Custom filed throws a YSOD

[eriksimonic]

Hi. I have a custom field configured like this.

<Field type="ap.package.selector" name="Package selector" fixedValues="true" />

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.String[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'pages[0].rows[0].cells[0].fields[0].submittedValues', line 31, position 20.

Hey @eriksimonic,

Argh I hoped I had beat everyone to that bug. I released a fix for it last night, check the most recent release.

[eriksimonic]

@kjac

+1 problem
Version 0.15.1.2. has this problem, FormEditor.config is the same as before..

[kjac]

@eriksimonic I'll have a look at it. Looks like the field type is not being deserialized.

[kjac]

@eriksimonic The latest release (0.15.1.3) should fix the problem.
