Hi, Thanks & just for the record... The second was using the first's value, via a CompoundPropertyModel, but that wasn't enough of a linkage to trigger a change. Updating the choice model on the onSelectionChanged gave me the behaviour I wanted though.
Having done that though, it was trivial to add Ajax support & move that to the onUpdate callback instead. There is one minor difference that I noticed in the Ajax/non-Ajax behaviours, which we might want to document if we can work out where to do so, i.e... When using a dropdown that was initialised to use a nullSelection string (e.g. "Choose One") and onSelectionChanged, when a choice is made the drodown gets reloaded. As it's no longer got a null selection, the "Choose One" string doesn't appear (which may affect the width of the drop-down if it was previously the longest option string). If AJAX is used instead, the dropdown doesn't itself get reloaded, so the nullSelection string remains (and can still be selected.) /Gwyn On 13/06/06, Igor Vaynberg <[EMAIL PROTECTED]> wrote: > all you have to do is in the onselectionchanged of the first change the > items that the second's choice model is pointing to, or change the choices > model entirely by calling setchoices > > take a look at the ajax example in wicket examples of the two drop downs, > take away the ajax behavior and it will work with a simple page refresh. > > -Igor > > > > On 6/12/06, Gwyn Evans <[EMAIL PROTECTED]> wrote: > > > Hi, > I've got a form with a couple of dropdowns, where the values in the > 2nd depend on the selection of the first.
