Hi,
when I Marshal a Object which was generated with Castor and then try to
Unmarshal the Document
I get the Message "-error-if-this-is-used- is a required field."
The problem is this xsd Fragment:
<xsd:complexType name = "Family">
<xsd:sequence>
<xsd:element name = "Version" type = "xsd:integer"/>
<xsd:choice>
<xsd:element name = "PropertyScope" type = "tdx:Code"
minOccurs = "0" maxOccurs = "unbounded">
<xsd:annotation>
<xsd:documentation>
Code des Herstellers oder Suppliers als
Verweis auf alle der Familie zugeordneten Properties
</xsd:documentation>
</xsd:annotation>
</xsd:element>
<xsd:element name = "PropertyUsage" minOccurs = "0"
maxOccurs = "unbounded">
<xsd:annotation>
<xsd:documentation>
Code des Herstellers oder Suppliers als
Verweis auf alle der Familie zugeordneten Properties
</xsd:documentation>
</xsd:annotation>
<xsd:complexType>
<xsd:simpleContent>
<xsd:extension base = "tdx:Code">
<xsd:attribute name = "isOptional"
default = "true" type = "xsd:boolean"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
</xsd:element>
</xsd:choice>
</xsd:sequence>
</xsd:complexType>
When I Marshall the Object it works fine. In the generated result-File
there is one "Family" which has
no "PropertyScope" and no "PropertyUsage". Which seem to be OK.
But when I Unmarshal the File it says to me "-error-if-this-is-used- is
a required field.". Which means
that he is waiting for a "PropertyScope" or a "PropertyUsage" Element.
Is there something wrong with the schema? Choice means that there have
to be one element. - "PropertyScope"
or "PropertyUsage". But their minOccur could be "0".
regards,
Stefan
