View Full Version : Reset a re-used FormPanel

16 Jul 2011, 3:49 PM

i understand that the reset() method of the FormPanel resets all fields to their INITIAL values. this does not work as expected if a form gets re-used.

here's the scenario:
- create a new form
- load model A into the form
- load model B into the form
- reset the form -> form gets reverted to the values of model A

is there a way to reset the form to the values of the last loaded model?

why not destroy the form panel after use and then recreate it. this would reduce memory footprint also.

i thought about this possibility too, but decided against it because this form is a base component of my app and is used very frequently, so a new instance had to be created all the time.

i implemented now my own reset() functionality.

var currentEditorModelClone;
function createModelClone(){
var editor = myapp.views.MyEditor;
var rec = editor.getRecord();
currentEditorModelClone = rec.copy();

function revertModel(model){
for(prop in currentEditorModelClone.data){
model.data[prop] = currentEditorModelClone.data[prop];
