Let's follow up this discussion at the Neptune Community
(this forum will be kept in read-only mode)
The field size of attribute values ist restricted to 100 characters.
I request to enlarge this field to at least 255 characters.
My example below shows concatenated binding (all fields used in a complex formatter). The string gets truncated, browser source breaks.
Workaround: shorten attribute names
But this really is a nasty workaround, and not a solution to live with.
