toStdString is returning an empty string !!!!

[pl01]

Hi,

Often, but not each time, "toStdString" is converting the string into an empty string !! It is completely random and do not know how to solve this problem ?

do you have any idea ?

Thanks

Did you make sure the input string is not empty in the first place? if so how?
Post your code.

Yes, I'm in the debugger and the debugger show me the content of my string... everything sounds fine !!!
Here is the code... so simple !!!

string file = _currentFilePath.toStdString();

can you show the following several lines too?

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();
}

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?
