structure mapping with all values optional does is unmarshalled as null when
none of the values is defined (in context of an collection)

Project: JiBX
Type: Bug

Versions: 1.0-RC0
Environment: windows, linux

Hi *,
I am experiencing problems when I try to bind structures in collections where
all attributes the structure defines are optional, e. g.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE binding SYSTEM "binding.dtd">
<binding>
<mapping name="outer" class="com.ars_subtilior.test.jibx.Outer">
<value name="name" field="name" usage="optional"
style="attribute"/>
<collection
factory="com.ars_subtilior.test.jibx.Outer.createCollection"
field="items" usage="optional" ordered="false">
<structure name="inner"
type="com.ars_subtilior.test.jibx.Inner"
value-style="attribute" usage="optional">
<value name="name" usage="optional"
field="name"/>
<value name="i" usage="optional" field="i"
default="0"/>
<value name="woop" usage="optional"
field="woop"/>
</structure>
</collection>
</mapping>
</binding>
When I unmarshal a xml file like the following:
<?xml version="1.0"?>
<outer name="outerName">
<inner name="innerName"/>
<inner/>
</outer>
only one Inner gets created but the collection (Outer.items) contains two
entries, the first one is the Inner that got created for <inner
name="innerName"/>, the second one is null.
I have attached a zip file that contains everything that is needed to reproduce
the behaviour (it is an Eclipse project [sorry for naming it jibx_error]).
The problem arises with RC 0 and RC 1.
Thanks,
