The test.. testDictionaryKeys | dad | dad := self manClass testPerson save. kid save. mom children: (Dictionary with: dad -> kid). mom save. self flushAndReload. self assert: (mom refreshed children at: dad refreshed ) equals: kid refreshed Should have already covered this scenario to ensure other records work as keys. #flushAndReload is the same process that happens during image startup. Could you possibly express your scenario as a failing test like above using the existing mock objects? If you can show me a failing test I'll get the problem resolved much quicker. -- Ramon Leon http://onsmalltalk.com

SandstoneDB and a dictionary

by David Zmick

Saving a dictionary that has references to other objects as keys results in data loss in the dictionary. I have created a simplified example to explain my problem: SDActiveRecord subclass: #Test instanceVariableNames: 'as bs' classVariableNames: '' poolDictionaries: '' category: 'Sandbox' Test>>initialize super initialize. self as1: OrderedCollection new. self bs: OrderedCollection new. self as add: (A new title: 1). self as add: (A new title: 2). self as add: (A new title: 3). self bs add: (B new title: 1). self bs add: (B new title: 2). self bs add: (B new title: 3). self as do: [:a | self bs do: [:b | a dict at: b put: 1]]. Object subclass: #A instanceVariableNames: 'title dict' classVariableNames: '' poolDictionaries: '' category: 'Sandbox' A>>initialize self dict: Dictionary new. Object subclass: #B instanceVariableNames: 'title' classVariableNames: '' poolDictionaries: '' category: 'Sandbox' Evaluating Test new and inspecting the result behaves as expected, but after evaluating Test new save, verifying the Test findAll has the expected values (which it does) and closing the image without saving, opening the image and attempting to reload the objects results in each instance of A's dictionary looking like this. dict: a Dictionary(nil->1) it should have said this(and did before closing and opening the image again): dict: a Dictionary(a B->1 a B->1 a B->1) Hopefully I have explained this problem somewhat well, it is difficult for me to find any other way to explain what I am experiencing. Should I not be using the B objects as dictionary keys? Am I using the wrong dictionary? I am lost. Thanks for any help. -- David Zmick dpzmick(a)gmail.com
