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...
