I have code like the above in my jetspeed.vm and have just switched
to the latest jetspeed code from CVS - I am getting a problem where
the first portlet has the content displayed before the title, but
then the remainding portlets are displayed correctly.

Could this be a velocity problem - something to do with the #set
command?

Thanks for any insights,
Chris

This is related to the JSP inside Velocity fix: since JSP always stream
their response and it's not possible to intercept their response in servlet
2.2 environments; the default behavior for VelocityPortlet is now
to stream its response directly.

You can simply subclass VelocityPortlet.java to VelocityBufferedPortlet.java,
copy getContent() and patch it this way:

151c151
<             TurbineVelocity.handleRequest(context, templatePath, rundata.getOut());
---
 >             s = TurbineVelocity.handleRequest(context, templatePath);

You can then use the VelocityBufferedPortlet as the parent for your portlets that

require this title manipulation and keep the base VelocityPortlet for the others
(especially the Customization portlets that need the streaming features to work).
