Re: [castor-dev] Error in Interface during marshalling

Hi Keith,

Here is my example with an interface. (the files are at the bottom of the mail)


"classA" implements "inter" 
"inter"  has this attribute : public static final int OBJECT_STATE_TO_CREATE
"classB" extends "classA"

My mapping file (jejeMappingNine.xml) defines :
* auto-complete="false" for "classA" (by default)
* auto-complete="true" for "classB"

When I marshall an instance of "classB", I get the following error :
org.exolab.castor.mapping.MappingException: Nested error: 
org.exolab.castor.mapping.MappingException: unable to introspect class 'pack9.classB' 
for auto-complete: The field OBJECT_STATE_TO_CREATE in class pack9.inter is not 
accessible -- the field must be public, not static and not transient

Thus, it seems that interface doesn't act as classes, in an auto-complete="true" mode. 
In classes, Castor uses public getter and setter. 
In interfaces, Castor reads directly the attribute and in my case, doesn't like my  
static attribute.
It would be great if, in an interface, Castor try to only marshall the attribute with 
a getter, as it does in classes.

Thank you very much.
See you

Opps...I didn't notice that you had it set to false...

Please share your example and I can take a look at it.
