Hi everyone!
I'm working on a Core Data-based document application. It works with
individual sets of data that can be added or deleted from the saved
file by the application. The method for adding these sets is
arbitrary for this question.
Essentially, this question stems from the fact that sometimes when the
document is saved, it results in a blank file. I believe this only
happens when the document is saved and nothing has been changed.
Since document saving works correctly when a data set has been added
or deleted, and that the file is saved using the traditional, default
methods which Apple provides in the initial source code (populated
when creating the application) I am very unsure as to where to proceed
from here. So, has anyone else experienced a problem similar to this
and/or how might I go about fixing this?
To clarify from prior postings, my problem differs from http://lists.apple.com/archives/Cocoa-dev/2006/Jul/msg00262.html
as it does save a populated xml file initially and any subsequent
time in which the data has been changed.
In addition, I have ensured that it is not simply a problem with
populating the table. It is, in fact, a file saving issue.
Any help would be great,
Dave
