Error struct with Type Library and TestStand compatible

I have this struc

//ADDT Error

typedef struct Error
{
int code;
char *msg;
int occurred
}Error;

I generate a front panel automatically  from my .h and the help file and I integrate it in a Type Library but when I call it to TestStand I get a warning saying "Parameter x is an unsupported type. The type will be default to integer".

The help in TestStand is active as I intended.

I have already tried separating the error handling function and load the library and generate the .fp adding the .h instead of the type individually with ///ADDT Error.

I must say that when I configure the type manually to struct and Error in TestStand it works but am I doing something wrong? 

The type library is supposed to do this automatically right?
