I created a custom module using Module builder.
There is an image field "Thumbnail", I like to display in the list view. Since it is an optional field, and in case of its absence, I need to display a default image.
When I use ImageField with DefaultSrc pointing to the default image, only image I see in the list view is the default image. Even the content with thumbnail field populated, displays the default image instead:
What am I missing here? Does "DefaultSrc" attribute have a different purpose or use case than I am trying to accomplish?
