Re: 5.4 List inside form is failing Could not find a coercion from type java.lang.String

[Lance Java]

The loop / ValueEncoder are used to serialize the values that were used to
render the form. This is used to re-hydrate the initial form state when the
POST is received. If you are happy to re-lookup the values (or the values
are static) then it is fine to use formState="none". If you don't want to
re-lookup the values on POST or want to know what values were presented to
the user then a ValueEncoder is best.
