This expresion returns null even though there is Table called "LiniItems" with at least 4 fields:
GetValue(FieldNames ( Get(FileName) ; "LineItems");4)
The backround is that the table was created, deleted and recreated, but the calc engine can't get to grips with that.
If I change the table name to "LineItems2" and refrence that name it works fine. Change the name back -- fails again.
Is it just me or can anyone reproduce this? (FMPA12, Mountain Lion)
