I've been careful to create separate versions of my stack files and
Livecode Preferences folder for use when running LC 7. However, it seems
there other issues with compatibility.
I save the preferences for my application in a file in the
/Library/Application Support folder with the following statement:
*write* base64Encode(arrayEncode(gSettings)) to file <filepath>"
These are then read in at startup with:
read from file myPath until EOF
if it is empty then
put empty into gSettings
else
put arrayDecode(base64Decode(it)) into gSettings
end if
Yesterday, I started working on this stack with LC7 and the prefs file was
saved by the LC7 version of the stack.
Today, I needed to go back to the non LC7 version of the stack. To my
surprise, a runtime error was thrown on the "put arrayDecode..." statement
above. The it variable looked like it contained base64 encoded data.
I ran the LC7 version of the stack again and the runtime error did not
occur.
I restored the preferences file from a Time Machine backup that I know
preceded my use of LC7, ran the application again with LC 6.6.2, and all
worked fine.
So it seems that something in either the array/base64 encode/decode
functions changed between v6.6.2 and 7.0.1.
I really want to use LC7 but stuff like this makes me very nervous. How
many other inconsistencies like this are lurking out there.
