Michael Mole commented on AXIS2C-753:
-------------------------------------
I looked at CADBBeanTemplateSource.xsl and it seems that this checking is only
done for array elements. This should generate code similar to the "setter"
methods.
So in the context of the above complexType, the serialize method should look
like this:
if ( _Foo->foo-element != NULL ) {
start_input_str = "<ns2:foo-element";
start_input_str_len = axutil_strlen(start_input_str);
end_input_str = "</ns2:foo-element>";
end_input_str_len = axutil_strlen(end_input_str);
axutil_stream_write(stream, env, start_input_str, start_input_str_len);
adb_foo-element_serialize(_Foo->foo-element,
env, current_node,
AXIS2_FALSE);
axutil_stream_write(stream, env, end_input_str, end_input_str_len);
}
Also, if minOccurs is not specified, perhaps it should return an error if
_Foo->foo-element is NULL.

> Project: Axis2-C
> Issue Type: Bug
> Components: code generation
> Affects Versions: 1.1.0
> Reporter: Michael Mole
> Priority: Critical
>
> I am using the code generation tool from approx. 11/1/2007 Axis2/Java nightly
> snapshot. I am using it to generate C databindings
> My generated adb databinding code is writing elements in the serialize method
> even when minOccurs="0". I think if anything has a minOccurs="0", the
> generated serialize should check if the element has been provided by
> surrounding the code block with an "if ( foo-element !- NULL )". Otherwise,
> the program will crash if the optional element has not been provided.
> I have a datatype defined as follows:
> <complexType name="Foo">
> <sequence>
> <element name="foo-element" type="foo_type"
> minOccurs="0">
> </element>
> </sequence>
> </complexType>
> In my serialize method I'm seeing something like this:
> start_input_str = "<ns2:foo-element";
>
> start_input_str_len = axutil_strlen(start_input_str);
> end_input_str = "</ns2:foo-element>";
> end_input_str_len = axutil_strlen(end_input_str);
>
> axutil_stream_write(stream, env, start_input_str,
> start_input_str_len);
>
> adb_foo-element_serialize(_Foo->foo-element,
>
> env, current_node,
> AXIS2_FALSE
> );
>
> axutil_stream_write(stream, env, end_input_str,
> end_input_str_len);
