Today I had to fix an issue in one of our ADF applications. For those of you working with ADF (as I do too occasionally) this might be valuable, so I decided to share this. The application is based on an old Oracle Forms applications and I had to implement the following functionality:
FRM-41830 : List of Values contains no entries.
In other words (more ADF like) : If you are about to render a List of Values and that List of Values contains no rows, just show a message instead of showing the List of Values.
In this post I will describe how I was able to implement this although it turned out to be a challenge.
Below are the steps that I took. Note that the Application can be downloaded from GIT.
1) I use a UI pattern where we use readonly table and do edits in a popup. That means that any List of Values will add an additional popup to the UI. Read the complete article here.
