TypeError Problem

[jaye]

I am creating a custom save screen script and I am adding the location when saving a game. It works fine the initial save, then when you return to title it works. The problems comes when you refresh the game or close and open it again. When I do that the 'type error' message pops up. It says, "Can not read property of 'name' null." or "Can not read property of 'DisplayName' of null". The code I am using is:

$gameMap.displayName()

Totally guessing here...

Looks like you might be attempting to get a name before the map gets initialized (or at least the name variable hasn't been set).
Not sure about a real fix for your problem but have you ever looked into error trapping?
I think the Try Catch code block could help solve your issue.

Type Error
A TypeError is thrown if you use a value that is outside the range of expected types:

Example

var num = 1;
try {
    num.toUpperCase();   // You cannot convert a number to upper case
}
catch(err) {
    Console.log(err.name);
}

This might solve your issue:
Try using this...

try {
   $gameMap.displayName();
}
catch(err) {
    Console.log(err.name);
}

Instead of...

$gameMap.displayName();

This will catch the error but you still might not get the results you need.
Let me know if this helps at all. Again... a total guess.
