Re: [jibx-users] TypedArrayMapper and inheritance problem

[Dennis Sosnoski]

One problem here appears to be that you're telling the TypedArrayMapper 
to use an element <adresses> around the list of items present in that 
array. When unmarshalling the <adresses> start tag is not found, so the 
runtime thinks the whole (optional) array is not present in the 
document. I don't know why that element would be missing, if the 
document you showed was generated by marshalling with the same binding - 
I suspect you actually generated it using a different binding definition.

Another problem is that you've got ordered="false" on your mapping for 
subAdress, with two child elements both named "number". That probably 
should be checked as an error by JiBX, but if you think about it you 
should see that there's no way the runtime can tell which <number> 
element is which. Generally you should stay with the default of 
ordered="true" unless you really need unordered elements.

Hi,
I’m trying to write a binding that uses the
org.jibx.extras.TypedArrayMapper to
marshall/unmarshall an array of objects.  The binding
compiles OK when having the binding defined like this:
<binding>
	<mapping class="jibxtest.Person" name="person"
ordered="false" >
		<value name="personNumber" 		field="personNumber"
usage="optional"/>
		<structure field="adresses" 	usage="optional"/>
	</mapping>
	
	<mapping class="jibxtest.Adress"  abstract="true"
ordered="false" >
		<value name="number" 	field="number" 
usage="optional"/>
	</mapping>
	
	<mapping class="jibxtest.Adress[]" name="adresses"
marshaller="org.jibx.extras.TypedArrayMapper"
unmarshaller="org.jibx.extras.TypedArrayMapper" />
	
	<mapping class="jibxtest.SubAdress"  name="subAdress"
ordered="false" extends="jibxtest.Adress">
		<structure map-as="jibxtest.Adress"
usage="optional"/>
		<value name="number" 	field="subNumber" 
usage="optional"/>
	</mapping>
</binding>

While Adress is an superclass of subAdress and the
Person contains an Array of adresses. At rutime I add
subAdress objects to the Adrdess Array. Marshalling
works but when I unmarshall the following xml:
<?xml version="1.0" encoding="UTF-8"?>
<person>
   <personNumber>personNumber</personNumber>
   <subAdress>
        <number>4</number>
        <number>subNumber1</number>
   </subAdress>
</person>
I get an the following exception:
org.jibx.runtime.JiBXException: Expected end tag,
found start tag "number" 

Unmarshalling works too when I add <addresses> tags
around the <subadress> by hand - but this is not a
solution!
does anyone have experience with the TypedArrayMapper
and is able to help?
