[TYPO3-templavoila] some content elements not visible in page module

[Guido tum Suden]

Hi,

In the TV page module the content elements of some pages is not visible.
The page header is, so I can edit it.
The content elements are visible in the list view and also in the list 
view within the page module.
These pages seem to have one thing in common though.
When I call up the info of a page they have in the "references from 
this items" table a line like this:
Field: tx_templavoila_to; Sorting: 0; Reftable: tx_templavoila_tmplobj; 
Refid: xx

Can anybody help?

Guido
