Thanks,

I have this problem since several months !

Here is the complete method :

void psMainWindow::on_Menu_Save()
{
	if (_currentFilePath.length() < 1)
	{
		on_Menu_SaveAs();
		return;
	}
 
	UpdatePanelWidget::Start();
 
	pureGraph::IE::Exporter exporter;
	string file = _currentFilePath.toStdString();
	exporter.Export(GlobalContext::Scene, file);
 
	UpdatePanelWidget::Stop();
}

void psMainWindow::on_Menu_Save()
{
	if (_currentFilePath.length() < 1)
	{
		on_Menu_SaveAs();
		return;
	}

	UpdatePanelWidget::Start();

	pureGraph::IE::Exporter exporter;
	string file = _currentFilePath.toStdString();
	exporter.Export(GlobalContext::Scene, file);

	UpdatePanelWidget::Stop();
}

To copy to clipboard, switch view to plain text mode

and you say that when you stand on line 13 in the debugger, '_currentFilePath' has a valid string in it, and 'file' is an empty string?
