An AV when dynamically recreating columns with Properties assigned from an edit repository item if a tree list's OptionsView.CellAutoHeight property is set to True

created 12 years ago

Hi,

An access violation occurs when changing the configuration of the tree component. I was able to create a small test application where the issue is recreated - although it happens there only when the application is built using FastMM with FullDebugMode directive. The error occurs in the production application also when FullDebugMode is not used. The test application project is attached to this message.

The error occurs with the following steps in the test application:

  1. Press "Button1"
  2. Press "Button2"
  3. Press "Button3"
  4. Press "Button4"
    -> Access Violation (or if build with FullDebugMode directive, an attempt to call a virtual methd os a freed object)

The error was recreated with DevEx 2011 vol 2.9 and 2012 vol 2.6.

    Hi Tom,
    I have launched your test application and found that the main form contains only two buttons (Button1 and Button2). I have clicked them several times, but an AV didn't occur. Perhaps I'm missing something.
    Would you please check to see whether or not your attached project is the correct one? If so, please provide us with exact steps to reproduce the issue.
    I am looking forward to hearing from you.

      Hi,
      As I mentioned in the message, the error occurs in the test application only if it is built using FastMM memory manager and using the FastMM's FullDebugMode compiler directive. The error occurs in our production application also without the FullDebugMode directive.
