Pass parameter to page fragment in dynamic region

Question

Hello.
I am using Jdeveloper 11.1.1.3.
Can anyone explain to me how to pass parameter to page fragment in dynamic region?
My situation is:
I have only 1 page: index.jspx.
This page include 2 elements:
1. <af:tree>
<af:tree id="t1" var="node" rowSelection="single"
value="#{bindings.FpsrVO1.treeModel}" rendered="true" expandAllEnabled="true"
contentDelivery="lazy" initiallyExpanded="false"
contextMenuSelect="false" fetchSize="-1">
<f:facet name="nodeStamp">
<af:commandLink id="cl1" rendered="true"
actionListener="#{backingBeanScope.RegionDynamicBean.treeClick}">
<af:outputFormatted id="outForm" value="#{node.Name}" rendered="true"/>
<f:attribute name="menuId" value="#{node.Code}"/>
</af:commandLink>
</f:facet>
</af:tree>2. <af:region> :
<af:region value="#{bindings.dynamicRegion1.regionModel}"
id="r1"/>Region could be changed to 3 bounded taskFows wich have only one page fragment.
Can anyone explain to me how i can send <f:attribute name="menuId" value="#{node.Code}"/> from tree element to page fragment which will be rendered on screen?

You can pass a map to the dynamic region which would take the task flow parameters as key-value pairs.
<taskFlow id="dynamicRegion1"
taskFlowId="${backingBeanScope.TestPageBean.dynamicTaskFlowId}"
activation="deferred"
xmlns="http://xmlns.oracle.com/adf/controller/binding"
parametersMap="#{backingBeanScope.TestPageBean.parameters}"/>
When reloading the taskflow, ensure that the necessary parameters are loaded into the taskflow.
Check this example exactly based on your use-case:
