I have solved the issue PARTLY.
My NSData issue seems to have been resolved, and that was my mistake
so I will no go into it.
Now it appears that I can convert the MailMessage to NSData and save
the data and read the data on startup. However if I try to convert
this Data to a MailMessage as the data is being initialized by calling:
[ NSKeyedUnarchiver unarchiveObjectWithData:messageData ]
I get the error. Could this be due to the Mail calls not haven't been
loaded?
Now if I save the data and try to do the conversation at runtime then
I dont get the error, but the pointer to the MailMessage that I get
back does not seem to be the original pointer that I had saved. If I
try a test and at the time that I read the MailMessage, convert it to
an NSData and then immediately convert it back it works fine, however
if I try it in another call even without restarting the app I get a
different MailMessage data.
This is the descriptor that I get when I first create and convert the
MailMessage
<MailMessage @0x1a800510: <class 'mssg'> id 36371 of <class 'mbxp'>
"INBOX" of <class 'mact'> ".Mac" of application "Mail" (15594)>
and this is the descriptor when I try it from another call
<MailMessage @0x63b4e0: application "Mail" (15594)>
Any help!!!
Thanks

Hi all
I am trying to save a MailMessage that I obtain from Apple Mail
using scripting bridge.
I get the message and I check to see if it does conform to NSCoding
protocols, which it does.
[ message conformsToProtocol:@protocol(NSCoding)]
then I go to encode it in my encodeWithCoder call
- (void)encodeWithCoder:(NSCoder *)encoder
{
[ encoder encodeObject:message forKey:@"message" ];
}
that works fine, but when I go to decode the object I get the
following error:
exception raised:*** -decodeObjectForKey: only defined for abstract
class. Define -[NSKeyedArchiver decodeObjectForKey:]!
I even tried to convert the message object to NSData and then encode
it:
- (void)encodeWithCoder:(NSCoder *)encoder
{
NSData *data = [ NSKeyedArchiver
archivedDataWithRootObject:message ];
[ encoder encodeObject:data forKey:@"message" ];
}
however still I get the same error when trying to decode the data
NSData *returnData = [ encoder decodeObjectForKey:@"message" ];
Thanks
