I added a “change font color” button to a CXTPToolBar. The code is as follows:

int PEBookmarkCtrl::OnCreateControl(LPCREATECONTROLSTRUCT lpCreateControl){    switch(lpCreateControl->nID)    {    case ID_BKCTRL_COLOR:        CXTPControlPopupColor* pPopupColor = new CXTPControlPopupColor();        CXTPPopupBar* pColorBar = (CXTPPopupBar*)CXTPPopupToolBar::CreateObject();        pColorBar->GetControls()->Add(new CXTPControlButtonColor(), ID_BKCTRL_COLOR_NONE);        pColorBar->GetControls()->Add(new CXTPControlColorSelector(), ID_BKCTRL_COLORSELECTOR);        pColorBar->GetControls()->Add(new CXTPControlButtonColor(), ID_BKCTRL_COLOR_MORE);        pPopupColor->SetCommandBar(pColorBar);        pColorBar->EnableCustomization(FALSE);        pColorBar->InternalRelease();        lpCreateControl->pControl = pPopupColor;        return TRUE;    }    return FALSE;}

After changing the icon to an SVG, an assertion started occurring.
It happens when CXTPControlPopupColor::SetColor() is called in the ON_UPDATE_COMMAND_UI handler (see attached).
What should I do to fix this?
