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 and 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.
