[Vala] Cannot convert from `Gtk.ComboBoxText.get_active_text' to `string'

[Sascha Manns <Sascha Manns mailbox org>]

Hello list,

i created a class what contains:

// Properties
public string doctype { get; set; }

// GUI Elements
[GtkChild] private Gtk.ComboBoxText cboDocType;

// on_cboDocType_changed gets the chosen document type
[GtkCallback]
private void on_cboDocType_changed () {
    doctype = cboDocType.get_active_text;
}

The compiler says:
ui/create_publication.vala:45.2-45.37: error: Assignment: Cannot convert
from `Gtk.ComboBoxText.get_active_text' to `string'
    doctype = cboDocType.get_active_text;
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

But as far as i know the combobox text is a string. So it should work.

What can i do?

Greetings
Sascha
