Hello -
I have been working with Castor for a few days now, and have run into a
problem with my XML file (XML file included below).
I have this XML schema which I created based on my newbie knowledge of
XML schema's, and have verified it's validity with a schema checker
(xmlqualchckr).
When I try to generate code using Castor's Source Generator, and I get
the exception (java.lang.StackOverflowError). (Stacktrace is attached
below the XSD FILE).
However, if I change the XML file by commenting out the additional
recursion line which I am needing (see XSD file), then SourceGenerator
generates the source from the XSD file and everything works fine.
Any helpful suggestions are greatly appreciated.
Regards,
Vanita
