Hello,
I am trying to create a schema from scratch. When I try to call validate()
on the schema after creating the first complex element it gives this
exception. Any thoughts on what might be wrong would be much appreciated.
Thanks for your help.

Kaunteya,

It looks like a bug in XSD that would be fixed like this:

If you call updateElement on your schema, you might be able to avoid this bug until it's fixed in the next drop (of the new
1.1.0 version) hopefully later this week...

Kaunteya,
It looks like a bug in XSD that would be fixed like this:
<blockquote>> etools-diff XSDSimpleTypeDefinitionImpl.java
 3547c3547
 <     &a mp;nbsp;   if (element.hasAttributeNS(null,
attributeName))
 ---
 >           if (element !=
null && element.hasAttributeNS(null, attributeName))</blockquote>

 If you call updateElement on your schema, you might be able to avoid
this bug until it's fixed in the next drop (of the new 1.1.0 version) hopefully
later this week...

<blockquote TYPE=CITE>Hello,
 I am trying to create a schema from scratch. When I try to call validate()
 on the schema after creating the first complex element it gives this
 exception. Any thoughts on what might be wrong would be much appreciated.
 Thanks for your help.
