TYPO3 Core

If you use combo mode and remove a record that currently does not satisfy the validation, you cannot save the "page" anymore and get this error message: "The fields marked with a yellow exclamation mark are not yet correctly filled in. Please complete them properly"

As a test case you can use the IRRE Tutorial extension. Then edit a "m:n asymmetric combo" Hotel. Create a new offer and simply delete it without filling in anything. Then try to save the page. You should then get this error message. From that point on you have to reload the page (and possibly lose all changes you did so far).

On removal of the record, the relation record is set to display: none. Therefore the combined record is also hidden. But only the validation of the relation record is disabled, the one of the combined record is still active.

I did some short investigations, but it seems to be far too complex for me to figure out how to cleanly do this. As a reference here a call stack for class.t3lib_tceforms_inline.php:

renderForeignRecord
renderForeignRecordHeader
renderForeignRecordHeaderControl
... renders onclick=deleteRecord link
... which will only remove the validation of the relation record
renderCombinationTable
renderMainFields
... this is where more (combined) required fields are added

There is also some hidden input field rendered in getSingleField_typeInline with class inlineRecord. That may have to do something with this, but I'm not sure.
