Dynamically create and remove components on unitabsheet

[d.bernaert]

Hi,

I'm trying to create dynamically controls on a unitabsheet and recreate them in function of a selection of the user.

I see some weird behaviour when trying to remove components, components that are on another tabsheet become visible on the tabsheet where i remove the components.

I'm using this routine to remove the components:

 

I := Unitabsheet.ControlCount - 1;

While I >= 0
do begin
          WorkControl := Unitabsheet.Controls[I];
           if assigned(WorkControl)
           then FreeAndNil(WorkControl);
           Inc(I, -1);
      end;

Hmm, how can we reproduce this issue?

I will try to create a testcase

Think i found it.

I was trying to remove components when the form was not yet in the ready state.

Still having problems.

Here included is a very simple test case.
