstance()
createInstance(
definition,id,props?):ComponentInstance
Create a new instance with insertion-time defaults:
materialises field.default values only — content-keyed fields stay unset
until a merchant overrides them. Throws on programmer errors (empty id,
unknown keys, wrong-typed values, a required field with nothing to fill
it); the storefront never calls this. A required field with a contentKey
is filled from the content pack at render, so it may be left unset here.
Authored defaults are validated exactly like provided values: a default that
fails its field's rules (out-of-range number, off-list select option) is an
authoring bug, and validateThemeDefinition reports it at assembly time —
baking it into an instance silently here would let the writer and the reader
disagree.
