A perspective can show one or more views simultaneously. Depending upon the application requirements, the number of views that are simultaneously displayed views may change in response to events occurring within the application. Application developers may force views to maintain a specific size or location, or to remain open, when displayed in the perspective. Alternatively, application developers may allow users to close views. While the Lotus® Expeditor workbench application enables the ability to “reset” a perspective to its initial configuration, you may want to also provide menu options that enable users to open specific views if they are inadvertently closed.
If your view is to be used in Composite Applications or has multiple instances on a single perspective, then you must specify the attribute allowMulitple=true
in your view extension declaration.
