Sitemap problem : ContentAggregator.recycle

[Barbara Post <ba...@ifrance.com>]

Hello, I get the following with C 2.0.3... (should I upgrade to 2.0.4 ? I
have to use a "release" for my project... :-/ ). I use Tomcat 4.0.4 and the
error is written in Tomcat's window. (using Windows NT).

java.lang.NullPointerException

My pipeline is indeed pretty complicated. It worked until I added the
"map:act type="reqparams-exists". (RequestParameterExistsAction)

Indeed I have to perform a form validation only if the form has been
submitted at least once, this is why I check whether "CustomerID" is in the
req. parameters.

Any idea ? Thanks a lot !
I use Sunrise authentication and Christian's SimpleFormTransformer.
