connectSlotsByName and clicked()

[xkazielx]

I'm having problem that is driving me nuts. I'm also using setupUi with on_objectName_signalName() connections. When I call:

void on_DateButton_clicked()
{
       this->setWindowTitle("Some title");
}

void on_DateButton_clicked()
{
       this->setWindowTitle("Some title");
}

To copy to clipboard, switch view to plain text mode 

this works fine but:

void on_DateButton_clicked()
{
       lineEdit_2->insert("Some text");
}

void on_DateButton_clicked()
{
       lineEdit_2->insert("Some text");
}

To copy to clipboard, switch view to plain text mode 

app crushes.
Any ideas?
I appologize for my poor English.

are you sure that "lineEdit_2" is class member? are you sure that "lineEdit_2" contains not null pointer? maybe you should use "ui->lineEdit_2" instead.
