Ah, I overlooked that as well ;-) This could happen by STON input as follows { ... } : null with everything after the closing } being junk from a previous file that you overwrote with shorter contents.

David I think you are misreading the debugger display. The bit you are missing is the last few characters in the evaluation display, after the closing parenthesis. They should not be there if it is displaying a dictionary. Evidently the variable 'aDict' is in fact an association whose key is the dictionary and whose value is nil. I can't see where it goes from there, but I think you need to look more closely at the preceding line, FAOEntry>>getEntryObjectFrom:, and see what exactly it does with the junk in your .dat file.

Re: Problem with Dictionary and Associations

Thank you for that but it doesnât resolve my problem. Why does the stack move to an Association when doing the access to the dictionary? It is the Association indexing that fails as it wonât allow #entryAmount as a key. If I inspect the following code (STON fromString: result ) in the line ^ self makeObject: (STON fromString: result ) I get an Association. Why donât I get a Dictionary.

I can parse the file data you provided: STON fromString: '{#entryName:''Housekeeping'',#entryDate:Date[''2021-02-25Z''],#transactionID:''2021022501'',#entryAmount:-400/1s8,#entryCategory:''Housekeeping'',#entryDescription:''Housekeeping'',#match:nil}ousekeeping'',#match:nil}' "a Dictionary(#entryAmount->-400.00000000s8 #entryCategory->'Housekeeping' #entryDate->25 February 2021 #entryDescription->'Housekeeping' #entryName->'Housekeeping' #match->nil #transactionID->'2021022501' )" (BTW, this is STON not JSON). What I do see in the input is junk after the last } That can happen when you overwrite an existing file with shorter content. You should truncate such a file. >From your screenshot I can see nothing wrong, #entryAmount seems an existing key in aDict, that should just work. > On 11 Feb 2021, at 16:33, David Pennington <david(a)totallyobjects.com> wrote: > > I attach a couple of screen shots and a file containing the item that I am trying to open.
