Wt

After installing wt-3.2.3 and using it I got directly a core-dump during initialization of our Wt-App:

It seems to me that there is a currentIndex_ != --1 is missing:

void WStackedWidget::setCurrentIndex(int index, const WAnimation& animation,
                     bool autoReverse)
{
   ...
   if (isRendered() && javaScriptDefined_)
      doJavaScript("$('#" + id() + "').data('obj').setCurrent("
           + widget(currentIndex_)->jsRef() + ");");
  }
}

It should be:

 if (isRendered() && javaScriptDefined_ && currentIndex_ != -1)
      doJavaScript("$('#" + id() + "').data('obj').setCurrent("
           + widget(currentIndex_)->jsRef() + ");");
