Hi! I'm working on a react web app based on the kotlin full-stack example. 
i experienced a strange error when using setState in a lambda function. I found a workaround, but I'm still curious why this happens.

Here i have 3 examples of how I change the 'teaser' variable which is a String in all 3 cases.

InputField {
  this.value = state.job.teaser
  //this works
  onChange = { e -> setState { teaser = e.inputValue } }
}
InputField {
  this.value = state.job.teaser
  // throws "cannot set property 'teaser' of undefined"
  onChange = { e -> setState { job.teaser = e.inputValue } }
}
InputField {
  this.value = state.job.teaser
  //this works
  onChange = { e -> setState { ref.state.job.teaser = e.inputValue } }
}
