try     value="#{true}"  first, if it checked, error in your selected property

Does it do this even if you omit the binding attribute?  I'm just guessing, but maybe that's interfering with it.

I understand the part about the event handling for selectAll.

But I'm worried about having the checkbox checked.  There must be some reason why the checkboxes for the rows as specified in the below code does not actually render as checked. I'm just breaking my head over that reason. I assumed, when u specify the value "true", it gets displayed as checked.

 

Thanks

Also, if you wanted to avoid the _javascript_, you could implement selectAll as an action method.  The easiest way is to remove the immediate="true" attribute and the event handler, and have your action bean just spin through the elements of your data bean, setting each one to true and returning "success" (or some other outcome) that causes the page to be redisplayed.  (If you do it this way, you may have to do a <t:saveState> on your bean to make sure your list remains in the component tree.)

The "binding" attribute is for associating a reference to your component to a backing bean.
I think you want to be using value="#{DataTableHandler.selected}" instead.

Also, since your header checkbox is really just a client-side _javascript_ executor, it might be better to implement it as raw html (wrapped by f:verbatim).

Hi,

My code looks like this.

            <h:column id ="checkboxColumn">
                <f:facet name ="header">
                    <h:selectBooleanCheckbox id="headerCheckbox"
                        binding= "#{DataTableHandler.headerSelected}"
                        immediate= "true" onclick="selectAllRows()" />
                </f:facet >
                <h:selectBooleanCheckbox id="rowCheckbox"
                       binding= "#{DataTableHandler. selected}"
                    value= "true" />
            </h:column >

When I execute this, the header checkbox is selected, where as the other checkboxes in the rows are unchecked. Can anyone help me understand why that happens?

Thanks
Balaji
