View Full Version : this.store.un is not a function with my_window.close()

14 Jan 2011, 2:32 PM
Hey guys,

I have a "publish" button on my grid that produces a Ext.Window that contains a formPanel and some buttons.

After the user does anything, I want that window destroyed with the .close() method. Problem is when the call this.close(), I get the following error:

this.store.un is not a function
this.store.un('beforeload', this.onBeforeLoad, this);
ext-all-debug.js (line 38968)

Any clues???

A little more background, I am passing a reference to the grid to the window, so it can call some grid methods for data:

if (!email_win){
var email_win = new pub_email.emailwin({ grid: this });

It doesn't matter if I call this.close() from within the emailwin object, or if I call email_win.close(), I get the same error.
I did try setting this.grid = undef before calling close, thinking that may be the issue, but that didn't work.

I'm pretty certain that re-declaring var email_win within your check is wrong:

if (!email_win){
var email_win = new pub_email.emailwin({ grid: this }); // Remove the var

email_win should be defined *somewhere* (accessible) before the if statement.

Without seeing more of your code, it's hard to say what is causing the "un" error.

Yeah, I've played around with that. Actually, all the exit path's from email_win should call .close(), so email_win will always be destroyed on exit and re-created when publish is clicked.

This code behaves with the same error message:

var email_win = new pub_email.emailwin({ grid: this });

There are thousands of lines of code in this application, and I really clueless what I should post.

This is the final exit method of the email_win:

handlePublishEmail: function(btn, obj){

var comments = "";
var to = "";
var subject = "";

var emailFormPanel = Ext.getCmp('emailPrepForm');

var f = emailFormPanel.getForm();
var form_data = f.getFieldValues();

if (btn.id == 'cancel'){

if (btn.id == 'sendWithComments'){
to = form_data.to;
subject = form_data.subject;
comments = form_data.comments;

pub_email.AJAXPublishSelectedToDB(this.grid, comments, to, subject);

var selected = this.grid.getSelectionModel().getSelections().length;
var msg = "Sent email regarding "+ selected +" runs";

have you tried to play with the autoDestroy:true|false properties on your window and/or grid ?

Hmmm, good idea. Just finished playing with the autoDestroy settings -- no change in behavior. There doesn't seem to be an autoDestroy property to gridPanel BTW.

I also just noticed the "removeAll()" method to both these objects -- again no change. Still getting that error. I wish I had a clue what was happening here.

gridPanel have no autoDestroy ?... thanks ! :-)))
so if the grid don't have it... then... go deeper... try to see on your store ! same stuff ! you must find somewhere :-)

or... it seems like your window, try to destroy the store and not find her... so, or put store autoDestroy:false, for letting the window to do this , or, try to f..orward it and, before close occurs on window...
Like this :

yourwindow.on('beforeclose', function() {
yourwindow.yourstore= null;

That error is from destroying a combobox on the window. How exactly was that combobox configured?
