PHP Warning: Undefined array key in PrefillMultiFieldViewHelper.php line 209

@lukaszuznanski, I stumbled upon this issue again and tried to make sense of what's the real problem here.

Maybe you can help me understand this excerpt from the check/radio/select/country field partials:

    <headlesspowermail:form.registerField property="{field.marker}."
                            value="{setting.value}"
                            checked="{vh:misc.prefillMultiField(field:field, mail:mail, cycle:index.cycle)}"/>

It's used to create the trustedProperties, right? E.g.

{
  "name": "tx_powermail_pi1[__trustedProperties]",
  "value": "{\"field\":{\"anrede\":1,\"vorname\":1,\"nachname\":1,\"strasse\":1,\"hausnummer\":1,\"plz\":1,\"ort\":1,\"land\":1,\"country\":1,\"email\":1,\"newsletter\":[1]}}34a29410e84c1f4afb07b7d002fda0503bde9b3f"
},

Why does headlesspowermail:form.registerField have to have the parameters value and checked though? In my opinion that's not necessary at all.

And checked is using the prefillMultiField viewhelper with a wrong cycle parameter, what's the intention behind that?

The problem occurs only when running into a serverside validation error and the form is being rendered again. It's the checked argument that is causing the problems and I'm convinced now that it's not necessary at all. In my project I've removed them and it's not causing any problems anymore...

Removing the attributes checked from the viewhelper "call" didn't solve all problems. So I super-simplified the RegisterFieldViewHelper to the bare minimum, see #37

I cannot see why this viewhelper was so complicated in the first place. Maybe left-overs?
