Oracle Tips by Burleson

Creating a Branch

Creating branches is accomplished from the page definition page.  The imaginary example shown below will create a branch to a page, clear the cache, and send two values to set page items.

1.       Click on the  in the Branches area under Page Processing.

2.       On the Point and Type page:

• Select the Branch Point:  this example uses On Submit After Processing.

• Select the Branch Type:  this example uses Branch to Page or URL.

• Click Next.

3.       On the Target page enter the appropriate information and click Next.  Figure 12.5 shows the Target page for this example.  Notice the use of the &ITEM. notation in the With these values field.

4.       On the Branch Conditions page:

• Set the Sequence for the order in which the branches are to execute.

• Select the correct item for When Button Pressed if this branch should only execute when a particular button is pressed.

• Select a Condition Type, if appropriate, and fill in the proper Expressions

• Click Next.

5.       If there are two or more buttons that the branch should respond to, the When Button Pressed option cannot be used.  Instead, use a Request Is Contained within Expression 1 condition type and enter the names of the buttons in Expression 1, such as CREATE or EDIT.  Then the branch will be executed for either of the two buttons.
