Building table based on a pageFlowScope variable

Question

Hi,
I am trying to show a page with a popup that contains a region. Within the region, I am trying to build a table using a pageFlowScope variable as
<af:table var="row" rowBandingInterval="0" id="t4"
value="#{pageFlowScope.expression}"
binding="#{exprBean.expression}">
<af:column sortable="false" headerText="col5" id="c2">
<af:inputText value="#{row}" id="it3"/>
</af:column>
</af:table>
<af:commandButton text="Add Row" id="cb1"
partialSubmit="true"
actionListener="#{exprBean.addRow}"/>
Here "pageFlowScope.expression is a List<String> object.
The pageFlowScope.expression is being passed from the parent page to the region. The value comes up on the page which i have tried to print out in the region using <af:inputText> and this comes up fine.
I am able to get the individual items as rows. Now, I want to dynamically add a row to the list. (I initially have one row).
So, in the backing bean for this page, I have the following code for "add row"
public void addRow(ActionEvent actionEvent) {
RowKeySet rkSet = expression.getSelectedRowKeys();
if (rkSet != null) {
System.out.println("row key="+expression.getRowKey());
Iterator it = rkSet.iterator();
if (it.hasNext()) {
Object key = it.next();
expression.setRowKey(key);
else {
expression.setRowKey(new Integer(0));
List<String> newExpr = new ArrayList<String>();
newExpr.add(expression.getRowData());
newExpr.add(new String());
AdfFacesContext.getCurrentInstance().getPageFlowScope().put("expression", newExpr);
Here, I want the table to get refreshed with the new list that i put in the pageFLowScope.
But the problem here is though this gets called, the table stops with a message "Fetching Data..."
I tried with a simple partialSubmit for teh button as:
<af:commandButton text="Add Row" id="cb1"
partialSubmit="true"/>
But even in this case, the table doesn't show up the old data. It just shows "Fetching Data..."

Hi,
I have tried that too. But to no avail. I still get to the same issue.
Before long, I would like to mention that I am working with a non-bc4j component. And my jdev version is 11.1.1.3
I also built a data control which would return a list of strings. With this I bound the table in the page and after adding i refreshed the iterator. But strangely, i am still getting the same.
The table gets refreshed but the inner content doesn't come out.
I only see 'Fetching Data...' for long.
And to add more info, this page is actually a page fragment within a region that is included as a popup in another page fragment.
And the popup is as
<af:popup id="cb" contentDelivery="lazyUncached"
popupFetchListener="#{backingBeanScope.formulaBuilderBackingBean2.putConditionInPFS}">
<af:dialog id="d2">
<af:region value="#{bindings.CBuilder1.regionModel}"
id="r1"/>
</af:dialog>
<af:setPropertyListener from="#{requestScope.expression}"
to="#{pageFlowScope.expression}"
type="popupFetch"/>
</af:popup>
And the page definition for the corresponding task flow is as:
<taskFlow id="CBuilder1"
taskFlowId="/WEB-INF/pages/oracle/epm/calcmgr/common/cbuilder/CBuilder.xml#CBuilder"
activation="deferred"
xmlns="http://xmlns.oracle.com/adf/controller/binding"
Refresh="ifNeeded">
<parameters>
<parameter id="expression" value="#{pageFlowScope.expression}" xmlns="http://xmlns.oracle.com/adfm/uimodel"/>
</parameters>
</taskFlow>
Thanks,
Pawan.
