sorry for bugging again on this, unfortunately there still is a case where the
lazy loader fails ;(
When classes have not the default empty constructor, CGLIB complains
{code}
java.lang.IllegalArgumentException: Superclass has no null constructors but no
arguments were given

at
org.apache.commons.digester3.Digester.startElement(Digester.java:1350)
{code}
you can test it simply by removing the empty constructor in
{{org.apache.commons.digester3.TestBean}}
Thanks a lot for your help in advance!

Project: Commons Digester
Issue Type: Improvement
Affects Versions: 3.2
Reporter: Simone Tripodi
Assignee: Simone Tripodi
Fix For: 3.2
As shown in the past, the stack method of Digester has some [limitations
|http://markmail.org/message/wick27gw6n5weqk2] for fully support the
Constructors - it basically cannot use elements in the body as constructor
arguments - but it could support arguments extracted from attributes.

Unfortunately the LazyLoader still fails under certain circumstances: imagine
an XML snippet like:
{code}
toplevel
bean double=9.99
booleantrue/boolean
float5.5/float
/bean
/toplevel
{code}
and the mapped bean is of the type
{code}
class MyBean
{
private float floatProperty;
public MyBean( double doubleProperty, boolean booleanProperty )
...
}
{code}
what happens is that not all constructor parameters are correctly collected
because the object is created in the {{begin()}} method when {{toplevel/bean}}
matches.
I don't know at that oint if it is possible creating a Stub that simply
collects methods that can be called when invoking the {{end()}} method when
{{toplevel/bean}} element is closed...

I just thought that using CGLIB to proxy Object creation, the
{{ObjectCreationRule}} would fully support arguments coming from everywhere.
Need some time to give tries.
