When running the "Altia PhotoProto - Build Prototype" script, you might see a popup dialog with "Error: The requested property does not exist."
This is due to an issue in Adobe Photoshop. The Photoshop Scripting DOM (Data Object Model) does not create properties for certain attributes of layers if it has not been explicitly changed by the user.
Altia PhotoProto 2.1 has a built-in error catch for Text color (it assigns it black instead of spawning an error), but the font name can still cause this error.
This can be easily fixed by following the steps below:
1) Select the Text layer from which the error spawns (the layer the script stops on).
2) Change the font name to something else using the Character palette.
3) Change the font name back to the font you intend to use for your Text object.
