It seems that if a variable is present in the request multiple times the value is set using comma's to seperate the different values... Strange!! I posted the issue on the Spring forum, but no response yet... -- After conducting some test the above seems to be a feature. If the source value is of type array (which is the case when multiple identical params are posted) and the target value isn't the binder tries to convert the array into the target type! If the target type is an array everything is fine! Hmm,
