Yikes. I should "try" to keep this simple. Do this:
put the defaultFolder into savedDefaultFolder
set the defaultfolder to defaultFolderForThisTask
... blah blah blah ...
set the defaultFolder to savedDefaultFolder
Then if you want to also set it back on errors, try 'try'. If you
don't want to tackle 'try', that is fine.
The problem with my simplified 'try' example above is that it ignores
any indication or handling of errors. It might be like this:
*************
try
put the defaultFolder into savedDefaultFolder
set the defaultfolder to defaultFolderForThisTask
... blah blah blah ...
catch e
error e
finally
set the defaultFolder to savedDefaultFolder
end try
*************
Except 'error e' is not a valid command. However, with recent change
in the IDE, this is not too bad:
*************
put false into bad
try
put the defaultFolder into savedDefaultFolder
set the defaultfolder to defaultFolderForThisTask
... blah blah blah ...
catch e
put true into bad -- throw is broken here
finally
set the defaultFolder to savedDefaultFolder
end try
if bad then throw "Error when loading external."
*************
It would be simpler if an error could reliably be thrown in the catch
section. Simpler yet if the catch could be optional:
*************
try
put the defaultFolder into savedDefaultFolder
set the defaultfolder to defaultFolderForThisTask
... blah blah blah ...
finally
set the defaultFolder to savedDefaultFolder
end try
*************
Now, that would be nice. (I'm assuming that hasn't been fixed when I
wasn't looking.)
