Javascript/ExtJS - get Codemirror Editor by textarea

Question

Hello stackoverflow community,

i just built a Codemirror Editor into an ExtJSProject like so:

addCodeMirrorPanel: function() {
   this.getAixmFormarea().add(Ext.widget({
        xtype: 'textarea',
        fieldLabel: 'AIXM',
        autoScroll: true,
        name: 'aixm',
        id: 'codearea',
        width: 800,
        height: 300,
        resizable: true,
        resizeHandles: 's se e',
        listeners: {
            afterrender: function () {
                var textarea = Ext.getCmp('codearea');
                var codemirror = CodeMirror.fromTextArea(textarea.inputEl.dom,{
                    lineNumbers: true,
                    content: '',
                    matchBrackets: true,
                    electricChars:true,
                    autoClearEmptyLines: true,
                    extraKeys: {"Enter": "newlineAndIndentContinueComment"}
                });
            }

        }
    }));

}

Now what i want to do is access the codemirror editor from a different Controller function and im not quite sure about how to do that. no getinstance() , geteditorbyID() or similar methods are specified in the codemirror manual and i cant seem to access it from the now hidden textfield either.

Well why are you discarding the instance after you are creating it? Perhaps you could simply store it on the widget?

this.codeMirror = CodeMirror.fromTextArea(...);
