How to include dynamically subview define in separate file?

Question

Hi all,
I am new to JSF and I'm currently using the MyFaces implementation,
I would like to do something like:
<t:dataTable value="#{mgr.rowDataModel}" var="row">
<t:columns value="#{mgr.columnDataModel}" var="column">
// <h:outputText value="#{mgr.file.url}" /> -------> display the url of the subview to be included
<%@include file="xxxxxxx"%> //or else ???
</t:columns>
</t:dataTable>
where the files contain f:subview definition and rowDataModel and columnDataModel are javax.faces.model.DataModel.
Here, I do not know how to set the 'xxxxxxx' value of the include file attribute. #{mgr.file.url} does not work
I try to approach the whole thing from the JAVA side using a binding to a managed bean that return a panel grid something like
<h:panelGrid binding="#{mgr.myPanelGrid}" />
but here, I don't know how to create the subview from the url of the file that contains the subview from JAVA
I may approach the whole thing on a wrong way
Can someone point me to the right direction?
Thank you for your help

All XML documents should begin with an XML declaration.
If you have your fxml file starting with  the following lines :
<?xml version="1.0" encoding="UTF-8"?>
<!-- mylicense here -->
.. it will be loaded in Scene Builder, and saved back as is.
