Hi. I was wondering if this is the correct behavior. im using ff 3.6 and if i inspect the disabled button with firebug, ith has no disabled property, it only has the following.

<button id="btnEliminar" type="button" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only ui-button-disabled ui-state-disabled ui-state-focus" role="button" aria-disabled="true"><span class="ui-button-text">Eliminar</span></button>

However, Im able to click it and it responds to click event. I can say that the styling is alright.
