I have no problems using a custom property to change Label background and Label Font Size, but I´m not having success using the same property to change a Label Icon through Properties Mapper unless I place the full path to the icon.
Relative Paths are not working to define icon file position.
I have tested with the following formats: png, svg and ico. and the behaviour is the same.
I´m using a Node Configuration with no template and using Distinct Value for the conversion. Attached are my test file and used images.
I´m running Windows 10 Pro 1803 64 bits
