maybe using pageBeginRender for init is a viable solution:
.... extends BasePage implements PageBeginRenderListener{
...
public void pageBeginRender(PageEvent event) {
if(getFirstObject() == null)
setFirstObject(new Object());
}
..

That is one way to do it, however make sure you use the right attributes.
<span jwcid="@If" condition="ognl:firstObject">
<!-- your stuff goes here -->
</span>
