Hello everyone !

Andrus, thank you for fixing that bug so quickly !


I got another problem, it may be related to previous thats why I post  
it here.

It does not happen always, I tried to create a separate project to  
reproduce it, but I couldn't.

This is the code which reproduces problem in my application:

				CayenneContext context = ContextManager.getNewDedicatedContext();
				List students = context.performQuery(new SelectQuery 
(Student.class));
				for (int i=0 ; i<students.size();i++) {
					Student student = (Student)students.get(i);

					//this works ...
					logger.info(i+ ") students count = " +student.getLanguage 
().getStudents().size());
					
					//this don't work
					logger.info(i+ ") language name =  " +student.getLanguage 
().getName());
				}
				
				CayenneContext context2 = ContextManager.getNewDedicatedContext();
				List languages = context2.performQuery(new SelectQuery 
(Language.class));
				for (int i=0 ; i< languages.size();i++) {
					Language language = (Language)languages.get(i);
					if (language.getStudents().size() > 0) {

						logger.info(i+ ") language name =  " +language.getName());
						logger.info(i+ ") students count = " +language.getStudents 
().size());

						for (int j =0;j<language.getStudents().size();j++) {
							Student student = ((Student)language.getStudents().get(j));
							logger.info("\t"+j+ ") student name = " +student.getFullName());
							logger.info("\t"+j+ ") student language = "  
+student.getLanguage().getName());
							
						}
					}
				}

On output I'm getting :

   - 0) students count = 1
   - 0) language name =  null
   - 1) students count = 1
   - 1) language name =  null
   - 2) students count = 1
   - 2) language name =  null

  - 8) language name =  Galic
  - 8) students count = 1
	  - 	0) student name = test test
	  - 	0) student language = Galic
  - 1287) language name =  Guatamalan
  - 1287) students count = 1
	  - 	0) student name = test2 test2
	  - 	0) student language = Guatamalan
  - 1509) language name =  English
  - 1509) students count = 1
	  - 	0) student name = test3  test3
	  - 	0) student language = English

It looks like sometimes the object is not "faulted" correctly. I  
can't see when and why ...
