Subject Re: minOccurs and nillable

Anne,

Yes, I came to the conclusion there was a difference, but I added both
purely to try and persuade Axis to handle the error. 

I think Axis is ignoring the minOccurs="0", despite the fact I can see it
being set up in the source code generated:

        elemField = new org.apache.axis.description.ElementDesc();
        elemField.setFieldName("requestCategoryCode");
        elemField.setXmlName(new javax.xml.namespace.QName("http://www.caps-solutions.co.uk/schema/uniform/72b/servicerequest/sr/srtypes","RequestCategoryCode"));
        elemField.setXmlType(new javax.xml.namespace.QName("http://www.caps-solutions.co.uk/schema/uniform/72b/common/uniformtypes",
"CNCODE_CodeValue"));
        elemField.setMinOccurs(0);
        elemField.setNillable(true);
      
Can this really be an Axis bug? I thought this would be fairly heavily tested?
