Stuts plugin can display links from jsp page to actions and other jsp pages on diagram. That is grate! But if you use tiles plugin you don't work with jsp pages directly. Instead you work with tiles definition. For example
<definition name="..." path="/WEB-INF/jsp/template.jsp">
<put name="content" value="/WEB-INF/graph.jsp"></put>
</definition>
Both template.jsp and graph.jsp are jsp pages and have links but struts plugin does not understand this. So links from these pages are not displayed in struts diagram.
Also it would be nice if there were way to select jsp page for "value" attribute in "put" element in tiles editor (like for "path" attribute in "definition" element).
