Hi everyone,
I've spent most of the past three weeks in great distress as I try to
isolate a bug that is causing my standalone to lose data.
I think I have finally isolated the bug into a demonstration stack with
the title: "myBuggyApp" and I have uploaded it to my user space (user
name= 'michaelbinder') on rev online.
The bug (or my programming error) only manifests itself in a standalone.
I used the data saving method described by Sarah Reichelt in
revJournal, in which substack "dataTemplate" is cloned to make a data
file.
In myBuggyApp demonstration, the user data is validated and placed into
custom properties of a custompropertyset of the dataTemplate substack.
When I save data to an existing data file, I use this code:
-- the variable 'whichFile' contains the file path of the
-- user's data file
open invisible stack whichFile
set the custompropertyset of stack whichFile to "allDataProps"
set the customproperties["allDataProps"] of stack whichFile \
to the customproperties["allDataProps"] of stack "dataTemplate"
save stack whichFile
close stack whichFile --the destroystack of stack whichFile is true
In the big complex app that I have been working on, I do have a
workaround. I simply repeat this line twice:
set the customproperties["allDataProps"] of stack whichFile \
to the customproperties["allDataProps"] of stack "dataTemplate"
I have no idea why the workaround works. One source of distress to me
is that the workaround DOES NOT work in the demonstration stack.
Before I report this bug I would like to know if it is indeed a bug, or
have I made a programming error. If it is a bug do any of you
understand its nature or how to make a reliable workaround?
Thanks, in advance, for your comments...
Michael Binder
