Hi All,
on 10.2.8, NSPasteboard's read/write method pair for propertyList has
a serious problem about NSDictionary
which has NSDecimalNumber type value.
NSDecimalNumber value cannot be retrieved correctly through pasteboard
using this method pair.
The same problem about NSDecimalNumber value can be seen in
NSPropertyListSerialization itself
pList = [self getPList];
data = [NSPropertyListSerialization dataFromPropertyList:pList
format:NSPropertyListXMLFormat_v1_0
errorDescription:NULL];
string = [[[NSString alloc] initWith
Data:data
encoding:NSUTF8StringEncoding] autorelease];
NSLog(@"string = %@",string);
XML format property List is
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"
http://www.apple.com/DTDs/PropertyList-1.0.dtd";>

and
pList2 = [string propertyList];
NSLog(@"pList2 = %@",pList2);
<CFDictionary 0x1464640 [0xa01303fc]>{type = mutable, count = 6,

)}
I guess somewhere of NSDecimalNumber is broken.
and more ....
in the case I am testing ...
other side pair method call will casue a termination by signal
10(SIGBUS)
in CFPropertyListCreateFromXMLData.
// string = [pb stringForType:NSStringPboardType];
// NSLog(@"string = %@",string);
string = .... the same one ...
data = [string dataUsingEncoding:NSUTF8StringEncoding];
// this test app will crash in the next methd call
pList = [NSPropertyListSerialization propertyListFrom
Data:data
mutabilityOption:NSPropertyListImmutable
format:NSPropertyListXMLFormat_v1_0
errorDescription:NULL];
NSPropertyListSerialization doesn't work well with NSDecimalNumber.
