Signals being triggered twice on a dialog window

Message 1 in thread

Hi all,

I have an application with a main window, that calls a dialog window. On the
dialog constructor I have some connect() oeprations and stuff.
The problem is that every signal is triggered twice... If I press a button,
the application executes its method twice.

For example, I have this on the dialog constructor:
    connect(configDialog.btnSelectColor, SIGNAL(clicked()), this,
SLOT(on_btnSelectColor_clicked()));

And this is the slot method:
void JSSConfigurator::on_btnSelectColor_clicked(void)
{
    // QMessageBox::critical(this, "Test", QString("Triggered!"));
    QColor newcolor = QColorDialog::getColor(cellColor, this);

    if(newcolor.isValid())
    {
        cellColor = newcolor;
        colorPalette.setColor(QPalette::Background, cellColor);
        configDialog.frColor->repaint();
    }
}

Every time i click on the button the ColorDialog appears twice... It is the
same for every signal/slot I have on this dialog.
I tried using other signals like released() but got no luck.

Any ideas??

Thanks a lot!!

I guess you're making a call to setupUi() also... your slot naming 
scheme conforms to the Trolltech auto connection scheme:

Hi Tim,

Didn't know about that one!!! I'll try to comment out the connections I made
and see if it solves the problem!!

Thanks a lot!
