Description

I encountered a null pointer exception when using the source generator ant task to generate java files for an xsd schema. The error seems to occur whenever a complex type that extends another type contains an xs:any element. I have attached a sample schema to demonstrate. When processed, the following stack trace occurs:

Thanks, Dave, we'll be looking into this. Just out of curiosity, is this something that just occurred to you for the first time, or is this a result of e.g. upgrading from an old release. I am just trying to get an idea of the context.

This is the first time I've used Castor, so version 1.1 is the only one I have tried this with.

Patch for review. This basically removes all NPEs from the code generation run, and the CTF still completes. Having said that, would you have a minimal XML document instance that matched that schema, to ease our life to get a new CTF test integrated ?
