Robert Liguori commented on XMLBEANS-379:
-----------------------------------------

I've conversed through e-mail with the creator of this JIRA issue.  

He noted the following in regards to recreating the issue:

"Reproducing the issue is a matter of finding the HL7 v3 schemas (never a simple \
task; possibly available somewhere here \
[http://www.hl7.org/v3ballot/html/index.htm]), running them through XmlBeans and then \
calling set_String on an instance of EnFamily.  Assuming that EnFamily is still \
defined as being empty with a non-empty ancestor you should be able to reproduce the \
bug."

>                 non-empty types

> mixed="true"> <xsd:annotation>
> <xsd:documentation>
> The character string data type stands for text data, primarily

> I'm trying to use the SimpleValue interface to get/set the string value of a \
> generated EnFamily class (and others).  However, the SchemaType for EnFamily has a \
> contentType of EMPTY_CONTENT, not MIXED_CONTENT.  And \
> XmlComplexContentImpl.set_String() throws an IllegalArgumentException if you try to \
> set the string value to a type that isn't no type or MIXED_CONTENT. I think that \
> either the type system should change to define a new MIXED_EMPTY_CONTENT type or \
> XmlComplexContentImpl should change to check the ancestor types to see whether \
> they're mixed before throwing the IllegalArgumentException. The workaround I'm \
> using is to add an extension to classes like EnFamily that I need to get/set text \
> in, and using an XmlCursor to get/set the text value.
