I probably need to send a bit more info.
My latest attempt was this:
mapper := NeoJSONReader new.
mapper for: #RootObject customDo: [:mapping | mapping mapWithValueSchema:
#TransferMessage].
mapper
for: #TransferMessage
do: [:mapping |
(mapping mapInstVar: 'Data' to: 'Data') listOfElementSchema:
SomeExistingSmalltalkClass].
which results in
Symbol does not understand allInstVarNames
Please note there is no class named #TransferMessage in my Image. This
works for things like #ArrayOfPoints in the examples on the NeoJSON git
page and it also works in some of my other JSON mappings in different
contexts.
I guess this is because I cannot map to instvars if there is no
class/object to store values into...
So do I really need to implement an otherwise useless Smalltalk class
just to have something to map the outermost {} object to?
I also tried variations of for:customDo: for the mapping of the
#TransferMessage and had no success so far.
Any ideas?

Hi there,
I am having a hard time configuring a NeoJSONReader for a JSON file
like this:
{
"Paging": { someStuff
},
"ErrorMessage": null,
"ErrorCode": 0,
"Data": [
{object1},
{object2}
]
}
Where I want to ignore everything but the list named "Data". (Of
course I'll have to take a look at ErrorMessages later, but one step
after the other...).
I've tried several combinations of mappers and always end up with
NoeJSON parsing Exceptions. I semm unable to see the obvious.
In The end I just want to only use the contents of the Data list and
map each entry in there to some smalltalk object. I was successful
with other structures and lists, but this time I am unable to see the
forest among all those trees.
Any hints?
Joachim
