Error FND_WF_IN_PROGRESS_FOR_TXN while invoking workflow via OA Framework

Question

Hello,
I am invoking a workflow from OA Framework page.
Basically I am creating an entity and at the end of the entity creation, I am triggering workflow for its approval. It works first time and now I create a new entity and
try to trigger approval, I get this error.
Error MESSAGE_NAME is FND_WF_IN_PROGRESS_FOR_TXN and Text is (from FND_NEW_MESSAGES table)
Workflow with item type (&ITEMTYPE) and item key (&ITEMKEY) is in progress. Abort existing workflow before launching a new process for this transaction.
For some reason, exception shows item key, of the workflow which got successfully triggered earlier.
So second time, when I try to trigger workflow Item key used is Item key: XXIFMS_NO_100072
but exception is for previous key
oracle.apps.fnd.framework.OAException: Application: FND, Message Name: FND_WF_IN_PROGRESS_FOR_TXN. Tokens: ITEMTYPE = XXIFMSSA; ITEMKEY = XXIFMS_NO_100071; at oracle.apps.fnd.framework.webui.OANavigation.initialize(OANavigation.java:233) at oracle.apps.fnd.framework.webui.OANavigation.createProcess
Here is my code to generate, item key (based on a sequence)
String serialNumber = "XXIFMS_NO_";
String wfItemKey = serialNumber + tr.getSequenceValue("POR_REQ_NUMBER_S").toString();Error seems to suggest that within one transaction only one workflow can be launched.
Is there a way to explicitly start a new transaction using AM?
regards, Yora

The error comes from the initialize method in the OANavigation class. You can either extend the class and override any needed methods, or add code to the AM to set up the Workflow context so that you can use the API w/o the Oracle Applications wrapper. It looks like the Wrapper was made available mainly for using WF for the pages in OA framework.
Instead of creating a new class, I added the code to my application module. Afterwards I can submit multiple workflows. An overview of what I did is:
1. Add required imports to AMimpl
2. Add two methods to AMimpl: setUpWF, releaseWFJdbcConnection, submitToWorkflow
3. Call the methods to submit to workflow in the apply method before calling the commit method.
4. Call the apply method as normal from the controller.

Oracle is removing some text. For instance areas with [i] are being removed. If reposting does not fix the issue, then note in the example code you need to recompile and you may need to add the array indexes manually.
***** NOte Oracle's Editor is remvoing text from the code I posted. I don't have time to troubleshoot this. The ARRAY Indicators are being removed. Make sure you compile and manually put back the ARRAY INDEXES as needed in the sample code.*****************
