Ciao,

i work to port some code from Pharo 4.0 to Pharo 6.1-64.

My root class into Pharo 4.0 define the properties

instance variable and some relative method:

a) propertyAt: aKey ifAbsent: aBlock

^ self properties at: aKey ifAbsent: aBlock

b) propertyAt: aKey ifAbsentPut: aBlock

^ self properties at: aKey ifAbsentPut: aBlock

c) propertyAt: aKey put: aValue

^ self properties at: aKey put: aValue

d)......

Now when i port this code into the Pharo 6.1-64 when compile the code

the Behavior originalName method implement:

^ (( self isObsolete and:[ self name beginsWith: 'AnObsolete ............


where isObsolete   TClass   is:

self propertyAt: #obsolete ifAbsent: false


But my class implement a specific propertyAt: ifAbsent:   method

and the system generates errors and  don't compile the code.


Thank you for every consideration.

Dario
