Hi, I’m a newbie in tornadofx.
I want create a wide form with many input fields, starting with followed source code, using
tornadofx 1.7.20, Kotlin 1.6.20, sdk Oracle OpenJDK 1.8:

class test : View("Titolo")
{
    override val root = flowpane() {
        form() {
            fieldset("grup") {
                field("label") {
                    textfield ()
                }
            }
        }
    }
}

but executing it I get these errors:

why?

Exploring tornadofx source code I notice that the field() function, which allow to creating input object with their label, can be only using in conjunction with form() and fieldset(); while it would be very useful to be able to use the field() function freely!
@MicheleSaltori MicheleSaltori changed the title how to use field() | and why field() cant' be used without form() how to use field()? | and why field() cant' be used without form()? May 17, 2022
