CXTPObservable leaks during XTPShutdown

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi, I am currently migrating from CodeJock 19.3 to CodeJock 24.0 and found that this issue is occurring to me. I use the static function CXTPPaintManager::SetTheme(xtpThemeVisualStudio2015) to set the theme for the paint manager. 
However, when I call CXTPWinApp::ExitInstance(), and as the app starts to close, when XTPShutdown() is called during ~XTPApplication(), I get an assertion error during:
template<class Owner, class Observer>
AFX_INLINE CXTPObservable<Owner, Observer>::~CXTPObservable()
{
    ASSERT("All observers must be unsubscribed before destruction" && 0 == m_Observers.GetSize());
}

I can use CXTPPaintManager::SetTheme(xtpThemeOffice2000) before calling CXTPWinApp::ExitInstance(), this error doesn't occur. I wanted to ask if there is a more elegant solution, or if this workaround is the only solution at the moment.

	Hello, It seems that quite a bit of time has passed between these revisions. We have modified application themes, now it uses XTPPaintManager()->SetTheme(nTheme); call instead of CXTPPaintManager::SetTheme(), maybe this is the problem. Please see how this is implemented in CommandBarControls. Regards, Artem Gonarenko
