SecurityContext TaskFlowViewabe in ADF

Many times in our ADF Applications, we create Module workspaces which are specific to module and use these workspaces as ADF Shared Libraries in the Master Application. Master application has JSPX pages which uses adf task flows from shared libraries as regions in them.

While enabling ADF Security and granting permissions, authorizations are given to only Pages and task flows. There are other components on the page which also requires authorizations. For example Widgets/Buttons/Headers ,they should be shown to the user only when they are authorize to.

So for the above said use case, most common solution is SecurityContext which is provided by ADF Framework. Below code is being set to rendered/visible property.

Attributes in Page Templates ADF

In most of the applications, one of the most versatile reusable component that is being used is Page Templates. Page templates serve as a generic component which is used to define the structure and layout of the pages.

There are many use cases where there is a requirement to have different behaviour for some of the pages than rest of the pages using the same Page Template. In this scenario, the components for which different behaviour is required are made parametrize. These parametrized are provided in the form of attributes. These are simply variables which can be set in the Page which is using the Page Template having these variables.

Use Case : In this use case, we have a requirement that some of the pages should show error messages on the top of the adf editable form, while some pages should not show error message on top.
