Topic: Unable to resolve discriminator in definitions
Patrick Werner (May 14 2020 at 10:45):
In the CG IG we have the following discriminator on Observation.derivedFrom: Slice: Unordered, Open by type:resolve(), pattern:resolve().code

Patrick Werner (May 14 2020 at 10:47):
We want to discriminate by type as derivedFrom can be an Observation or a MolecularSequence, pattern:resolve().code is used to discriminate the different Observations
Patrick Werner (May 14 2020 at 10:48):
When trying to validate examples against the profile we are getting: Error @ Bundle.entry[9].resource.ofType(Observation).derivedFrom[0] (line 428, col14) : Unable to resolve discriminator in definitions: code
Patrick Werner (May 14 2020 at 10:53):
For the slices we added Pattern like: {"coding":[{"system":"http://loinc.org","code":"69548-6"}]}

But these patterns aren't applied to the slices by the IG publisher.

do you want to make a validator test case? (valid and invalid examples, and profile)
Patrick Werner (May 14 2020 at 11:20):
will do

do you think the content in the pattern column is correct? Was not sure if can do a pattern like this on a reference.
Grahame Grieve (May 14 2020 at 11:31):
looks ok to me
Rob Hausam (May 14 2020 at 13:51):
@Grahame Grieve @Patrick Werner Is Open by type:resolve() somehow valid (or is that just a typo)? As far as I know, slicing.discriminator.type must be "value | exists | pattern | type | profile".
Patrick Werner (May 14 2020 at 13:55):
thats how it is rendered, in JSON:
"slicing" : {
"discriminator" : [
{
"type" : "type",
"path" : "resolve()"
},
{
"type" : "pattern",
"path" : "resolve().code"
}
],
"rules" : "open"
}
Rob Hausam (May 14 2020 at 13:58):
OK, yeah. Never mind. It looked strange to me for some reason when you posted that - but I have the same in my IG - except that I use $this.resolve() as the path. :)
Rob Hausam (May 14 2020 at 14:01):
Sometimes the double use of 'type' can be confusing (particularly if you read it wrong!).
Patrick Werner (May 14 2020 at 15:19):
oh yes!
