Question

Do the props on the Flexi Date Range Picker Mendix Widget persist?

0

When trying to export a Mendix object to JSON in React, an error appears about missing unique "key" props. While debugging this issue, I'm wondering about the behavior of Flexi Date Range Picker widget logging. Is it informational only, or do logged props get saved to the Data Source attribute at each step?

The React “missing key” warning is purely informational. The props logged by the Flexi Date Range Picker are not automatically saved to the Data Source attribute. The attribute is only updated through the widget’s onChange behavior, and it is written to the database only when the object is committed.
