Story #69712: Further FormEngine development
group maxitems woes
100%
Description
The maxitems setting for TCA group fields is somehow unclear.
tca docu states there is a default of 1 if no maxitems is set. but this only seems to fire in case there is no mm relation (?).
for "csv" relations, the maxitems=1 is active. Current behavior is that if no maxitems is set in csv relation and default 1 kicks in, the formengine still allows selecting more than one element, but datahandler throws all of them away except the first one on saving. this is a bug in formengine validation and should be fixed.
Additionally, we should find out when, where and why the maxitem default kicks in and think about if that makes sense, or if a different default should be chosen consistently (0 for "no restriction, or 9999 or similar?). This implies thought about b/w compatibility and maybe a tca migration, then.
it might be a good idea to enrich ext:styleguide with additional scenarios to nail the current and the expected situation.
