Using PPR makes it really easy to render parts of your page on demand; however, in some use cases, it can become very hard to manage the PPR, especially with validations around.
For example, if you have a selectOneChoice
component that refers to a lookup table, you may want to provide the end user with a create button to create a new row in the lookup table, if it doesn't exist. Now that is a great feature, but if selectOneChoice
is the required field, then the create button will not be triggered unless the user selects a value of selectOneChoice
first.
Setting the immediate
attribute to true
will not solve the problem either, because it'll not change or execute the update model phase, which may be required.
ADF 12c provides a great solution to this problem by providing the Target
tag in which can be used to control the life cycle execution and rendering.
In this recipe, we have a very simple use case to be able to click on First, Previous, Next, or Last buttons...
