if you run the same example, it will show the combo box with 3 items.
select anyone item and then try to change your selection by again clicking on the same combo box, this time it will have only one item listed which is your previous selection

conn.request({
url: ‘movie-update.php’,
params: {
action: ‘delete’,
id: e.record.id
},

Error : e.record.id is undefined.

Replace it by sel.data.id and it will work !

e.commit() is not a function
e.reject() is not a function

Both should refer to e.record.commit() and e.record.reject()

Ext.form.VTypes['nameVal'] = /^[A-Z][A-Za-z\-]+ [A-Z][A-Za-z\-]+$/;

Notice the space in the regex after the ‘]+’.

Page 50: This was a requirement with version 2.1, but a later release fixed the need to initialize tooltips to use the htmleditor.

Thanks for finding these things.

Text reads:

“This is the first Ext component we have used that requires the QuickTips component to be initialized before we can use it.”

However, I tried commenting out Ext.QuickTips.init(); and it still worked, albeit without the descriptive tooltips.

So, perhaps, it should say that the descriptive tooltips for the buttons (bold, italics, etc.) won’t appear if QuickTips is not initialized. Or the sentence could just be removed.

Code in book reads:

Ext.form.VTypes['nameVal'] = /^[A-Z][A-Za-z\-]+[A-Z][A-Za-z\-]+$/;
Ext.form.VTypes['nameMask'] = /[A-Za-z\- ]/;
Ext.form.VTypes['nameText'] = ‘In-valid Director Name.’;
Ext.form.VTypes['name'] = function(v){
return Ext.form.VTypes['nameVal'].test(v);
}

but it doesn’t work once I tried it.

However, I downloaded the code samples and tried using the one in “4_forms_custom_vtype_validation.php,” which is:

Ext.form.VTypes.nameVal = /^([A-Z]{1})[A-Za-z\-]+ ([A-Z]{1})[A-Za-z\-]+/;
Ext.form.VTypes.nameMask = /[A-Za-z\- ]/;
Ext.form.VTypes.nameText = ‘In-valid Director Name.’;
Ext.form.VTypes.name = function(v){
return Ext.form.VTypes.nameVal.test(v);
};

and that one worked.

The funny thing that I didn’t notice till just now is that the publisher changed the phrase from “Work Sucks” – the actual tag line for the movie – to “Dull Work” during the editing process.

However, the code shows that “Dull Work” is entered into the DIV if “the office” is entered in and the custom text is entered into the DIV if anything else is entered into the prompt.

As for page 79, that is not actually what needs to change. The introduction to modifying the column models properties is on page 86.

The code samples were tested, and the problem you ran into does not exist in the code samples download, only in the text of the book.

I would love it if I had a “team” to do these kinds of things, but im guessing the picture in your head about how books are produced is much grander than how it actually happens.

Here’s the column model that code I pasted is supposed to operate on, which is on page 79:

{header: “Title”, dataIndex: ‘title’},

So you can then pass id parameters to those column objects! Awesome! I think it would be a good idea to explain that when you correct the code sample above.

{header: “Title”, dataIndex: ‘title’, id: ‘title’},

On page 96 you use another function, still operating on the same column model which is missing the id parameters, getIndexById, which will also be broken with the incomplete column model it’s expected to be used with from the book.

I think it might be a good idea to have someone on your team actually go through and test all of the code samples and then update the PDF ASAP. Thanks.
