addarray index out of bounds

To improve performance i'm experimenting with the addarray method. But nomatter what i do i allways get an "array index out of bounds" error.

The (simple) experiment code looks something like

local ax, ay as array (of usual) //dynamic arrays

ax:={1,2,3) //create x-value array + data
ay:={4,5,6} //create y-value array + data
self:odcTC:series(0):addarray(alen(ax),ax,ay) //alen() returns the length of the array 1-based.

My programming language (CA-Visual Objects 2.7a) is using 1-based arrays and not (the usual) 0-based arrays (and yes i also tried Alen(ax)-1, 2, 3 etc.).
Now on some news-groups i read that there were some issues about this when passing arrays to delphi code.
I'm using the latest V5.

TIA
Jack

Hi Jack,

yes, you're correct, it only will work with 0-based arrays. In your case you will have to iterate through the Data Array and use the AddXY method to add the Data to the series.

Well, i tought this was the case.

Now, I read on some newsgroups where the same problems were discussed that it was possible to "change something" in the Delphi code in order to read the 1-based arrays.
Is this true (and if so, would this be an enhancement for TC)?

Hi Jack,

it's on our wish list to be reviewed for the next releases but I cannot tell for sure it will be done and when..
