Subject [C2] Problem with with transformer called more than once.
Date Sat, 30 Jun 2001 12:44:39 GMT
Hi there,

  I started using transformers and encounter some behaviour which I don't
understand. If I call the transformer more than once or twice I encounter a
NullPointer Exception. I don't have a clue why?

  I am using C2 from the current CVS.

  I attached the code and inlined the log and an extract from the sitemap.

Mariano

>From sitemap.xmap.

   <map:match pattern="pf.html">
    <map:generate src="exp1/PortfolioValuationDefinition.xml"/>
    <map:transform type="reportDefinition"/>
    <map:serialize/>
   </map:match>


from the log

Works ok.
