Instantiation of wrong Classes if more the 1 class has the same name (within different packages)
------------------------------------------------------------------------------------------------

Key: CAY-521
URL: http://issues.apache.org/cayenne/browse/CAY-521
Project: Cayenne
Type: Bug

Versions: 1.2 [BETA]
Reporter: Ayhan Kondoz


Hello,

i found following bug in cayenne 1.2B1 and B2. I know that cayenne 1.1 did not have this bug.

I have 2 databases and in each database I have a table with the same name. The java classes for the nodes have different packages so the created java classes work fine and there is no conflict with multiple classes that have the same name. However when use a SelectQuery to get a list of objects from the database the returned list always contains objects from the same package so I get a ClassCastException when I try to cast them into the correct object. For Example


Database 1:
Table: mandant
Class: x.y.Mandant


Database 2:
Table: mandant
Class: x.z.Mandant


SelectQuery query = new SelectQuery(x.z.Mandant.class)

List list = context.performQuery(query);


Iterator iter = list.iterator();

while ( iter.hasNext() ) {
x.z.Mandant m = (x.z.Mandant)iter.next(); // ClassCastException
....
}


Further tests showed that the object within the list is an instance of x.y.Mandant instead of x.z.Mandant, hence the ClassCastException.

cheers
