Setting a Report-level default Data Source does not affect new Components, as it should

[skyler]

Per the "Replace the data source for a component, page, or report" documentation,

"Setting a data source at the page or report level has no effect on existing components in your report. Instead, new components that you add use the page or report-level data source by default."

I understand the first part and it works as it is written. But the second part - about new components using the report data source - i just have not found this to be true. The steps I am following:

1. [Setup] Have two Data Sources, Data Source A and B
2. Create a new Report, connect to Data Source A (it will create a default component connected to A)
3. Immediately, go into File > Report settings and change the Data Source to Data Source B
4. Create a new component via the "Add a Chart >" button (for instance, a table)
5. If i understand the above, it should be using the Report Data Source, Data Source B. But this is where i see it is still using Data Source A. And changing the Data Source at the Report Level from A to B or vice versa does not do anything. The new components seem to still have local component data source settings rather than using the report default.
   
   

I was ultimately trying to get a workflow going where i could have a report built upon a single data source that i could easily go into the data source menu to change from A to B (prod to dev, for instance). I think I will need to find alternative methods that work at the component level (i.e., using Select > Charts with this data source on page) or use the Copy Report UI and use the "New Data Source" selector.

I was excited by the promise of what was written in the documentation, however. Is this functionality working as expected? Did i misinterpret the documentation?
