Using FT Linx Gateway for the UA Server. When reading a null string, the tag quality is fine. When binding a property like the Label.Text the Label.Quality is “Error_TypeConversion.”
Accessing the same UA server with 7.9.9 has no error. Using Ignition UA Server has no error.
Populating the tag so that it is not null also makes the error go away.
I am having the exact same issue after upgrading to 8.0.2 from 7.9. Big Red X’s all over the screen anywhere the PLC tag string length = 0. Adding a space to the blank strings (LEN=1) fixes the issue.
