PROPERTY UnknownVariable : STRING
This property returns only a non-empty string if the loaded trace configuration contains a variable, whose address info cannot be determined. We have the two cases: 1.) For a local application: The IAddressResolver instance was unable to resolve the address 2.) For a remote application accessed via datasource: The variable is missing in the datasource.
If more than one variable is unknown this property returns the 1st unknown variable.
