Nobody having problems with NS(Decimal)Numbers and property lists?
I have an NSTable that displays formatted real numbers (cells have an
NSFormatter attached).
I initially saved my data structure, an NSDictionary with a key
indexing an NSArray of NSDictionaries (= the table) with
writeToFile:atomically:.
Everything used to work fine with Mac OS X 10.1 and the previous
release of Dev Tools.
Under Mac OS X 10.2.3 and with Dec Tools I have the following problem:
when I open again a previously saved file, numbers are not displayed.
Numbers are NSDecimalNumber.
I fixed this by archiving (NSArchive) my data structure before saving,
but I still have problems. I have implemented copy and paste and drag
and drop among different tables. I write selected records on the
pasteboard with
[pboard setPropertyList:arrayOfSelectedRecords forType:@"my Type"];
where arrayOfSelectedRecords is an array of NSDictionary whose fields
are NSDecimalNumbers.
Again, under Mac OS X 10.1 everything worked fine, but now numbers are
not displayed when pasted.
Please help me, because this is somewhat frustrating. Should
NSDecimalNumbers be property list objects, in that they are a subclass
of NSNumber? Or am I assuming something wrong?
Thanks in advance
