The Application Express engine dynamically renders and processes pages based on data stored in database tables. To view a rendered version of an application, you run or submit it to the Application Express engine.
Tip:You cannot run Modal and Non-Modal dialog pages directly using the Save and Run Page button. To view a Modal and Non-Modal dialog page, run the normal page that is responsible for opening the dialog page and access it from there.
To run a page in Page Designer:
View the page in Page Designer. See "Viewing a Page in Page Designer."
You preview a page by running it. Running an application page displays the rendered version as end users would see it.
Click the Save and Run Page button in the upper right corner. The Save and Run Page button resembles a blue right-facing arrow.
A rendered version of the application page appears.
