ERROR WITH CHECKOLUMN

[near]

Hi,
I have a problem, with the "xtype": 'checkcolumn'. I can set a column in my grid, whose data index type is a boolean without problem, but when I try to set the column type to 'checkcolumn' I get this error:

Uncaught TypeError: Cannot call method 'substring' of undefined,


Can anybody tell m what's wrong, is it a bug ?

Thank's in avance

Regards

What I am using is this:

{ header: 'Column header', dataIndex: 'booleanTypeFieldInStore', width: 135,  
  renderer: function(value) {    // This function converts true and false into checkbox checked or  unchecked
    if(value == "0" || value == "false")
      value = false;
    else if(value == "1" || value == "true")
      value = true;                    
    return "<input type='checkbox' disabled='disabled'" + (value ? "checked='checked'" : "") + ">";
  }
}

It renders an HTML checkbox in the grid cell.

CheckColumn isn't a part of the core library, it's a UX. That error means that you've forgotten to include the relevant JS file.

Hi Skirtle,
does the ext-all-debug.js include UX files ?

[Farish]

No. You may include it by putting it in Ext.require:

Ext.require([
    // any other things you use
    'Ext.ux.CheckColumn'
]);

[skirtle]

Using Ext.require will only help if you have the dynamic loader enabled and the UX files are in the right place.

You'd be better off just including it using a script tag. CheckColumn.js can be found in the ExtJS zip file you downloaded. It's in the directory examples/ux. It also needs a CSS file, CheckHeader.css, and the 2 images mentioned therein.
