I'm getting a strange error message: ```Caused by...

I'm getting a strange error message:

Caused by: java.lang.IllegalStateException: Can't init value outside the transaction

When using exposed in the spring integration flow handler. Everything works...

The function that throws the exception:

@Suppress("UNCHECKED_CAST")
    override fun getValue(thisRef: Any?, property: KProperty<*>): T? {
        val currentOrNullTransaction = TransactionManager.currentOrNull()
        return currentOrNullTransaction?.getUserData(key)
            ?: init?.let {
                val value = currentOrNullTransaction?.it() ?: error("Can't init value outside the transaction")
                currentOrNullTransaction.putUserData(key, value)
                value
            }
    }

Where the property is an dao.EntityCache but I'm not even using DAO classes. Just the DSL. Is some entity cache used when just using the DSL?

[Gustav Elmgren]

All this is triggered by some EntityLifecycleInterceptor , but (again) I do not have any DAO classes. Why would this be added as global inteceptor?

[Gustav Elmgren]

Also:

TransactionSynchronizationManager.isActualTransactionActive()

return true.

Return whether there currently is an actual transaction active. This indicates whether the current thread is associated with an actual transaction rather than just with active transaction synchronization.

So I guess:

1. I don't understand why there is a global interceptor that does something with the dao.EntityCache
2. Why does spring says that there is a current active transaction in the thread, but exposed says otherwise?

This is out of my depth, but... are you sure the Spring and Exposed transactions are compatible?
