GWT with UIBinder - how to programatically add ScrollPanel?

Question

i want to programatically create scrollPanel inside

    <g:FlowPanel ui:field="viewDynamicContent"></g:FlowPanel>

Code for scrollPanel generating is as follows:

    ScrollPanel scrollPanel = new ScrollPanel();
    FlowPanel flowPanel =  new FlowPanel();

    scrollPanel.addStyleName("standard-scroll-panel standard-content-bckgr");

    final HTML emptyInfo = new HTML();
    emptyInfo.setHTML(new SafeHtml() {
        @Override
        public String asString() {
            String html = "";
            html += "<div>";
            html += "<p>" + SEARCH_EVENTS_LIST_EMPTY + "</p>";
            html += "<p>";
            html += "<span class='font-color-cyan'>" + SEARCH_EVENTS_LIST_EMPTY_2 + "</span>";
            html += "</p>";
            html += "</div>";

            return html;
        }
    });
    emptyInfo.addStyleName("standard-warning-panel text-center");

    flowPanel.add(emptyInfo);
    scrollPanel.add(flowPanel);

    viewDynamicContent.add(scrollPanel);

The problem is, i can get proper html structure with this code but unfortunately i can't scroll. After moving scrollPanel in any direction, it's always coming back to default position. After adding ScrollPanel widget inside HTML structure everything is ok, but in this specific case i need to completely create this element inside java function.

You have to set size of ScrollPanel in some way, either setting in explicitly or putting ScrollPanel inside some panel which ProvidesResize.
