Thanks for the reply. Actually the class is a pojo, with properties,
getters and setters. I tried using "field" attribute instead of
"get-method and set-method" in the collections element that did not
solve it. I still get a null reference for the collection during
unmarshalling when the element "list" is missing from the input xml.
<binding>
<mapping name="A" class="a">
<structure
name="list"
usage="optional"
test-method=" testListIsNullOrEmpty">
<collection
field="list"
factory="package.Factory.listFactory" <!-this method creates and
returns an ArrayList -->
item-type="item"
</structure>
</mapping>
<mapping ---- for item --/>
</binding>
Regards,
Sunil

>From what I could read, you will need to use post-set on your
collection. In the post set method, you will check if the object
attribute is set to null and adjust accordingly. Since I didn't see any
field attribute in the XML, I'm not sure if this would work since it
looks like your A class extends from ArrayList or something. I have to
say, that I didn't need to implement any post-set in my own application,
so this is only from doc.

Subject: Re: [jibx-users] Null Collection Fields
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
