(Note, I'm assuming this is Ext 3.x as you're using JsonStore.)

Double-check that your store is valid: add a load handler, and using Firebug, put a BP in it, and examine the contents of "store".

Use Firefox + Firebug and take a look at what is being returned by usersdata.js in the console.

Take a look at Ext.data.Model and the data package.

Folks,

It's only a minor thing, but after you download Ext JS 4.0.2a, the "Thank You" page points you to the legacy "Learning Center" page...

[by fay]

Have you looked at the tutorials, e.g., HTML Page Setup?

Use ext-all-debug.js to get a better idea of where the error is occuring.

[by fay]

'AM.model.User' - as that's the name you've given your model.

[by fay]

The problem is that you just mixed up the examples... There would be no reason for the Ext.data.Model example to reflect the stuff that's in the MVC guide.

[by fay]

Would you not just read the model config?

Have you double-checked that your JSON is valid with www.jsonlint.com? With IE it tends to be a trailing comma issue, other browsers are more tolerant of that.

See the toggle() method.

Note, that I put in (cell[1], cell[0]) - row and col are swapped

[by fay]

Would you happen to have disableCaching set to false?

I think this is what you're referring to (in section III): http://docs.sencha.com/ext-js/4-0/#/guide/class_system

Take the \examples\grid\edit-grid.js example and change the load callback to:



store.load({
callback: function(){
grid.startEditing(0,1);
}
});

From the docs for getSelectedCell:



... so try:



var cell = this.grid.getSelectionModel().getSelectedCell();
this.grid.getColumnModel().getCellEditor(cell[1],...

Assuming 'TabPanel' is the id you've assigned your Ext.TabPanel:



var title = Ext.getCmp('TabPanel').getActiveTab().title;
// Note: Make sure you use the setTitle() method if you want to...

[by fay]

Take the \examples\grid\array-grid.js example and add itemmouseenter and itemmouseleave listeners:



var grid = Ext.create('Ext.grid.Panel', {
// ...
listeners: {
itemmouseenter:...

[by fay]

Why do you need the hidden "id_hopital" column when you have this data available through the store?

[by fay]

RE: loading box. See Ext.grid.View's loadMask config.

EDIT: Btw, this was answered earlier - see:...

[by fay]

Also take a look at the Ext.grid.View getRowClass method.

Take a look at Ext.History.
