CEdit may not handle variable vent openings with only one input

[rpeacoc]

From a discussion group user:

I have encountered a potential issue with time-based vent openings. This issue appears in both CFAST 7.7.1 and 7.6.0 (which I was running comparisons against) and occurs with a single or multiple compartment-to-compartment vents.

It seems that if only one Open/Close Criterion Table entry is entered in using the CEdit GUI, the program doesn’t factor the input into the calculation and doesn’t save the input to the .in file.
I can get the input to be reflected in the model and saved in the .in file by duplicating the desired value into the Open/Close Criterion Table (i.e. two identical rows for time and opening fraction).
Also, if I manually open the .in file in a text editor and enter in just one table entry, the model will run correctly and save the input in the .in file.
I could not find text in the user’s manual or technical reference to indicate duplicate entries are required.
