Load Large Trees on Demand Use New Table Selection Change Behavior Question: Can I see the nesting of containers in the browserĪnswer: Use the key combination CTRL+ALT+SHIFT+O visualize the nesting in the browser in Web Dynpro screens. New in NetWeaver CE 7.1 Exchange default root view element (TransparentContainerUIElement) with other container UI element (like TabStrip, Table, Group) to minimize container nesting levels Instead, try to use a single large grid or matrix layout with column spans.Įxchange Transparent Root Container UI Element with other Container Types in CE 7.1
nesting transparent containers with matrix or grid layout inside other transparent containers also using these container layout types. Nesting has a big impact on browser or client rendering performance! E.G. Helps to achieve consistent layouts via predefined paddings (property cellDesign).Īvoid complex and nested layouts wherever possible. Prefer the Matrix layout to the Grid layout. Prefer the Row layout to the Grid or Matrix layout if you don’t need horizontal alignment (one column layouts).
Instead, control the layout using the layout property of the container UI element.
Main Objective: „Know to Tackle Web Dynpro Java Performance Gremlins as a Developer“Īpply Container Layouting Rules and Avoid Deep Container Nestingĭon’t add extra TransparentContainer UI elements inside container UI elements such as Groups – these UI elements already contain a TransparentContainer.

Web Dynpro Java Performance GuidelinesĢ.1. Overview of Web Dynpro Java Performance Aspects 2. This session is based on Web Dynpro Java in SAP NetWeaver CE 7.1 so that performance rules related to the newest Web Dynpro Java Ajax features like the different flavors of suggestion, asynchronous input validation or the new UI element event onChange are also considered.ġ. The given recommendations and best-practice rules focus on different aspects related to user interface design, component granularity, component and controller lifecycle management, controller contexts, on-demand resources, table paging or models like the Adaptive RFC model.
