How do I properly form my tpl for the BreadCrumb snippet in MODx Revolution?

Question

I am transitioning from the Breadcrumbs snippet to the BreadCrumb snippet.

This is my Breadcrumbs code:

[[Breadcrumbs? &respectHidemenu=`0` &crumbSeparator=`` currentAsLink=`false` &showHomeCrumb=`0` &titleField=`bc-title`]]

This is my BreadCrumb code:

[[BreadCrumb? showHidden=`0` showBreadCrumbAtHome=`0`]]

I am trying to mimic the titleField portion from Breadcrumbs in my BreadCrumbLinkCrumbTpl and my BreadCrumbCurrentCrumbTpl using (so if bc-title is empty, rollback to pagetitle):

<li><a href="[[+link]]">[[*bc-title:empty=`[[+pagetitle]]`]]</a></li>

It works great on BreadCrumbCurrentCrumbTpl, but on BreadCrumbLinkCrumbTpl it is only showing pagetitle, not bc-title first. It's almost like it can't traverse? Thoughts?

As far as I know, Breadbrumbs does not have any settings for including template-variables (which sucks). You could do a simple workaround like this:

<li><a href="[[+link]]">[[!parseNavTitle? &sid=`[[+id]]`]]</a></li>

The snippet parseNavTitle:

$obj = $modx->getObject('modResource',$sid);
if ($obj->getTVValue('bc-title') == '')
    return $obj->get('pagetitle');
else
    return $obj->getTVValue('bc-title');
