In a popup the tree table data is not getting displayed properly

Question

Hi,
I have a taskflow which contains a tree table within a panelStetchLayout. Following is the taskflow code :
<af:panelStretchLayout id="SecurityAdminManageRoles" bottomHeight="0" topHeight="auto" inlineStyle="width:725px;height:400px;">
<f:facet name="center">
<af:treeTable value="#{bindings.WebCenterSecurityDCPermission.treeModel}" var="node" expandAllEnabled="true" fetchSize="150" verticalGridVisible="false" horizontalGridVisible="true" columnSelection="none" rowBandingInterval="0" columnStretching="last" contentDelivery="immediate" summary="#{uib_o_w_w_r_WebCenter.SECURITY_PERMISSIONS}" disclosedRowKeys="#{webcenterAdminSecurityBean.disclosedRowKeySet}" inlineStyle="border:none" binding="#{webcenterAdminSecurityBean.rolesTable}" id="tt2" styleClass="AFStretchWidth" autoHeightRows="150">
<f:facet name="nodeStamp">
<af:column width="260"
selected="false" noWrap="false" id="c3">
<f:facet name="header">
<af:outputText value="#{uib_o_w_w_r_WebCenter.LABEL_PERMISSIONS}"
id="ot5"/>
</f:facet>
<af:panelGroupLayout id="pgl26">
<af:forEach items="#{bindings.getRoleHeaders.result}" var="role">
<af:outputText value="#{role.value}" visible="false" id="ot1"/>
<af:selectBooleanCheckbox selected="#{node.dataProvider.serviceActions[role.value]}"
rendered="#{!node.dataProvider.serviceHeader}"
label="#{null}"
disabled="#{(node.dataProvider.readOnly and role.seededRole) or node.dataProvider.actionDisabledMap[role.value] == true}"
simple="true" id="sbc2">
<f:attribute name="permission" value="#{node}"/>
</af:selectBooleanCheckbox>
</af:forEach>
<af:spacer width="5" id="s2"/>
<af:outputText value="#{node.name}" noWrap="false" id="ot2"
inlineStyle="#{node.dataProvider.serviceHeader? 'font-weight:bolder;': ''}"/>
</af:panelGroupLayout>
</af:column>
</f:facet>
<af:column headerText="#{uib_o_w_w_r_WebCenter.LABEL_DESCRIPTION}" rowHeader="unstyled" noWrap="false" id="c1">
<af:outputText value="#{node.description}" noWrap="false"
inlineStyle="color:grey;" id="ot3"/>
</af:column>
</af:treeTable>
</f:facet>
</af:panelStretchLayout>
</jsp:root>
This taskflow is included as a region within another page :
<af:commandToolbarButton id="cb3"
shortDesc="#{uib_o_w_w_r_WebCenter.LABEL_EDIT_PERMISSION_HINT}"
icon="/adf/webcenter/edit_sm_ena.png"
text="#{uib_o_w_w_r_WebCenter.LABEL_EDIT_PERMISSION}"
inlineStyle="align:left">
<af:showPopupBehavior popupId="managePopup"/>
</af:commandToolbarButton>
<af:popup id="managePopup" contentDelivery="lazyUncached">
<af:dialog modal="true" type="cancel"
title="#{requestContext.formatter[uib_o_w_s_r_Spaces.EDIT_ROLE][pageFlowScope.o_w_wa_spacesRoleBacker1.selectedRole.value == webcenterAdminSecurityBean.spacesUsersRole ? uib_o_w_s_r_Spaces.LABEL_AUTH_USER : pageFlowScope.o_w_wa_spacesRoleBacker1.selectedRole.value]}"
titleIconSource="/adf/webcenter/empty.png" id="d4">
<af:region value="#{bindings.editroletaskflow.regionModel}"
id="r2"/>
<f:facet name="buttonBar">
<af:commandButton partialSubmit="true"
text="#{uib_o_w_w_r_WebCenter.LABEL_SAVE}"
actionListener="#{o_w_w_i_v_b_webCenterViewUtilsBean.saveChangesAndCloseWCLinksPopup}"
id="cb4">
<f:attribute value="#{bindings.editroletaskflow.regionModel}"
name="wcRegionModel"/>
<f:attribute value="bindings.saveRoles.execute"
name="wcMethodToExecute"/>
</af:commandButton>
</f:facet>
</af:dialog>
</af:popup>
In the main page, there is a table, I select one row and then click on this commandButton, which launches the popup.
The problem here is that when I launch the popup, there are many rows in the table and hence a scroll bar appears. Scroll down the popup and close the popup.
Again I launch the popup, I see that the popup displays in the same state as it was closed before, i.e the scrollbar is at the bottom and the first row is not displayed.

...also do not forget to:
1. adjust the Active property for the task flow binding (in the pageDef).
Set property value to the true on popupFetchListener, and to the false when closing popup
2. for the af:popup containing region, set childCreation to deffered
