Symptoms
List View text cut off in a specific column.
Diagnoses
The mouseover text was truncated as well, which pointed to the fact that the source data might be the issue and not the display. Looked at the SQL column type behind the column and it was set to nvarchar(20), which would cut off the sampled text.
Resolution
Scripted a 'drop and create to' on the table, increasing the nvarchar value, refreshed the service instance, published a new SmartObject with the same name, category, and GUID as the previous one.
