Assign with no transition has "ssign" or "" as target

[yoav-lavi]

Hey,
Noticed that if you try to make a transition containing only an assign action, it adds a "ssign" target if no other state is defined, or "" if another state is defined (whereas I would expect no target in such a case)

state initial {
  TEST => assign(someValue)
}

The resulting code is

import { createMachine, assign } from 'xstate';

export default createMachine({
  states: {
    initial: {
      on: {
        TEST: {
          target: 'ssign',
          actions: [
            assign({
              someValue: (context, event) => event.data
            })
          ]
        }
      }
    }
  }
});

And when doing the following:

state initial {
  TEST => assign(someValue)
}

state other {}

The resulting code is

import { createMachine, assign } from 'xstate';

export default createMachine({
  states: {
    initial: {
      on: {
        TEST: {
          target: '',
          actions: [
            assign({
              someValue: (context, event) => event.data
            })
          ]
        }
      }
    },
    other: {

    }
  }
});

I'm aware that Lucy is in alpha and issues are to be expected, just wanted to give you a heads up :)

Good luck!

Thanks! Yes this is indeed a bug. I'm curious if we should require a target state at the end of a transition or should we implicitly transition back into itself?

This is fixed in 0.1.5, thanks a lot for bringing the issue to my attention!
