I18nMessage - null parameter values causes NPE
----------------------------------------------
Key: COCOON-1785
URL: http://issues.apache.org/jira/browse/COCOON-1785
Project: Cocoon
Type: Bug
Components: Blocks: Forms
Versions: 2.1.8, 2.1.9-dev (current SVN)
Reporter: Eric Meyer
Attachments: I18nMessageNPE.txt
Putting a null in a parameter value causes an NPE when creating the SAX events
java.lang.NullPointerException
at org.apache.cocoon.forms.util.I18nMessage.toSAX(I18nMessage.java:128)

Note: this NPE then causes the Ajax transformer to go wonky for all users in
all sessions. I'm still digging into that one.
I am attaching a patch (license granted to ASF) that allows null parameter
values (using String.valueOf(parameters[i]) so that nulls are turned into
"null".
