Question

Mapping InfoTable property returned from a query service to a Widget (Grid/Chart)

Hello All,


I am trying to create a dynamic mashup that changes its contents based on the Thing selected. Use case is basically:


Query Things that contain a certain property value;

Populate mashup widgets based on the Selected Rows returned by the service.


This approach is working well to populate Labels and Single Fields, but when I try to populate a chart from an InfoTable property it returns empy values. I tried also to populate a GRID with the selected values and it still returns nothing.


Here is a screenshot for my connections: https://dl.dropboxusercontent.com/u/56013581/PopulateWidget.jpg


Anybody knows what I could be doing wrong?


Thanks

Ewerton

    Just noticed an error in the log, but still did not figure it out:

    After speaking with Adam I realized that what I was trying to do is not supported. To work around I just encapsulated the code in a service that returns an Infotable:

    var result = Things[ThingName].SensorReading;


    ThingName is an inputParameter

    SensorReading is an Infotable property that stores sensor readings.


    Thanks Adam for the help!
