Oracle Tips by Burleson |
Page Item
Create a page item to hold a string value
indicating the function that has been initiated. For the demo, a page
item named P100_SEARCH has been created.
Button and Branch
A button named FIND_PERSON has been created.
Then, a branch was created to navigate to the global application page
to search for a person. The Action for the branch is shown in Figure
16.5. The conditional processing for the branch is set to execute
when the FIND_PERSON button is pressed as shown in Figure 16.6. This
shows navigation to APP 500: PAGE 200. This is the application id and
page id of the reusable page. The P200_FROM_APP_ID and P200_FROM_PAGE
page items are being set so the reusable page knows where to navigate
back to when a person’s name is selected.
Computation
The computations job is to set a page item to
indicate that a Find Person function has been initiated. This value
will be used by the processes when the page returns from doing the
search. This is done by creating an After Submit computation for the
P100_SEARCH page item. The page item will be set to a value of Find
Person. Figure 16.7 shows the Source and Conditions for the
computation.
