How to set Default Values to Infotable properties to Thing shape through Programatically?

Hi @vi1 ,

I tested in TWX 9.1.3 and 9.3.2 with below code and it seems I could pass default value with Infotable Type data to AddPropertyDefinition service successfully and the property created at ThingShape level with default value set without any issue.

// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(WeatherDataShape)
let a = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape({
 infoTableName: "InfoTable",
 dataShapeName: "WeatherDataShape"
});

// WeatherDataShape entry object
let newEntry = {
 id: 1,// NUMBER [Primary Key]
 date: undefined,// DATETIME
 max_temp: 33,// NUMBER
 min_temp: 22,// NUMBER
 cold: undefined,// BOOLEAN
 visibility: undefined,// INTEGER
 wind: undefined,// LONG
 events: undefined,// STRING
 image: undefined,// IMAGELINK
 location: undefined,// LOCATION
 actions: undefined,// HTML
 info: undefined// HYPERLINK
};

a.AddRow(newEntry);

ThingShapes["testThingShape"].AddPropertyDefinition({
	defaultValue: a /* STRING */,
	remoteBindingAspects: undefined /* JSON */,
	description: undefined /* STRING */,
	readOnly: undefined /* BOOLEAN */,
	type: "INFOTABLE" /* BASETYPENAME */,
	remote: undefined /* BOOLEAN */,
	remotePropertyName: undefined /* STRING */,
	timeout: undefined /* INTEGER */,
	pushType: undefined /* STRING */,
	dataChangeThreshold: undefined /* NUMBER */,
	logged: undefined /* BOOLEAN */,
	name: "test2" /* STRING */,
	pushThreshold: undefined /* NUMBER */,
	dataChangeType: undefined /* STRING */,
	category: undefined /* STRING */,
	persistent: true /* BOOLEAN */,
	dataShape: "WeatherDataShape" /* DATASHAPENAME */
});

The only problem is that the service requires the same property name does not exist in advance. It cannot update existing property and set a default value to it.

Another workaround I guess is to use ThingShapes["xxx"].GetImplementingThings(); to get a list of instantiated things, loop through the entity list and update property values - this should have the same effect as setting default value at ThingShape level.

Hope that helps.
