E0125: ui.State used with the wrong type

A ui.State[T] is a value the browser keeps current. It goes to a prop that takes a ui.State of the same T, and a chain's Set takes a T. A key can't read one. (A write's own types — open = !open on a bool, n++ on a number — are E0150.)

Wrong

<!-- menu.vuka.html -->
<script lang="go">
type Menu struct {
	open ui.State[bool]
}
</script>

<Label text={!open} />   <!-- Label takes a bool -->

Right

<!-- menu.vuka.html -->
<script lang="go">
type Menu struct {
	open ui.State[bool]
}
</script>

<Label text={!open.Get()} />   <!-- or: Label's Text a ui.State[bool] -->
