"Child" Table Widget fails to render the content of an array
I've been following a vacation example to implement a living app page with the following UI using Community Edition (v. 7.5.4):
- there is a top-level table with main contents
- when user clicks on the top-level table row and selects it, the row details are rendered in a separate container.
Then, in the row details I need to display additionally an array of other child objects (activities) - also in a table widget.
However, this "child" table fails to render: most of the columns not displayed, a single value in column 'visible' appears though it's supposed to be 'YES'.
