    post some code... guessing, you "think" a variable has an object but it is not there... use console.log of that variable before calling parentNode and you will see it is empty

    Hi when I am trying to use below code, I am getting the error.
    Code:
    updateRec = Ext.getCmp('formpanel').getForm().getRecord();
    if(updateRec) {
     		Ext.getCmp('formpanel').getForm().updateRecord(updateRec);
    }
    I am declaring updateRec as variable at the top of file.

    Please always post the full stacktrace with an error.

    My guess would be that the record is backing some sort of view and it's the view that's struggling.

    the "chain" of methods make dificult to debug. try to split your code and console.log each "get" to see where it fails
