TYPO3 Core

Yes. Seen that. This is probably "only" a display issue, but unfortunately not that easy to resolve.

This is caused by a trimExplode in TcaSelectValues that keeps empty entries. If that is removed (TRUE added iirc), then other select stuff behaves weird, instead. Reason is here that sometimes an empty value is ok (for static value lists) and sometimes it is not ok (for relations).

Problem is here that the two data provider TcaSelectItems and Values should probably be one provider, where the "static" list of valid values (entries coming from static item list, or are added via pageTs and friends) is determined and nailed, and after that the dynamic entries are determined.

• fetch items from static list (the first group of methods in TcaSelectItems)
• validate / determine values that fall are added by that
• fetch items from dynamic sources (foreign_table & friends)
• validate / determine values that are added by this category that did not fall into this the first area that.

At least that was my idea when i stumbled upon this issue. There is also a @todo in TcaSelectValues that says something similar. I think the former DataProprocessor code handled selectValues in a similar way as outlined above, but probably I unfortunately ignored this fact and now we have this issue ...

Also, this is what i think was required to fix this issue, but i'm also not 100% sure if that is the right track ... at least separating the 'static' value determination within databaseRow field from the 'dynamic' part should at least help to nail this issue a bit better.
