Subject RE: Processing BodyContent in doAfterTag() has no effect
Date Fri, 08 Mar 2002 22:57:41 GMT
Thanks for your help. But I don't think that is
causing the problem:
  (a) for one thing, the other text written to
     body content show up in the output. Only the
     stuff inserted into the enclosing writer in
     doAfterBody() is mysteriously missing.

  (b) I am writing to the enclosing JspWriter -
      not to the body content.

Consider the following:

      <body>
          <kobe:Filter> 
            I am a Laker Fan. I am Kobe.
          </kobe:Filter>
      <body>

What appears on output is:
     I AM A LAKER FAN I AM KOBE

The periods are missing. What (I think) my doAfterBody()
is doing is to replace "." tokens with ".<br>" tokens.
Can you tell me where the <br> tokens that I inserted
vanished?

     /K
