Benson Margulies commented on CXF-1878:
---------------------------------------
On trunk, it stubbornly insists on working even with the Simple front end.
> Databinding HashMap of HashMap of a complex Object

> Key: CXF-1878
> URL: https://issues.apache.org/jira/browse/CXF-1878
> Project: CXF
> Issue Type: Bug
> Components: Aegis Databinding
> Affects Versions: 2.0.7
> Environment: Linux and Windows with JDK Sun 1.6.0_05 - 1.6.0_06 (it
> has been seen also on other jdk)
> Reporter: tomas darbois

> Hello, in the project I'm working on (a project based partly on CXF with
> aegis), I've got trouble with complex databinding. The developer, who has
> configured the cxf part, told me to send an email on the CXF mailing list
> about the problem we had in order to see where and why it happens.
> We want to be able to manage method with complex parameter like MyObject
> * MyObject with class attributes
> * String
> * String
> * ArrayList<HashMap,MySecondObject>
> * MySecondObject with class attributes
> * String
> * String
> * ArrayList<HashMap,Long>
> But we have the following issue "org.apache.cxf.aegis.DatabindingException:
> Couldn't instantiate class. null. Nested exception is
> java.lang.InstantiationException: null
> org.apache.cxf.binding.soap.SoapFault:" since
> ArrayList<HashMap,MySecondObject> is not NULL.
> I have simplified my example and I have the same issue with an HashMap of
> HashMap of SimpleInDataBean (composed of two String parameters).
> //KO
> public void
> manageHashMapOfHashMapOfSimpleInDataBean(HashMap<String,HashMap<String,SimpleInDataBean>>
> myComplexData);
> //OK
> public void manageHashMapOfSimpleInDataBean(HashMap<String,SimpleInDataBean>
> myComplexData);
> Here is the error stack trace I got:
> org.apache.cxf.aegis.DatabindingException: Couldn't instantiate class. null.
> Nested exception is java.lang.InstantiationException: null
> org.apache.cxf.binding.soap.SoapFault:
> org.apache.cxf.aegis.DatabindingException: Couldn't instantiate class. null.
