I get an AV when I dock a Form, wich contains a TChart, into another Form. The error does not occure when the AutoPaint property of the TChart is set to True.

I have tested this with C++Builder XE6, XE7 and Delphi Builder XE6 with the standard version of TeeChart.

Steps to reproduce:

  • Create a new application with two Forms (Form1 and Form2). Both Forms should be shown.
  • In the constructor of Form1 set DockSite = true

  • Paste the following code in the constructor of Form2:

    DragMode = dmAutomatic;
DragKind = dkDock;
TChart* Chart1 = new TChart(this); //don't forget to delete
Chart1->Parent = this;
Chart1->AutoRepaint = false;

  • Start the application and dock Form2 to Form1 by dragging it with the mouse.

Can anybody reproduce this or has an idea whats going wrong?

    I can reproduce it. The exception is happening in `VCLTee.TeCanvas.pas`, which of course is not included in the standard version of TeeChart. Unless someone with TeeChart Pro installed can debug it for you, you'll need to file a bug report with Embarcadero. Have you checked the TeeChart user forums at to see if this has already been reported there? (Not setting `AutoRepaint := False` makes the problem go away, as you say.) – Ken White May 29 '15 at 14:27

    In Delphi 2010 work fine. – Val Marinov May 29 '15 at 14:35

    Spent a couple of hours installing latest pro version and could reproduce this in XE8 as well. Unfortunately the debug with source is hopelessly broken with unit name clashes all over. – LU RD May 30 '15 at 06:55

    I have posted this issue at the new QC: https://quality.embarcadero.com/i#browse/RSP-11239 – Kerem Jun 01 '15 at 06:44
  • I'm not sure about how do you exactly dock Form2 to Form1; nor what do you set at designtime and what at runtime. Could you please arrange an [sscce](http://sscce.org/)? – Yeray Jun 01 '15 at 14:58
  • I tried to simplify the steps to reproduce. – Kerem Jun 02 '15 at 11:50
  • @Yeray, the AV happens when form2 is dropped on top of form1. – LU RD Jun 02 '15 at 12:04
  • @DavidBerneda discussed with Kerem at Emb Quality Central. I guess this is answered. – Yeray Jun 02 '15 at 15:21
  • Question ist answered for now. Thank you! – Kerem Jun 03 '15 at 09:16
