Text change event timeout for select fields


in our forms we use Select fields for properties that refer to database entries. The user types a search string into the Select field, the Select’s container searches for matching entries in the database and the Select populates its options with the matching entries returned by the container.

Unfortunately I didn’t find a way to set a ‘text change event timeout’ on the Select field.This leads to many unnecessary events and database searches. Let’s say the user wants to search for entries that start with ‘abc’, so the user types in ‘abc’. As soon as he typed the first character ‘a’, an event is already triggered and sent to the server and the container already performs a database query with the search string ‘a’.

Is there a possibility to configure an event timeout for Select fields as it can be done for TextFields (see TextField.setTextChangeTimeout(…)) ?

Thanks for you help!
