    Default Answered: Combobox does not show selected value

    Answered: Combobox does not show selected value


    I have a first combobox with a change event listener.
    When the user selects a value in this first combobox, its change listener creates a second combobox (propiedad) and assigns it the following store:

    Code:
    propiedad.store=Ext.create('Ext.data.Store', {                                   
       fields: ['valor'],                                    
       data : [{'valor':'HOME'},{'valor':'WORK'}]
    });
    propiedad.displayField= 'valor';        
    propiedad.valueField= 'valor';
    propiedad.setEditable(false);
    The second combobox, when dropped-down, shows the options HOME and WORK properly, but when I click on either of these options, the combobox drops-up but remains empty, although I know that the value has been assigned through a alert(propiedad.value) in the change listener of this second combobox.

    ¿Why the combobox does not show the selected value?

  2. You shouldn't change the valueField or displayField after instantiation.
