Hi,
I recently set up Thingworx 8 locally. I imported the MQTT Extension from the marketplace and experienced strange behaviour that didnt happen in Thingworx 7.
1. A property of a MQTT-Type Thing publishes its value when it changes even if the property is only mapped as subscriber to a topic
2. I use a subscription script to update other properties depending on the JSON values of the subscriber property. This script subscribes to the datachange event. It fires and works ok if I update the value manually but fails if the property value is updated by MQTT.
The error in the log is as follows:

The Code of my subscription is the following:
var decodedValue = eventData.newValue.value;
var createITParams = { infoTableName : "InfoTable", dataShapeName : "NamedVTQ" };
var properties = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(createITParams);
//Max Displacement Update
var row = new Object();
row.name = "MaxDisplacement";
row.value = decodedValue.max_displacement;
row.time = decodedValue.timestamp;
properties.AddRow(row);
