i find a bug of fetch value of suggestion box. i can reproduce it with richfaces demo.
in the example, when i type b, we have a list of state, at this moment, i continue type with spacer to add some white spaces after b, the list does not change. and then i select one in the list. finally in the inputbox, i get the name of the state i selected+ the white spaces i added. I think it is not a big problem, but it introduce the bug if we use this string as a key to search the object.
