ERROR

No errors generated when deploying the composite

The following error message appears in the logs :

[] [soa_server] [ERROR] [] [oracle.soa.adapter.db.inbound] [tid: DaemonWorkThread: '11' of WorkManager: 'default_Adapters'] [userId: weblogic] [ecid: ] [APP: soa-infra] [partition-name: DOMAIN] [tenant-name: GLOBAL] [composite_name:name] [composite_version: 1.0] [service_name: name] Encountered a fatal exception while polling. Will continue polling but with minimal logging. Please investigate the fault and manually stop polling from the console if in development and this appears to be a modeling mistake. BINDING.JCA-11624[[
DBActivationSpec Polling Exception.
Query name: [<name>], Descriptor name: [PoolDatabase.XxgSoaStgHdr]. Polling the database for events failed on this iteration.
Caused by java.lang.ClassCastException.
This exception is considered not retriable, likely due to a modelling mistake. This polling process will shut down, unless the fault is related to processing a particular row, in which case polling will continue but the row will be rejected (faulted).

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Create composite and add Database Adapter to poll records in a database
2. Select "Update an External Sequencing Table on a Different Database"
3. Records are not updated in the External Sequencing Table on a Different Database

If "Update a Sequencing Table" is selected, then the sequencing table is updated. The issue is only with External Sequencing Table on a Different Database

Changes

 Select External Sequencing Table on a Different Database
