Ciao,

�� i works with Pharo 4.0 environment.

�� I have a class Product�� with some instance variable and the�� =�� method set to:

�� = anItem

�� anItem ifNil:[^false].

�� anItem class = self class ifFalse:[ ^false].

�� ^�� rfrConsegna�� = anItem rfrConsegna
�� and:[ rfrSubTable�� = anItem rfrSubTable
�� and:[ rfrDcm = anItem rfrDcm
�� and:[ indexRiga = anItem indexRiga
�� and:[ referenceTime = anItem referenceTime
�� and:[ consumer = anItem consumer
�� and:[ item = anItem item
�� and:[ opzioniVoce�� = anItem opzioniVoce
�� ]]]]]]]

�� Some of these variables are instances�� of classes with specific implementation and some variables themselves.

�� I set the relative hash method to:

�� hash

�� ^ rfrConsegna hash
�� bitXor:( rfrSubTable�� hash
�� bitXor: ( rfrDcm hash
�� bitXor: ( indexRiga hash
�� bitXor: ( referenceTime hash
�� bitXor: ( consumer�� hash
�� bitXor: ( item�� hash
�� bitXor: ( opzioniVoce�� hash

�� )))))))

�� Now when add some setup instances of class Product�� to a bag,

�� the relative inspector report

�� some aProduct entry but with some Occurences of this set to 0.

�� aProduct1�� 3
�� aProduct2�� 0
�� aProduct3�� 0

�� Some consideration about it ?

�� Some references about hash implementations ?

�� Thanks,

�� Dario
