Page output is disappearing
Does anyone know any conditions under which writing to the JspWriter will
not result in any output? I have a custom taglib class that extends
BodyTagSupport. The doStartTag() method returns EVAL_BODY_BUFFERED. I then
have another custom
taglib class that is a child of this tag, which extends TagSupport. In
doStartTag(), this method gets the JspWriter and writes to it, however the
output does not appear to come out. This child custom taglib does not even
refer to the parent tag in any way. However if I remove the containing
parent tag from the JSP page, the output *does* come out. I am using Tomcat
5.0.19.

This happens even if the server has been up and running for a while, and
when I look at the manager html page, it indicates that the application is
running properly. The problem only happens when I have a specific custom
taglib included in the page.

Hitting a page while tomcat is still in the process of firing up or in the
middle or reloading the app will cause this.
Due to an architectural change, it happens more often in 5x than 4x.
I don't know all the particulars but it's been discussed on this list before.
You could probably find out more by searching the archives.

Off chance, are you using tag-pooling? Try turning that off and see what happens.
