Checking the first radio box in a dataTable on initial load

Question

Hi,
I have a datatable bound to a UIData object in a backing bean. The data table has a radio check box widget which I use to select a data row. I would like to have the first checkbox checked on an initial load, I tried using EL to no avail.....
Any suggestions or syntax advice is appreciated. Here is my JSF tag inside the data table.... note, friends is a reference to a session variable containing the UIData elements.
<h-bud:column id="budSelected">
                        <f-bud:facet name="header">
                            <f-bud:verbatim>�</f-bud:verbatim>
                        </f-bud:facet>
                        <h-bud:selectOneRadio id="budSelectedValue" value="#{ (friends.data.rowIndex eq 0) ? 1 : 0 }" valueChangeListener="#{friends.doOnSelectRadio}" onclick="selectOne(this.document, this);" immediate="true"><f-bud:selectItem itemValue="#{friendsList.friend.id}" /></h-bud:selectOneRadio>
                        <f-bud:facet name="footer">
                            <h-bud:column id="budEmpty">
                                <f-bud:verbatim>�</f-bud:verbatim>
                            </h-bud:column>
                        </f-bud:facet>
                    </h-bud:column>Cheers

Hi Meghasyam
Thanks for the reply, I am setting the value of <f-bud:selectItem itemValue="#{friendsList.friend.id}" /> to the value of my "Friends" primary key ID, so I know which user was selected when the form is submitted?
If im correct in understanding you, you are saying that this value must alway be 1. If this is the case, where can I tag a value to the radio box associating it with an ID?
I need to use a radio button UI widget as a checkbox is associated with multiple selections which is not allowed on my form, I need to only allow one selection of the table row per display.
