For this particular case you should be able to restructure your binding 
definition to avoid the problem by replacing the structure with this:

  <collection name="ProductTypeList" usage="optional" 
item-type="com.aaa.ProductTypeLne" field="productTypeLne"/>

The key here is that the <structure> handling currently won't reach down 
into child binding components to see if something is actually present 
when marshalling. Another way of handling this would be to add a simple 
test-method for the <structure> that just checked if the productTypeLne 
field was non-null.
