Fix Version/s: 1.5-M2
(was: 1.5-M1)
> FilterForm requires focus-tracker and focus-restore be added as children in
> the markup
> --------------------------------------------------------------------------------------

> Key: WICKET-2467
> URL: https://issues.apache.org/jira/browse/WICKET-2467
> Project: Wicket
> Issue Type: Bug
> Components: wicket-extensions
> Affects Versions: 1.4.0
> Reporter: Steve Lowery
> Fix For: 1.5-M2
>
>
> When using a FilterForm, the following error is received:
> WicketMessage: The component(s) below failed to render. A common problem is
> that you have added a component in code but forgot to reference it in the
> markup (thus the component will never be rendered).
> 1. [MarkupContainer [Component id = focus-tracker]]
> 2. [MarkupContainer [Component id = focus-restore]]
> The tags have to manually be added to the markup to use the Filter Form.
> This could be the only way to get this component to work, but this would be
> the first component I've used thusfar where I was required to create children
> with specific ids in the markup.
> Here is the java code:
> public AbstractFilteredPanel(String id, T filter) {
> super(id);
> this.filter = filter;
> AbstractFilteredPanelDataProvider dataProvider = new
> AbstractFilteredPanelDataProvider();
> FilterForm form = new FilterForm("filterForm", dataProvider);
> add(form);
> AjaxFallbackDefaultDataTable<T> data = new
> AjaxFallbackDefaultDataTable<T>("data", getColumns(), getDataProvider(),
> getRowsPerPage());
> data.addTopToolbar(new FilterToolbar(data, form, dataProvider));
> form.add(data);
> }
> And the markup:
> <html xmlns:wicket="http://wicket.apache.org/";>
> <wicket:panel>
> <form wicket:id="filterForm">
> <table wicket:id="data"></table>
> </form>
> </wicket:panel>
> </html>
