Hi Stoyo I'm Franco again,
I programmatically created a box, but when I try to manually add a link to it ( i.e. with the mouse)
I see the mouse pointer with an hand and the "access denied" picture.
The object is created with both AllowIncomingArrows and AllowOutgoingArrows set to True.
The access denied appears either when the icon is the OriginBox or the DestinationBox of the arrow.
In the Flowchart there are other (programmatically created) boxes already connected between them.
These other boxes can be manually connected between them.
What I've done wrong yet?

p.s. the flowChart.behavior is set to bhCreateArrow

well,  I miss to assign the AnchorPattern!

Now I only have to define my Own Achors pattern...

I hope it is possible to define all-in all-out pattern .... isn't it?

Hi Stoyo, I found the real reason why I wasn't able to create the arrows.....
the other Icons (those "programmatically created") has been created before I fire
FlowChart.FitDocToObjects(...);
The new Icons I was trying to connect was simply added outside this area without re-fitting....
so all objects outside the Fit Area cannot be connect, even if they are not locked, nor they have anchors nor AllowUnanchoredArrows  nor.....
anyway now I Fire fitDocToObjects as soon as I create any objects in the doc.
