It's possible to do next by jsf facelets?
I want to extend reusable.xhtml with additional html columns
reusable.xhtml
<ui:composition> <table class="table table-striped table-hover table-condensed"> <thead> <tr> <ui:insert name="additional_headers"></ui:insert> </tr> </thead> <tbody> <c:forEach items="${beanChooser.chosenBean.entitiesToShow}" var="item"> <tr id="#{beanChooser.chosenBean.shortEntityName.toLowerCase()}${item.id}"> <td> </td> <td> </td> <ui:insert name="additional_columns"></ui:insert> </tr> </c:forEach> </tbody> </table> </ui:composition> <html> <ui:composition template="/masterTemplate.xhtml" ...> <ui:define name="content"> <ui:include src="../reusable.xhtml"> <ui:define name="additional_columns"> <td> Additional EL Expression </td> </ui:define> <ui:define name="additional_headers"> <th> STATIC </th> </ui:define> </ui:include> </ui:define> </ui:composition> </html> if it's not impossible, what is the best practice to achieve this?
