Type Converter question
When refreshing a form, I get the error: "No type converter for type
TypeABC"
My question is: Why does Tapestry (4.0) invoke a "type converter". What
does Tapestry use it for?

Thanks Howard.
So, a TypeConverter converts a string (e.g., the string-representation
of some Object, for example, something persisted client-side) into the
Object.
Am I right in assuming that the Object's type is added, so the correct
TypeConverter can be chosen? Also, by what mechanism is the Object
converted to a String (in the first place)?

Chances are good this is related to a client-side persistent property,
or a
property stored inside a form using Hidden.
A type converter is most likely being used to convert from a string to
some
server-side type. Perhaps you tried to update a property that is really
an
entity type?
A stack trace would help narrow it down.
