Re: subscription example.. Integer_Array

[Ricardo Aguirre]

I have a doubt,
I'm not really skilled using ada, and now I have some problems.
 
I just want to publish a  simple integer_Array that contain 3 integers values (1,2,3)
Theorically it should work but I get arange check failed
Can you give a hand?
I don't understand really well ada generics, and I lost a complete day...
This is my code:

And this is what I get:

Thank you

In the current YAMI4 version it is not possible to create an array of
nested Parameters objects. This functionality might become part of
some future release.

Currently the workaround for this is to express the same data in a
different data structure that does not depend on arrays of Parameters.

That's right - YAMI4 does not use any static description of data
structures.
Please check the following article for some explanation:

Just as the compiler says:

frame_publisher.adb:92:43: warning: value not in range of subtype of
"My_Index_Type" defined at line 52
frame_publisher.adb:92:43: warning: "Constraint_Error" will be raised
at run time

What you have in line 92 is:

Ada.Text_IO.Put_Line ("Ball_PositionX " &
My_Int_Type'Image (Position2(0)));

and the type definitions are:

type My_Int_Type is new Integer;
type My_Index_Type is new Positive;
type My_Int_Array is array (My_Index_Type range <>)
of My_Int_Type;

This means that indices in your array are positive numbers and you use
0. Try 1 instead if you mean the first array element.

Please note that this is not the YAMI4 problem and it does not really
belong to this discussion group.

I can't belive it!
I feel really really stupid

Thank you men
