Description cadorca 2008-02-16 21:32:38 UTC 
when I try to use a List of objects as source for a visualweb table the IDE always generate a
java.lang.ClassNotFoundException for any object

Steps to reproduce:
1. Create a new visual web project
2. Create or Import some entities
3. Create a method that return a List<Some Object> for example public List<Customer> getCustomers(){ return new
LinkedList<Customer>();}
3. Add a table to the page and select the  customers as source

Comment 1 _ sandipchitale 2008-02-19 22:50:34 UTC 
For the fix for issue # 125081 ModelSet$ProjectClassLoader memory leaks the 

ClassUtil.getClass(typeName)

implementation now expects that the Thread's context Classloader is
set to the Project Classloader. The call in the BeansDesignBeanExt missed
setting it before calling ClassUtil.getClass(typeName). That resulted in:

java.lang.ClassNotFoundException
