Read a bookmarked input value from a restore state

Server-side selectize inputs hold no options client-side, so their bookmarked value can't restore itself and must be re-applied when the choices repopulate. This reads that value from an onRestore state, trying the module's namespaced id first and falling back to the bare id.

Usage

bookmarkedInputValue(state, session, id)

Arguments

state

The restore state passed to an onRestore callback

session

The module session

id

The unqualified input id

Value

The bookmarked value, or NULL if absent
