HtmlSuggestionBox suggest = new HtmlSuggestionBox();
...

 HtmlActionParameter myActionParameter = new HtmlActionParameter();
 myActionParameter.setValue("abc");
 myActionParameter.setId("P42");
 log.debug("set assgin to");
 FacesContext context = FacesContext.getCurrentInstance();
 javax.faces.application.Application application = context
 .getApplication();

 javax.el.ExpressionFactory ef = application.getExpressionFactory();
 javax.el.ValueExpression ve = ef.createValueExpression(context
 .getELContext(), "#{Page.suggestid}",
 String.class);

 myActionParameter.setAssignToBinding( ve);
 HtmlAjaxSupport ajaxSupport = new HtmlAjaxSupport();
 ajaxSupport.setEvent("onsubmit");
 ajaxSupport.setAjaxSingle(true);
 ajaxSupport.setId(getID("a4jsupport"));
 myActionParameter.setParent(ajaxSupport);
 suggest.getFacets().put( ajaxSupport.getId(), ajaxSupport);
