Android Room Observer：关系数据更新未正确显示

Question

我有一个如下的关系数据结构

Entry.kt

@Entity(tableName = "entries")
data class Entry(
    @ColumnInfo(name = "entry_id") @PrimaryKey(autoGenerate = true) val entryID: Long,
    @ColumnInfo(name = "time_stamp") val timeStamp: Timestamp
)

Feeling.kt

@Entity(tableName = "feelings")
data class Feeling(
    @ColumnInfo(name = "feeling_id") @PrimaryKey(autoGenerate = true) val feelingID: Int,
    val feeling: String,
    val color: Int
)

Subentry.kt

@Entity(tableName = "sub_entries",indices = [Index("feeling_id")])
data class SubEntry(
    @ColumnInfo(name = "sub_entry_id") @PrimaryKey(autoGenerate = true) val subEntryID: Long,
    @ColumnInfo(name = "entry_id") var entryID: Long,
    @ColumnInfo(name = "feeling_id") val feelingID: Int,
    val intensity: Int
)

以及连接三者的道场

EntryWithSubEntriesAndFeelings.kt

data class EntryWithSubEntriesAndFeelings(
    @Embedded val entry: Entry,
    @Relation(
        parentColumn = "entry_id",
        entityColumn = "entry_id"
    )
    val subEntries: List<SubEntry>,
    @Relation(
        parentColumn = "entry_id",
        entityColumn = "feeling_id",
        associateBy = Junction(SubEntry::class)
    )
    val feelings: List<Feeling>
)

现在有了预填充的感觉数据库，一切正常。但我目前正在添加插入自定义感觉的功能。这些和相应的子条目最终正确地出现在子条目数据库中（我从虚拟设备复制了数据库文件并手动检查了它们）。但是由于某种原因，新的感觉并没有传递给观察者和适配器，因此它没有与其他子条目一起显示。

感谢任何提示！ :)

事实证明，我的代码中仍然有一些对初始列表的硬编码引用，这阻止了新感觉的显示。
