LabVIEW Crashes When Converting Flattened "Lines" Refnum Back to Variant

Issue Details

I am converting a "lines" (ULxIORefnumTag) refnum using "Variant To Flattened String" and when I try to convert it back with "Flattened String to Variant" LabVIEW crashes with no error message. I also see a coercion dot on "Variant To Flattened String".

Solution

Use string controls instead of "lines" (ULxIORefnumTag) refnum, or typecast the "lines" (ULxIORefnumTag) refnum to string before wiring it to "Variant To Flattened String".
