Subject cvs commit: jakarta-jetspeed/src/java/org/apache/jetspeed/util/template JetspeedTemplateLink.java PortletTemplateLink.java
Date Tue, 05 Mar 2002 12:26:33 GMT
sgala       02/03/05 04:26:33

  Modified:    src/java/org/apache/jetspeed/portal/portlets
                        VelocityPortlet.java
               src/java/org/apache/jetspeed/util/template
                        JetspeedTemplateLink.java PortletTemplateLink.java
  Log:
  Change the mechanism to have jlink in the toolbox. Instead of instantiating a new one for
each request, leave the work to turbine, and setPortlet() of the right one in the rendering
code. This deprecates the whole PortletTemplateLink class (I should have removed it, but...)
as now JetspeedTemplateLink is able to deliver context sensitive links for Panes. I hope I
won't break anything.
