Duplicate usage of view

[Former Member]

Hi.

I saw this issue discussed in a thread a few years ago, but do not see how it was resolved.

The question was: I have a view with 2 ViewContainerElements and I want both of them to contain the same view with different data.

The suggestion then was to wrap the common view in a component of its own and then use "external mapping" to reference that in the main view.

What exactly does this mean.

I'm familiar with External Context Mapping in which context attributes may be used in other components, but can a whole view from one component be embedded in such a way in another view, and my particular question is - can a view be embedded in that way multiple times in another main view?

Thank you,

Dina

Hallo Dina,

see my tutorial/sample application pack on Web Dynpro Java View Compositions

This Web Dynpro sample application implements a complex view composition. The term view composition describes a set of all view assemblies that can be accessed by navigation. A view assembly consists of normal Web Dynpro views and interface views of Web Dynpro components within the browser window. You can model view compositions in the Navigation Modeler as part of the Web Dynpro tools.

The following options are applicable to model view compositions:

• Embedding several views in view sets

• Embedding view sets in each other

• Embedding visible Web Dynpro components using their component interface views

• In this tutorial, a Web Dynpro component is embedded using two instances.

• Embedding views and view sets in view layouts by using the ViewContainerUIElement
