[Flow] Re: Relations of created sub-properties

[Teo C.]

Hello,

I tried as suggested to add an hidden field in the fluid template, but still the "one" side (in this case "newConcert"), still comes out empty and the relation is lost in the "many" side ("artists").

Does anybody know what is the recommended way to create sub-properties in the same form of the main property ?

Thanks for any hint !

Teo
