Client Side Validation in ADF Faces

I will be going through a simple use case in this post to implement Client Side validation in ADF Faces components. By default ADF Framework provides quite a few validators which can be used while implementing use cases. Sometimes there is a need to create your own custom validators. This post explains, how to create a custom client side validator.
Validation can be of two types. Client Side validation and Server Side validation. Ideally there should be a check (validation) on both sever side and client side code.

I will be using JavaScript to code the logic of validator and will invoke this through ADF Framework class.

Cascaded List using ExecuteWithParams in ADF

Cascaded or dropdown list is one of them most common part of use case which is required to implement.
In this post we will create a cascaded dropdown using executewithparams.

Requirement :- Having two drop down list. Region and Country. On selecting region, country dropdown list should refresh to have countries of the selected region in the first list.

Retrieve selected value from selectOneChoice without writing a single line of code

While using selectOneChoice in the page to implement drop downs, it becomes very cumbersome to get the selected value from the list. One often has to write some lines of code in the managed bean to get the selected value from the drop down.


So in this post we will see how to get the selected value from the drop down list (af:seclectOneChoice) without writing a single line of code and without using any bean.

This uses the use of Variable Iterator which we discussed in the previous post.Variable Iterator in ADF to store values between requests

Variable Iterator in ADF to store values between requests

Variable Iterator is a powerful features provided by ADF which is being often not taken into consideration during implementation of Use Cases.

By Using Variable Iterator , variables can be saved between the requests and they can be refereed just by bindings name inside you beans. So using variables to store values between request is the way where variables can be accessed inside managed beans both having loose coupling between each other. You do not need to define a property(variable) inside a bean and bind it to the UI component.

So lets get started and see how we can use the power of Variable Iterator in ADF. We will be starting from the scratch and going step by step for clear understanding.
