Appendix 10 - Point Manager - Missing Discovery Point Icon

Q. In the point manager, why does might discovery object not have an icon next to it?

A. A discovery object will not receive an icon next to it in the point manager if the discovery leaf's 'getValidTypes' method returns null or an empty array.

Solution: Review the 'getValidTypes' method of the corresponding discovery leaf class in the driver and ensure that it returns an array of TypeInfo. The TypeInfo entries in the array should correspond to standard Niagara AX control point types. The TypeInfo entry at location zero is the default database type. The discovery object's icon will be selected based on the default database type.
