[SalesForce] lightning:datatable link to sObject

Don't have the reputation points for a comment but the only way I've figured out how to do this is by using HTML5 session storage. You can add the equivalent of the query string to the session storage, then fire the navToURL event and then on the navigation destination side read from the session storage, get the params, and clear them. It's a hack but the only thing i've figured out so far.

When using the LDS styles, always the specify id for the input tag and for attribute for its corresponding label tag which should be same and must be unique for an input tag.

Add an attribute id to be passed along with other values to the component:

<span class="slds-button slds-radio--button">
    <input id="{!v.id}" name="{!v.name}" type="radio" value="{!v.value}" checked="{!v.checked}" onclick="{!c.handleClick}"/>
    <label class="slds-radio--button__label" for="{!v.id}">
        <span class="slds-radio--faux">{!v.label}</span>
    </label>
</span>

NOTE: {!v.id} shoud be unique for the radio buttion
