Understanding Nested Application Modules in Oracle ADF

Application Module acts as a container for view Object and view Link business components that are used in a specific task. It provides data model and data control to show required information and perform action for the client
An application module represents a single transaction and owns one database connection that's why commit and rollback works for all view Objects inside an application module

Check for dirty (Uncommitted) data of current view port (page) on a button click or any event in ADF

Sometimes we need to check for uncommitted data on page and perform actions according to that, Suppose there is a button to navigate to another page but only if there is no uncommitted data in current page
We can use uncommitted data warning property of af:document to show an alert dialog but in that way, we can't execute our custom logic

Previously I have posted about checking dirty data of a transactional data control but in that, we need to check that for each data control separately that is rendering on page

ADF Basics| Tip to Hide af:inputListOfValues search popup at runtime

Hello All

Previously I have posted about a requiremnt of  hiding af:inputListOfValues search icon using CSS
ADF Skinning | Hiding search icon of af:inputListOfValues using CSS & StyleClass

In that solution search icon doesn't appear on page but it is a part of JSF component tree so when user press TAB+SPACE after entering a value in lov component then search popup appears on screen as this action invokes search icon click event

Recently a Friend of mine came across another requirement that was not showing lov popup at all as only autoSuggest behavior was required , so for this first way is to use autoSuggest behavior in an af:inputText compoent using Lov bindings and second way is to short circuit component life cycle
