So in your example above, the map would become:
$map := new collection("id" ;
->[Mail_Queued_Messages]ID; \\
"status" ;
->[Mail_Queued_Messages]Message_Sent; \\
"error" ;
"getErrorMsg([Mail_Queued_Messages]Message_ErrorCode)"; \\
"queued_on" ;
->[Mail_Queued_Messages]Message_QueuedDTS; \\
"last_sent_on" ;
->[Mail_Queued_Messages]Message_LastSentDTS; \\
"subject" ;
->[Mail_Queued_Messages]Message_Subject )
If you need to execute an expression within 4D (because it uses
commands not supported by Active4D), prefix the expression with "!".
Awesome!
Do I understand correctly that I need to use RowSets for this to work?
No, this is for use with a4d.json.addSelection, RowSets already have a
facility to use a column expression.
The Mail_ErrorText method is a 4D method. It calls a plugin method
and is accessed by 4D Client code too. So I need to call it like this?
"error" ;
"!Mail_ErrorText([Mail_Queued_Messages]Message_ErrorCode)"; \\
Correct.
The new version of the library is on the wiki.
Thanks! I'll download the new library version and give it a try. FWIW,
I was able to get it working using a RowSet based implementation.
best,
Brad Perkins
