Parent record is not shown after saving the first time to a table on a TYPO3 system
Imagine you have two tables tx_myext_parent and tx_myext_child and these tables are "fresh" or were truncated before.
If you create your first parent record with some children and save the parent record (not save&close), the correctly created parent record will not be shown.
The reason is in alt_doc.php. A check should prevent from showing newly created child records because the parent was initially edited. The new child records are memorized in TCEmain's array "newRelatedIDs".
