Order of namespace declarations for taglibs?
Hi people,
I posted this question on the users list three days ago, but got no
reply, so I thought I'd better bother you :). In the meantime I
partially solved the problem but uncovered a possible bug in C2.RC1a (or
Xerces or Xalan).
........................................................
I have a problem in C2.0rc1a with one of my logicsheets. This logicsheet
uses another builtin taglib, like for instance xsp-request (please have
a look at the attached test.xsl file). The problem is that the elements
of the xsp-request taglib are NOT expanded by the XSP generator, so they
are copied verbatim to the output. The attached test1.xsp file, when
processed, produces the output that is contained in the attached
test1.xml file.
This only happens with the RC1a release, whereas everything works
correctly with 2.0b2. The funny thing is that, if you restart the
servlet container and remove all work files, it works correctly with
2.0rc1a but ONLY THE FIRST TIME the page is requested. If you reload the
page, the bug manifests itself.
I have verified this behavior with Tomcat 4.0 under Linux and with
Tomcat 3.2.3 under Solaris 8 (BTW, I cannot compile mod_webapp under
Solaris 8, so I am forced to use Tomcat 3.2.3, but this is a problem for
the Tomcat list).
........................................................
Having had no reply, I tried to change the order of namespace
declarations and "fixed" the problem. I have concluded that, if the
"test" taglib logicsheet uses the "xsp-request" taglib, everything works
ONLY if, in the XSP document, the namespace declaration for "test" comes
BEFORE the namespace declaration for "xsp-request". That is, in the
attached test1.xsp file, change
<xsp:page language="java"
xmlns:xsp="http://apache.org/xsp"
xmlns:xsp-request="http://apache.org/xsp/request/2.0"
xmlns:log="http://apache.org/xsp/log/2.0"
xmlns:test="http://caterina.cbim.it/xsp/test/1.0">
to
<xsp:page language="java"
xmlns:xsp="http://apache.org/xsp"
xmlns:log="http://apache.org/xsp/log/2.0"
xmlns:test="http://caterina.cbim.it/xsp/test/1.0"
xmlns:xsp-request="http://apache.org/xsp/request/2.0">
Under C2b2 this is not the case, the order does not matter.
I was under the impression that the order of namespace declarations is
irrelevant in XML and that parsers and/or XSLT processors are not
required to report them to the application in any particular order.
Should this behavior be classified as a bug or as an undocumented
feature? ;)
Best Regards,
Ugo

It does. Look at the test.xsl file attached to the original message.

Ugo,
Also in your test taglib make sure that it references xsp-request in the namespace declarations.
Thanks,

Hi Ugo,
could you please try the Xalan and Xerces version provided with the b2
in the c2rc1a? This way we could find out if it is a cocoon related problem,
or (hopefully) a xalan/xerces problem.
