Hi,
I'm trying to build a simple custom logicsheet with
string conversion functions (sample code attached).
Everything works fine as long as I pass parameters for
the Java functions as attributes, but not when passing
parameters as content of a custom tag.
(tried this for several hours and searched the web for
more info, no success)
I used the docs and examples from:
...\cocoon-2.0\docs\userdocs\xsp\logicsheet-concepts.html
and the
[C2] Example Taglib from Gary Clark Tue, 19 Jun 2001 08:13:50 -0700
(seems to be a mailing to this list)
Can anybody help ?? (Cocoon2.0 / Tomcat4.0.1 / Win2000 / JDK 1.3)
Thanks,
Friedrich Schuster
