How can I see validation decorators immediately when first opening a form? I can tell that validation is happening because I also have it bound to a button, but the decorators don’t activate until I type into the field

I'm pretty new and I'm sure this is not the best practice... but this worked for me to show errors immediately.

class SampleForm : View("Sample") {

    private val model: SampleViewModel by inject()

    init {
        runLater {
            model.validationContext.validate(decorateErrors = true)
        }
    }
 
    override val root = form {
        fieldset {
            field("sample: ") {
                textfield(model.sampleField).validator {
                    this.success("Woop woop")
                }
            }
        }
        buttonbar {
            button("Save") {
                enableWhen(model.valid)
            }
        }
    }
}

Awesome, thank you! I was trying something similar, but didn’t wrap it in runLater

Ya it doesn't seem to want to work in the init without it. I'm not sure why, maybe one of the more experienced people could shed some light on that 😛

you can accomplish the same thing inside of onDock without the runLater

Riiiiiight. I couldn't remember the name of the start up method. Thanks!
