Thanks for your help Igor. It worked like a charm.
For other readers new to wicket :
1. add an AjaxEventBehaviour("onclick") to the IndicatingAjaxFallbackLink
2. Override getCallbackScript to append the param values as described in the
email below
3. Do your server side processing in the onEvent method of the
AjaxEventBehaviour and not on the onSubmit method of the
IndicatingAjaxFallbackLink
Cheers,
Nim

override getcallbackscript(boolean) and return something like:
return generateCallbackScript("wicketAjaxGet('" + getCallbackUrl() +
"&myparam='+Wicket.$(<id of component>).value");
