Not entirely following... at least in trunk:
From AjaxFormLoop:
ValueEncoder defaultEncoder()
{
return defaultProvider.defaultValueEncoder("value", resources);
}
Hidden:
ValueEncoder defaultEncoder()
{
return defaultProvider.defaultValueEncoder("value", resources);
}
RadioGroup:
final ValueEncoder defaultEncoder()
{
return defaultProvider.defaultValueEncoder("value", resources);
}
And, for the record, Grid (to demonstrate the fact that Grid is default the
same way):
ValueEncoder defaultEncoder()
{
return defaultsProvider.defaultValueEncoder("row", resources);
}
But it does appear that Palette and Checklist are not proving a default
encoder, and the why behind that I don't know.
