Grzegorz Grzybek commented on CXF-5254:
---------------------------------------
Hello
Tomorrow I'll post the patch (or pull request for Git). But now (oh these
timezones...) some observations:
* IDL/Corba Arrays are the same as Sequences (correct me). In WSDL/XSD and
while creating corba binding, arrays are sequences that have
maxOccurs==minOccurs and both are greater than one
* so the "wrapping" should be handled for both arrays and sequences
* sequences and arrays may be named or anonymous. So we have problems designing
class hierarchy - anon/named and sequence/struct - this is ugly in
{{/rt/bindings/corba/src/main/resources/schemas/wsdl/corba-binding.xsd}}
* I have prepared interesting type for tests (it covers all 8 combinations):
{code:xml}
<complexType name="MixedArray">
<sequence>
<!-- unwrapped sequence -->
<element maxOccurs="unbounded" minOccurs="0" name="array1"
type="string"/>
<!-- wrapped sequence -->
<element maxOccurs="1" minOccurs="1" name="array2"
type="x1:UnboundedArray"/>
<!-- unwrapped array -->
<element maxOccurs="3" minOccurs="3" name="array3"
type="string"/>
<!-- wrapped array -->
<element maxOccurs="1" minOccurs="1" name="array4"
type="x1:FixedArray"/>
<!-- anonymous unwrapped sequence -->
<element maxOccurs="unbounded" minOccurs="0" name="array5">
<simpleType>
<xsd:restriction base="string" />
</simpleType>
</element>
<!-- anonymous wrapped sequence -->
<element maxOccurs="1" minOccurs="1" name="array6">
<complexType>
<sequence>
<element maxOccurs="unbounded" minOccurs="0" name="item"
type="string"/>
</sequence>
</complexType>
</element>
<!-- anonymous unwrapped array -->
<element maxOccurs="3" minOccurs="3" name="array7">
<simpleType>
<xsd:restriction base="string" />
</simpleType>
</element>
<!-- anonymous wrapped array -->
<element maxOccurs="1" minOccurs="1" name="array8">
<complexType>
<sequence>
<element maxOccurs="3" minOccurs="3" name="item"
type="int"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
{code}
* the _special_ case in
{{/rt/bindings/corba/src/main/java/org/apache/cxf/binding/corba/types/CorbaStructEventProducer.java}}
should not be controlled by the _primitiveness_ of sequence elements, but
rather by your "wrapped" flag - correct me if I'm wrong
* there were some problems with {{CorbaStructListener}} so the patch contains
some changes
* there were problems with finding corba types for anonymous XSD types, so the
patch contains changes in {{WSDLToCorbaHelper}}
