Re: Wicket.Ajax.post array parameters

public abstract class SortableBehavior extends AbstractDefaultAjaxBehavior
{

    @Override
    protected void respond(AjaxRequestTarget target)
    {
        StringValue prevValue =
RequestCycle.get().getRequest().getRequestParameters().getParameterValue("prev");
        StringValue draggedrValue =
RequestCycle.get().getRequest().getRequestParameters().getParameterValue("dragged");
        StringValue nextValue =
RequestCycle.get().getRequest().getRequestParameters().getParameterValue("next");

        update(target, parseIndex(prevValue), parseIndex(draggedrValue),
parseIndex(nextValue));
    }

    protected abstract void update(AjaxRequestTarget target, Long prev,
Long dragged, Long next);

    protected Long parseIndex(StringValue sv) {
        if (sv.isEmpty() || sv.isNull() ||
!sv.toString().matches("[0-9]+")) {
            return null;
        } else {
            return sv.toLongObject();
        }
    }


    @Override
    public void renderHead(Component component, IHeaderResponse response)
    {
        StringBuilder js = new StringBuilder();
        js.append("$(function() {");
        js.append("  $( '#"+component.getMarkupId()+" ul' ).sortable( {");
        js.append("    update: function( event, ui ) {");
        js.append("      var dragged = ui.item.attr('id');");
        js.append("      var prev = ui.item.prev().attr( 'id' );");
        js.append("      var next = ui.item.next().attr( 'id' );");
        js.append("      var callBackUrl = '"+getCallbackUrl()+"';");
        js.append("      Wicket.Ajax.ajax({ u: callBackUrl, ep: {prev:
prev, dragged: dragged, next: next}});");
        js.append("    }");
        js.append("  });");
        js.append("  $( '#"+component.getMarkupId()+" ul'
).disableSelection();");
        js.append("});");

        response.render(OnDomReadyHeaderItem.forScript(js));
        super.renderHead(component, response);
    }

here is a complete example with post exactly the same only you acces the
parameters with a like that:

StringValue parameterValue =
RequestCycle.get().getRequest().getPostParameters().getParameterValue("text");

I hope that's what you wanted
