Thanks for your fast answer !

When you say "never use expansions in  
component parameters", you mean this syntax 
<t:surveys.surveySuggestionsForm  surveyId="surveyLoopValue.id" /> 
is better ?


About the LoopFormState, I'm going to check this feature, I didn't know
it...
Do I have to change the LoopFormState of the loop of forms or the loop of
radio buttons ?

regards,
Antoine.
