Hi,
In my last message, I meant to say to check the thread: Using Ids in which I posted a question similar to yours (with no answer).
I have simplified my mapping and xml file to a minimum. Here they are:
BINDING:
========
<binding>
<mapping name="ItineraryRendition" class="com.agencebraque.jetsgo.itineraryserver.entities.ItineraryRendition">
<collection name="ItineraryList" add-method="addItinerary" iter-method="getItineraryIterator"/>
<collection name="PassengerInfoList" add-method="addPassengerInfo" iter-method="getPassengerInfoIterator"/>
</mapping>
<mapping name="Itinerary" class="com.agencebraque.jetsgo.itineraryserver.entities.Itinerary">
<structure name="pnr" get-method="getPnr" set-method="setPnr" type="com.agencebraque.jetsgo.itineraryserver.PNR.entities.ItineraryPNR">
<collection name="passengers" add-method="addPassengers" iter-method="getPassengersIterator">
<structure name="PassengerInfo" >
<value style="attribute" name="refid" type="com.agencebraque.jetsgo.itineraryserver.PNR.passenger.entities.PassengerInfo" ident="ref"/>
</structure>
</collection>
</structure>
</mapping>
<mapping name="PassengerInfo" class="com.agencebraque.jetsgo.itineraryserver.PNR.passenger.entities.PassengerInfo">
<value style="attribute" name="id" get-method="getId" set-method="setId" ident="def"/>
</mapping>
</binding>
XML FILE:
========
<?xml version="1.0" encoding="UTF-8"?>
<ItineraryRendition>
<ItineraryList>
<Itinerary>
<pnr>
<passengers>
<PassengerInfo refid="N10093"/>
</passengers>
</pnr>
</Itinerary>
</ItineraryList>
<PassengerInfoList>
<PassengerInfo id="N10093">
</PassengerInfo>
</PassengerInfoList>
</ItineraryRendition>When compiling my binding, I get the following exception.
EXCEPTION:
==========
java.lang.NullPointerException
at org.jibx.binding.def.PropertyDefinition.getName(PropertyDefinition.java:307)
at org.jibx.binding.def.ValueChild.createBackfillClass(ValueChild.java:185)
at org.jibx.binding.def.ValueChild.genParseIdRef(ValueChild.java:283)

at org.jibx.binding.def.NestedStructure.genAttributeUnmarshal(NestedStructure.java:118)
at org.jibx.binding.def.ElementWrapper.genContentUnmarshal(ElementWrapper.java:248)
If anybody has any clue, please let me know.
Thank you,

Hi Linus and Jibx users/developers,
I sent a similar message last week (see title: Problem with jibx ref and def) but did not get an answer. I also saw that a bug was in JIRA: [jira] Created: (JIBX-19) NullPointerException in ident="ref" within collection.
It says that it is due to forward references but even after eliminating those references (my XML is not static and I can therefore modify it) I still get the same exception.
If anybody has got this to work please help us out, I'm running out of ideas.
Thanks a lot,
Francois

I have the following mapping:
<collection name="InstalledItems" add-method="addHardwareInstallation" iter-method="getInstalledHardwareIterator" > <value name="Installation" type="edu.iris.dmc.isis.HardwareInstallation" ident="ref" /> </collection>
And I get a NPE when I try to compile the binding.
(from runtime binding:)

If I change the getName() method in PropertyDefinition to spit out toString() at that point, I get:
[java] noSet for: property from collection (edu.iris.dmc.isis.HardwareInstallation)
HardwareInstallation has a defined value for ident="def" .
Trying to figure out what I'm doing wrong...
