[castor-dev] ValidationException: dd is a required field.; doing marshaling

[Bruno Cadonna]

hi,

i sent this email already last week to this mailing list and nobody 
didn't answer me. maybe i explained my problem not clear enough.
anyway i try again!

i have following problem.

due to tests i made a xml-file directly with the generated classes of 
castor 0.9.5. by creating the objects by myself (using castor's 
generated classes, but without unmarshalling) and then i marshaled them 
in order to get the xml-file in xml format.
this is my test xml-file:

<dl>
  <dt>
    <txt>test data</txt>
  </dt>
  <dd>
    <txt>test definition</txt>
  </dd>
  <dt>
    <txt>test data 2</txt>
  </dt>
  <dd>
    <txt>test definition 2</txt>
  </dd>
</dl>
the relevant part of my schema is:

<xs:element name="dl">
  <xs:complexType>
    <xs:sequence maxOccurs="unbounded">
      <xs:element ref="dt"/>
      <xs:element ref="dd"/>
    </xs:sequence>
    </xs:complexType>
</xs:element>
<xs:element name="dd">
  <xs:complexType>
    <xs:choice minOccurs="0" maxOccurs="unbounded">
      <xs:group ref="content-mix.group"/>
    </xs:choice>
  </xs:complexType>
</xs:element>
<xs:element name="dt">
  <xs:complexType>
    <xs:choice minOccurs="0" maxOccurs="unbounded">
      <xs:group ref="content-mix.group"/>
    </xs:choice>
  </xs:complexType>
</xs:element>
when i marshal it i get the exception:
ValidationException: dd is a required field.;
but when i change the sequence to a choice (with the same maxOccurs 
attribute) all works fine.

i tried to unmarshal and then to marshal the xml-file leaving the 
sequence in the complexType and it works as well.

shouldn't it work also when i create the object by myself?

maybe i forget to set anything, when i create the xml-file as java object.

could somebody help me?

bye
bruno
