A page process performs an action at a specified point during the rendering or submission of the page. For example, you can create a page process to execute logic or to make a call to the Application Express engine. A page process is a unit of logic that runs when a specific event occurs, such as loading or submitting a page.From a functional perspective, there is no difference between page-level and application-level processes. The difference between these two process types is where the process is defined, that is at the page-level or at the application level. You can define both success and error messages that display when a process runs.
How an error message displays depends upon the processing point. For processes with a processing point of On Submit - Before Computation and Validations or On Submit - After Computations and Validations, you can specify whether the error message displays inline on the current page (the default) or on a separate page. For all other page processes, error messages display on a separate error page.To create a page process error or success message:. View the process attributes in the Property Editor.
Edit the following attributes:. Success Message, Success Message - Enter the success message for this process. If the process runs and does not generate an error, then this process success message displays in the notification section of the resulting page displayed.
If you are branching to another page via a URL redirect, you may need to check the preserve success message attribute. Error, Error Message - Enter the error message for this process. This message displays if an unhandled exception is raised.
After any error processing stops, a rollback is issued and an error message displays. Error, Display Location - Select where this process error message displays, when the process fails to complete successfully. To create a conditional page process, edit the following attributes:.
View the process attributes in the Property Editor. Under Server-side Condition, edit the following attributes:. When Button Pressed - If you want this page processing component to execute only when the specified button is clicked, select a button from the list. You can incorporate this button condition with other conditions to further refine when this page processing component executes. Execution Scope - Applicable only to editable interactive grids. Specify the execution scope.
