These breaks use cases where we **do want** to store the Long values as Long and not as Ints (for example test cases that use the same generated mock data to store in the database and to test against).\r\n\r\n### Proposed solution\r\n\r\nHave an annotation that tells ObjectBox to store Long values as Long.\r\n\r\n### Alternatives\r\n\r\nTried using a `PropertyConverter` however this breaks for the mapping I've provided.\r\n\r\n### Additional context\r\n\r\nKotlin\r\nAndroid\r\n","author":{"url":"https://github.com/alghe-global","@type":"Person","name":"alghe-global"},"datePublished":"2024-07-02T07:06:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/1181/objectbox-java/issues/1181"}
