Hi,
I have form, and a list that is being populated with it. When I first enter
the action the list populates properly. But the second time, I get the
following error:
tag 'select', field 'list', name 'country': The requested list key
'countries' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]

It seems like the countries object has been poped off of the value stack
during the validation firing, any ideas how to fix this??
The tag is as follows:
<s:select id="registration_countryCode" name="country" multiple="false"
emptyOption="true" required="true"
list="countries" listKey="code" listValue="name" label="Country"
>
thanks,
