When you use <esql:get-columns> and one of your column has a NULL value,
you find yourself with a disgracefull NullPointerException. Here is a patch
for Cocoon2 to have an empty tag instead :
Index: esql.xsl

This solution is inspired from the patch posted by Matthew Cordes on
2001-02-22 about the same problem but applying to Cocoon1.
Comments are very welcome.
