After reading the documentation for LoopFormState, I found that ITERATION is
the value I want in my case.
"When the Form is submitted, the Loop will re-acquire its source and iterate
over it"
But when I used this value in my loop component, an new error is throwed :

Here is the code of my Survey.tml
<t:form t:id="survey_form">
<t:radiogroup t:id="suggestionRG" value="selectedSuggestion"
encoder="suggestionEncoder">
<t:loop source="suggestions" value="suggestionLoopValue"
formState="literal:ITERATION" encoder="suggestionEncoder">
<t:radio t:id="radio" value="suggestionLoopValue"/>
<t:label for="radio">${suggestionLoopValue.label}</t:label>
</t:loop>
</t:radiogroup>
<t:submit id="surveyVote" t:id="vote"
image="context:images/vote_button.gif" />
</t:form>
This component was included into SuperComponent :
<t:loop source="surveys" value="surveyLoopValue" encoder="surveyEncoder">
<t:surveys.survey surveyId="surveyLoopValue.id" />
</t:loop>
Am I missing something ???
Regards,
Antoine.
