Subscription on a Multi-Instance Attribute #637

Closed AHABID closed 7 months ago

AHABID commented 2 years ago

We have tried to create a subscription on a specific instance of a property using the NGSI-LD query language as follow:

"q":"propertyName.datasetId==\"urn:ngsi-ld:Dataset:01\""

The subscription is created, but when updating the concerned instance of the attribute we are not reciving any notification. On the subscription entity the "timesSent" is 0 .

Until #1144 is done, this can be achieved by specifying instead:

"q":"propertyName.datasetId==urn:ngsi-ld:Dataset:01"
