Differences between Field Visualization on a Form and in a List component

• For List components you do not necessarily need to open the Field Component source.
• When used on a form a field visualization will always have a corresponding class in the Field class list.
• When used in List components visualizations are chosen through the properties of the column (eg DisplayAppearance, EditAppearance).

The concept of field visualization in list type components can get somewhat confusing as the full set of Field Visualization options are available on a column regardless of the field being sourced to that column. This can easily lead to incorrect results for inexperienced users. (eg. It is possible via a Columns properties to try and Visualize a field as an ImageSet even though you may not have defined the available images for the field by adding a picklist and items in the field source).

To avoid the pitfalls of using Field Visualization in the LANSA List components it is advised that you take the provided sample that is the closest match to your requirements as a starting point. This will then be easy to modify.
