Warnings within standard BuildInDS sample

[Developer12145]

Hi Isomorphic,

Setup:
SmartClient Version: v12.0p_2020-03-11/PowerEdition Deployment (built 2020-03-11)
Google Chrome Version 79.0.3945.130 (Offizieller Build) (64-Bit)

I get some warnings in the Developer Console with a fresh installed BuildInDS. I didn't modify anything, so you can just use the normal BuildInDS-sample.

1. select "Animals" as datasource
2. Right-click on the header-menu of the Grid
3. deselect Animal, Scientific Name, Life Span, Endangered Status, Diet
4. select additionally Pictures
5. Click outside of the Grid and then hover with the mouse from left to right over the header-menu of the Grid. You receive the following warnings:

*17:19:26.961:INFO:Log:initialized

*17:19:37.555:MUP1:WARN:DynamicForm:isc_DynamicForm_0:saveData() called on a non-databound DynamicForm. This is not supported.  for information on databinding of components look at the documentation for the DataSource class.  If this was intended to be a native HTML form submission, set the canSubmit property to true on this form.

This affects our application as well.

Thanks for having a look,
