[Autocomplete] 500 when using multiple=true on a not required field

[simondaigre]

Since #494, Autocomplete fields doesnt work for not required inputs.
The error : SELECT o FROM App\Entity\City o WHERE o.id IN ()

@norkunas would you take a look at this issue ?

[norkunas]

I'll try. In which case it queries without a criteria?

[simondaigre]

Sorry my GH issue description was wrong. The issue happens when :

• the autocomplete field is not required
• nothing was selected in the autocomplete field
• the whole form is submitted

[norkunas]

I've opened a PR, maybe it will fix your case?

[simondaigre]

Yes it does, thank you !
