Dojo dGrid header checkbox to select all does not

I created a dojo dgrid however i used a form wizard to seprate the fields on the form, however with the current structure i am having an issue with the select all feature on the grid.

I cannot select all however if i remove the div Page2 and it content from the form it works.

In firebug i also inspected the DOM and i saw the 'aria-checked = mixed' when i check the select all box when it should be 'aria-checked = true'.

How can i get the header checkbox to allow all records to be selected when it is checked and the grid is in a Wizard form.

Under is some screen shots and code:

jsp

 <div data-dojo-type="dojox.widget.Wizard" hideDisabled="true"
            data-dojo-props="style:'height:300px; width:600px'">        



    <div dojoType="dojox.widget.WizardPane" id="Page2">

                    id="EmployeeBirthNameContainer">
                    <label>2. Is you name on your Birth Certificate is 
                        different from (1) above ?(e.g. Changed by Deed Poll / Marriage)</label>

You should not be mixing selector and editor into your constructor - they are not designed to be used that way. They are designed to wrap column definition objects (which you are already doing for selector column, though I'd note that selectorType: "checkbox" is unnecessary since that's already the default).

Also, unrelated, selectionMode starts with a lowercase s.

Not sure if this will solve your problem but it will definitely prevent some weird behaviors in general.
