5 years agoI have always used the first method, and it is actually documented to work unambiguously (until I checked, I thought perhaps it evaluated it and could be false if the value is 0). The exists() function says that it will check the values of all properties and is true if one or more have that value. I don't know when that would be useful :).
Function: exists("<property value>")
This function returns TRUE if the specified value is assigned to any of the resource’s properties.
Function: <property name>
Any property name can be referenced as an AppliesTo function. When used alone, it returns TRUE for any resource which has a value set for the specified property. It can be used with operators for comparison purposes.
