Hi people,

first of all sorry I my doubt has been answered before, I haven't found anything about it.

The thing is quite "simple", though, but I am not able to solve it



Code:
Category oldParent = currentCategory.getParentCategory();
oldParent.removeChildCategory(currentCategory.getName());
manager.update(oldParent);

parent.addChildCategory(currentCategory);
manager.update(currentCategory);


this is producing the following error:

I have tried doing a flush like this


Code:
public void flush(){
   SessionFactoryUtils.getSession(getSessionFactory(),false).flush();
}


between both operations

but that doesn't solve nothing at all, as it's generating another different error, this one:
