11.1p / 12.0p sample fires 116 requests on load

[Blama]

Hi Isomorphic,

please see this sample in 11.1p (v11.1p_2018-08-23) and 12.0p (v12.0p_2018-08-23).

On load, they fire 116 fetch requests to the employees DataSource, where the approx last 100 requests return no data. I'm not sure this is on purpose.

What you're seeing is expected behavior. The TreeGrid is configured with loadDataOnDemand, so each fetch only returns the immediate children of the node being fetched. Since we don't know whether a node has any children before fetching, a fetch occurs for each leaf ... and returns no data.

That said, we'll consider making some changes to the sample to reduce the amount of fetching.

Hi Isomorphic,

I have been browsing the showcase (v12.0p_2020-03-28, Chromium 80 / Win 10) and noticed that this is still happening in the sample.

Previously the sample was only fixed for 12.1, but now it's fixed for 12.0p and 11.1p as well. You will see the sample fixed as of tomorrow's builds.

Hi Isomorphic,

I can see this is fixed in v12.0p_2020-04-03.
