How to set a property reference to an empty collection instead of null
during unmarshalling when the associated element is missing from the
input xml.
This binding causes the property to be null when the corresponding
element (list) is missing from the xml:
<binding>
<mapping name="A" class="a">
<collection
name="list"
get-method="getList"
set-method="setList"
factory="package.Factory.listFactory" <!-this method creates and
returns an ArrayList -->
item-type="item"
usage="optional"
test-method="testListIsNullOrEmpty" />
</mapping>
<mapping ---- for item --/>
</binding>
I changed the above to the following, it did not help.
<binding>
<mapping name="A" class="a">
<structure
name="list"
usage="optional"
test-method=" testListIsNullOrEmpty">
<collection
get-method="getList"
set-method="setList"
factory="package.Factory.listFactory" <!-this method creates and
returns an ArrayList -->
item-type="item"
</structure>
</mapping>
<mapping ---- for item --/>
</binding>
What is the binding missing? Would using post-set method for this
purpose cause any issues/unwanted side effects?
Thanks.

Sunil
