Carol,
I saw this behaviour as well when I tried changing the layout of the
default.jsp file. What I discovered is that apparently the ecsscreen
taghandler (the class that gets called to process the <jetspeed:ecsscreen>
tag element) apparently is not using the output stream of its parent
container, but using the base output stream. As a result the output
buffered in the parent stream doesn't show up until after the ecsscreen
output.
Since I was trying to put together a proof of concept demo before going on
holiday, I didn't look into the ecsscreen source code to see exactly what
the problem was, but I did find that adding the following immediately before
the <jetspeed:ecsscreen> tag allowed me to work around the problem and
continue my demo.
Add the following just before the <jetspeed:ecsscreen> tag:
<% out.flush(); %>
This will cause the parent buffer to be flushed before calling the ecsscreen
tag handler.
Cheers,
- Tim Taylor
