From GeneXus 8.0 RC: Transactions as Web Components

In the new GeneXus version, in addition to web panels, transactions can also be defined as web components.

The definition of transactions as web components enables reuse of this code that is displayed in web interfaces and facilitates consequent maintenance of web applications.

Let us remember that web components may be run independently or may be part of another web object -web panel or web transaction- granting GeneXus web-application designers a high level of code reuse.

The possibility of defining a transaction as a web component enables display of several components in a web panel. Some will contain transactions (for additions, deletions, and data modification) and others will contain web panels that will show related information, menus, etc.

In the following image, for example, you can see the grid where the names and addresses of clients are shown, and below, the transaction defined as web component, where this information may be modified.

How is a transaction defined as a web component?
The definition and use of a transaction as a web component is similar to that of web panels as web components.

For more information refer to the document on web components.
