We have a multi select component which is bound to a List<T> in our model. The binding is working well.
The problem is when no element is selected. Then the binding is not made to the List<T> and if the List was previously containing elements, they are not removed since Spring Web Flow don't know it should bind an empty list to the model and since the model is not recreated at each POST (like in Spring MVC with SimpleFormController).
I expected to have a configuration in the flow.xml to force the binding but I couldn't find anything.
I'm still looking for a solution. Has anybody any solution ?
