DataTable: focus-tracker fails

[Benedikt Schlegel <co...@gmail.com>]

Hi folks,

is there anything i need to consider while setting up an DataTable with
FilterToolbar?

I have a FilterForm, added those 2 required hidden fields and everything
looks fine so far. But when i use the filter, the script fails setting the
focus on the 'active' field. I get a JS error
"document.getElementById(focused).focus() is null" but i dont know how to
fix that. Seems like the field does not exist at executing time.

Anyone else facing that problem? Anyone solved it?

So long,
Benedikt

Solved it by extending FilterForm:

public class FilterForm extends
org.apache.wicket.extensions.markup.html.repeater.data.table.filter.FilterForm
{
    private static final long serialVersionUID = 1L;
    public FilterForm(String id, IFilterStateLocator locator) {
        super(id, locator);
        super.remove("focus-restore");

        add(new AbstractBehavior() {
            private static final long serialVersionUID = 1L;
            @Override
            public void renderHead(IHeaderResponse response) {
                super.renderHead(response);

response.renderOnDomReadyJavascript("_filter_focus_restore('"
+getFocusTrackerFieldCssId()+ "');");
            }
        });
    }
}

Solution has been found in the wicket-users archives.
