I´m not sure I´ve I understand you in the right way. Updating one Component
is not the problem, I stillt tried taht and it works.. I want that my
ContainerElement includes the "@Form" and in the Form tag the dynamic
Number of Components is included. So the ConatinerElement have to take care
of binding and updating the values of the Subcomponent.
