I found that when the program creates a form from scratch everything works but when I try to go back to reshow the form (after I have been to another form) then it gets the AV, etc.

For now I had to roll back to iw15.1.22

Here is some more information that might help.

I am running this code

function fxGetForm(aWebApplication: TIWApplication; aFormName: string): TIWAppForm;
var
  lthisPage: TIWAppForm;
  lthisPageClass: TIWAppFormClass;
begin

  lthisPage := TIWAppForm(aWebApplication.FindComponent(aFormName));
  if lthisPage = nil then
  begin
    lthisPageClass := TIWAppFormClass(FindClass('T' + aFormName));
    Result        := lthisPageClass.Create(aWebApplication);
  end
  else
    Result := lthisPage;
end;


with TfrmClaim(fxGetForm(WebApplication, 'frmClaim')) do  -> frmClaim represents some page to move to
        begin
          BeforeShow;
          Show;  ->  this is where the error occurs,  but the error only occurs if the "lthisPage" in the fxGetForm function is nil and thus forces the creation of a new page.
        end;

We have already identified one situation where an AV can happen when using CG Dev Tools controls. We have already fixed it in our codebase and we are about to release an update which should fix it.
