my case is:
there is a javascript variable (let say "var STATE;") that will be updated
througout the client side javascript event
there is a link (for example) that I want to use to pass the "STATE" through
ajax to server.
in your codes, does client side javascript method
"DnDSortableBehavior.asQueryString()" generate the query string and append
to the wicketAjaxGet? and you parse the parameters in the server side?
I think you have already given me good hints and I will continue work on
that, thanks very much
