Sorry to resurrect an older topic, but this thread was almost exactly my issue, and I still have a few questions.
I’m on Ignition 8.1.7 and am getting lots of “Invalid Key” warnings in Designer. Thanks to this thread, I’ve narrowed it down to object keys that have spaces in them or start with numerals (0-9). In my case, they are the column names for the data of a Perspective table, so I have hundreds of warnings (e.g. 10 columns by 40 rows = 400 warnings).
One complaint I have is that Designer doesn’t seem to be highlighting which keys are causing the warning for me (most of the time). After working in Designer for 30+ minutes it randomly popped up the highlighting of bad keys once for me, and then I came back and noticed that they were also highlighted in the screenshots of this thread. But then my highlighting disappeared and hasn’t come back since.
My bigger question: will using with these invalid keys in a Perspective data table actually cause any issues other than the warning? I need the spaces and numerals in the column names since that’s how they need to be displayed, and the idea of dynamically building a
columns property just to map from “valid” key names to column names seems excessive. Everything seems to be working right now other than the warning.
