Region Popup Dialog doesn't show up in Detach mode

Question

issue description:
1.     There is a task-flow: filter-task-flow.xml, there is method call as default activity and always route to next one view activity filter , refer to below filter.jsf code
<af:panelGroupLayout id="pgl1" layout="vertical">
<af:popup childCreation="deferred" autoCancel="disabled" id="filterpopup" binding="#{backingBeanScope.filterBean.p1}" contentDelivery="lazy">
<af:dialog id="d2" ……/>
</af:popup>
</af:panelGroupLayout>
2.     In my report.jsff page, there is a command button and a region with filter-task-flow.xml , refer to below
<fnd:applicationsTreeTable featuresOff="wrap " actionsMenuRendered="false" primaryToolbarRendered="true" secondaryToolbarRendered="true" >
<f:facet name="treeTable">
<af:treeTable …..>
</af:treeTable>
</f:facet>
<f:facet name="appsTreeTableSecondaryToolbar">
<af:toolbar id="t1">
<af:commandToolbarButton id="filter2" text="Filter" rendered="true" >
<af:showPopupBehavior triggerType="click" popupId=":::fr1:filterpopup"/>
</af:commandToolbarButton>
          </af:toolbar>
</ fnd:applicationsTreeTable>
<af:region value="#{bindings.filtertaskflow1.regionModel}" id="fr1"/>
3.     In page definition reportPageDef.xml for report.jsff page, there is below definition.
<taskFlow id="filtertaskflow1"
taskFlowId="/WEB-INF/…../filter/flow/filter-task-flow.xml#filter-task-flow"
xmlns="http://xmlns.oracle.com/adf/controller/binding"
activation="deferred">
<parameters>
<parameter id="selectedSubTab" value="#{backingBeanScope.apprAppraisalPMOCRBean.selectedSubTabKey}"/>
<parameter id="planId" value="#{backingBeanScope.apprAppraisalPMOCRBean.planId}"/>
<parameter id="mgrEventId" value="#{backingBeanScope.apprAppraisalPMOCRBean.mgrEventId}"/>
</parameters>
</taskFlow>
4.     Now if I go to this page(report.jsff) and click command tool bar button Filter , popup dialog works. And enter Detach mode, click Filter again, popup dialog works.
5.     But if I go the this page(report.jsff) and enter Detach mode before clicking Filter button, then try to click Filter button, popup dialog doesn’t show up without any issue/error in UI & console. Then I exit Detach mode, and click Filter button again, It will still not popup any more until you reopen the page and click Filter button firstly.
Appreciate for any suggestion. Thanks a lot.

resolved. just need move dialog from region to report.jsff page and keep table content in region. that's all
