Description Geoffrey T Falk 2005-01-30 01:31:30 UTC 
Found in jakarta-taglibs-standard-1.1.2:

When trying to apply fn:length() to something that is not a Collection, String, 
Enumeration or Iterator, this misleading exception is generated:

  "Don't know how to iterate over supplied "items" in <forEach>"

It should say that the argument to fn:length() is invalid.

This cost me much time debugging in the wrong area of a JSP page. Thanks for 
your attention.

I fixed the error message in org/apache/taglibs/standard/functions/Functions.java.

The fix was commited by Pierre Delisle (thanks Pierre).

Marking this bug fixed.
