PPR bug when multiple regions share same iterator ?

Question

Hi,
I have a page with a table binded to iteractor X.
This page has a region binded to a bounded taskflow Y.
Taskflow Y has a fragmented view with a form Z binded to iterator X.
Form Z has a create button which fires the CreateInsert operation on the iterator X and has immediate = false because I want to execute validations on the current record
Taskflow Y has the <data-control-scope> set to shared.
On both views pagedefs the iterator X has the property ChangeEventPolicy="ppr"
User case 1: If table is not empty (iteractor X has a current row value), when I press the create button, the form Z refreshs with a new record and the table is refreshed with an empty record as well.
Use case 2: However, if the table is empty (iteractor X has no current row value), when I press the create button, the form Z refreshs with a new record and the table is refreshed with an empty record as well but, somehow, the page fires another page refresh which causes the form Z to process validations and show errors on mandatory fields.
Notes:
- I cannot use PartialTriggers because the fragment region does have references to table components on the main page
- I could use contextual events however PPR on iterator X and sharing data controls between the region taskflow and calling page should be enough because use case 1 works.
Any ideias ?
Thank you in advance.

Thanks Frank
Yes, that was one of the first things I did but somehow the region does not know its contents were refreshed in order to fire partial triggers. Here is the source code:
Of the table:
<af:table value="#{bindings.EbaErpSuppliersInvoices.collectionModel}" var="row"
rows="#{bindings.EbaErpSuppliersInvoices.rangeSize}"
emptyText="#{bindings.EbaErpSuppliersInvoices.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.EbaErpSuppliersInvoices.rangeSize}"
rowBandingInterval="0"
filterModel="#{bindings.EbaErpSuppliersInvoicesQuery.queryDescriptor}"
queryListener="#{bindings.EbaErpSuppliersInvoicesQuery.processQuery}"
filterVisible="true" varStatus="vs"
selectedRowKeys="#{bindings.EbaErpSuppliersInvoices.collectionModel.selectedRow}"
selectionListener="#{bindings.EbaErpSuppliersInvoices.collectionModel.makeCurrent}"
rowSelection="single" id="t1"
binding="#{backingBeanScope.backing_Views_Erp_SuppliersInvoicesList.t1}" displayRow="selected">
</af:table>
Of the region:
<af:region value="#{bindings.supplierinvoiceformbtf1.regionModel}" id="r1" binding="#{backingBeanScope.backing_Views_Erp_SuppliersInvoicesList.r1}" partialTriggers="::pc1:t1"/>
Of the btf:
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<task-flow-definition id="supplier-invoice-form-btf">

<shared/>
</data-control-scope>
<managed-bean id="__8">
