Data management

Status: ✅ Implemented (Java; .NET/Python ports planned)

Intent

Section titled “Intent”

Present a data set two ways — a data grid and a Gantt timeline — on one dense, full-width page, with a toolbar switcher so the user can review it as a table or as a schedule. The Oracle Redwood Data management template.

How

Section titled “How”

Extend DataManagement and supply the two views:

@UI("/project-plan")
@Title("Project plan")
public class ProjectPlanBoard extends DataManagement {


    @Override protected Component gridView(HttpRequest rq)  { return theDenseTable(); }
    @Override protected Component ganttView(HttpRequest rq) { return theGanttCanvas(); }
}
  • The page lays out full width (PageWidthStyle.FULL_WIDTH).
  • A toolbar switcher (two buttons, labels via gridLabel()/ganttLabel()) flips the active view.
  • The active view is kept in state (_view, "grid" by default) and the page re-renders in place when the user switches — no navigation.
  • A heading (from @Title) sits above the toolbar; override heading() or return blank to omit it.

gridView is any component — typically a dense table (an embedded crud/listing, a fluent Grid, or @InlineEditing + @Compact for in-place editing); ganttView is typically a Gantt (the same canvas the GanttPage archetype uses). Pure composition of existing components, so it renders on every renderer without renderer work.

Demo

Section titled “Demo”

demo-admin-panel/.../datamanagement/DataManagementDemo.java (/data-management-demo): a project plan shown as a table and as a Gantt, switchable from the toolbar.
