Here's your reason, basically the theming changes in D7 mean the field theming gets bound a lot lot later in the process, so it's not possible to generate the output into a Textarea for you to edit - that said, it is possible that we can come at this from another angle and use tokens instead BUT it means what you see in contemplate admin page will be nothing at all similar to the output.
The Content Template (a.k.a. ConTemplate) module allows modification of Drupal's teaser and body fields using administrator defined templates. These templates use PHP code and all of the node object variables are available for use in the template. An example node object is displayed and it is as simple as clicking on its properties to add them to the current template.
The taxonomy_breadcrumb module generates taxonomy based breadcrumbs on node pages and taxonomy/term pages. This module fixes the common complaint of having "Home" be the only breadcrumb on node pages. The breadcrumb trail takes on the form:
[HOME] >> [VOCABULARY] >> TERM >> [TERM] ...
Simply install the module and taxonomy based breadcrumbs will appear on node pages and taxonomy/term pages. For the most common applications this module will work "out of the box" and no further configuration is necessary. If customization is desired settings can be changed on an administration page.
The Frequently Asked Questions (faq) module allows users, with appropriate permissions, to create question and answer pairs which they want displayed on the 'faq' page. The 'faq' page is automatically generated from the FAQ nodes configured. Basic Views layouts are also provided and can be customised via the Views UI (rather than via the module settings page).
Adds the ability for users to add tags (taxonomy) to themselves on their user/edit page. Tags are also displayed on the user/page and they link to a page that lists all users that have that tag set to them.
