    Are you calling the function before or after render? The element is only available after render.

    Ext.define('LNM.view.newAccount.NewAccountForm' ,{
    extend: 'Ext.form.Panel',
    alias : 'widget.NewAccountForm',
    title:'Create New Account',
    frame: true,
    bodyStyle: 'padding:15 15 15 15',
    autoScroll: true,
    height:400,

    items: [{
    xtype: 'fieldset',
    title: 'Estate Information',
    collapsible: true,
    layout: 'anchor',
    anchor: '100%',
    items:[{
    xtype: 'textfield',
    anchor:'30%',
    labelWidth: 100,
    fieldLabel: 'Estate Location',
    name:'estateLocation',
    flex: 1
    },{
    xtype: 'textfield',
    anchor:'30%',
    labelWidth: 100,
    fieldLabel: 'Estate Officer',
    name:'estateOfficer',
    flex: 1
    },{
    xtype: 'textfield',
    anchor:'30%',
    labelWidth: 100,
    fieldLabel: 'Estate Assistant',
    name:'estateAssistant',
    flex: 1
    },{
    xtype: 'textfield',
    anchor:'30%',
    labelWidth: 100,
    fieldLabel: 'Estate Comments',
    name:'estateComments',

    }]
    },{
    buttonAlign: 'center',
    buttons: [{
    text: 'Reset',
    handler: function() {
    this.up('form').getForm().reset();
    }
    }, {
    text: 'Submit',
    formBind : true,
    id:'newaccountSubmitButton'
    }]
    }], // End of CallTrackForm items




    initComponent: function() {
    this.callParent(arguments);
    }
    });

    This is my panel.

    var accountPanel = Ext.widget('NewAccountForm');
    accountPanel.getEl().dom.innerHtml; // This line is in the handler of a button and it throws the error getEl is undefined.
    accountPanel.getEl().dom.innerHTML;

    Please use code tags, the code above is (almost) impossible to use.

    I think the issue is that you are instantiating the component (using Ext.widget()), but that doesn't mean it gets rendered. I think that when you do this it will work:

    Code:
    var accountPanel = Ext.widget('NewAccountForm', {
      renderTo: Ext.getBody()
    });
    accountPanel.getEl().dom.innerHtml; // This line is in the handler of a button and it throws the error getEl is undefined.

    Yes I have put that in my example as well

    Code:
      renderTo: Ext.getBody(),
    but you can also render it on a div or add the field set to a formpanel.
