Description

If the child collection is an indexed list when you edit a child object and go back to its parent the object gets added to the list twice, in fact is more than twice, it gets added to the list every time you edit it.

This bug does not affect Trails 1.0 or Sets, and if you are using a non indexed list the bug may not seem too big.

To see the bug in action, lunch the "simple" example, edit a catalog and then add categories to it.

a workaround (from the user's point of view) is to use an "add" method

public void addCategory (Category category) {
		if (!getCategories().contains(category)) {
			getCategories().add(category);
		}
	}

Trails will automagically detect that this method exists and it will use it for adding child objects to the collection.
