Creating rows through entity variable makes updates not possible

Question

I went through the following basic scenario of using entity variables in my BPEL process running in SOA Suite 11.1.1.3.0.
We have an ADF business component (SDO) deployed in the SOA environment which represents an updatable View object with all available methods exposed in the service interface. The primary key column in the underlying entity object is filled from an Oracle sequence when the entity is created.
When triying to make use of this SDO through entity variables later on I encounted the following strange behavior.
The Create Entity activity being placed alone in the BPEL can successfully create an entity, no problem with that. The transaction gets committed and a new row is inserted in the database. But trying to make this simplest scenario a bit more complex fails... Indeed let's put a simple Assign activity after the Create Entity activity and change some field's value. Running the process results in a fault being thrown with this in the stack trace :
Caused by: oracle.jbo.service.errors.ServiceException: JBO-25020: View row with key oracle.jbo.Key[2942 ] is not found in Ta
xOfficeView1.

This basically means that Create Entity succeeded getting the primary key value from the sequence and prepared the row for creation but a posterior update could not locate it in the view object. Probably the runtime was trying to get the row from the database but since the transaction had not committed yet it did not find the row.
I've been trying with no success to get any working samples in the Oracle documentation or any traces in Google about using entity variables to create and update rows in the same BPEL. The only references I found were about binding to existing rows and then updating them. I tried this out, it works but I need to CREATE and UPDATE rows!
Has anyone run into this issue already?

Hello.
Yes, I've met this issue.
The root of the issue in your Entity Object. I suppose that Pk is auto generated by sequence in your database. You should open your EO, then chose Attributes, then double click on primary key attribute. The screen named "Edit Attribute: <your primary key>" opened. Check the box Refresh After "Insert" in the bottom right corner of this screen. It means that after inserting of a new Pk in your table this one will be re-read back to VO and therefore you will be able to update the Entity variable. Clear all, rebuild, redeploy, enjoy.
You should to do it for all EOs you are going to use for creating Entity variables.
