Live tiles not updating on streaming dataset

[njrandell]

I've been having issues getting streaming datasets to work reliably and consistently. I've created a github repo https://github.com/sceneskope/powerbi that has an example of the problem.

The Samples/StreamingSample project runs correctly and writes data every 5 seconds with no errors. I can see the dataset and all the counters, but the data is empty.

Is this something I'm doing wrong? I can't see any error messages.

Thanks

I've identified this issue. I was using the Camel Case Converter in the Newtonsoft Json library, and it was sending the columns with the first character in lower case. In this situation the streaming service didn't recognise the column, whilst the push service did.

Changing my code to not use the Camel Case Converter and it all started working ok. I guess this is a documentation update, but is also an inconsistent behaviour between the push and streaming services.

One other thing I noticed is that the Streaming service does not support measures. Not really an issue, but would be good to make sure the documentation mentions this.

Could you please provide a fiddler trace for this issue? You can start the trace before create the live tile, and share the saved .saz file to us through online file service like OneDrive.

To add a bit more information. I've added examples to do PushStreaming as well. Very much the same results.

I can however get a chart to appear on a dashboard by creating a report and then pinning a tile from the report to the dashboard.

This shows data is flowing in, but the individual live cards are not updating
