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. 2) The List of Values that I use in this sample only shows entries where the minimum salary is less then the employees current sal...

In this post I describe how I implemented an interesting Use Case where the customer wanted to have an alternate message in the LOV when there is no data found. We all know how this can be changed in an af:table component by simply changing the emptyText property. In a List of Values, this works 'slightly' different. Lets start with the basics By default you will see the following List Of Values, telling you that no data was found: However in the case of my customer, they were not happy with the text. So I had to come up with something else. That is interesting, because the ListOfValues is an ADF component in itself and the individual components inside the LOV cannot be manipulated by means of properties. I had to find a way to get access to the table component inside the List Of Values. The way to do this has been described by Frank Nimphius, a long while ago, in his Forum Harvest posts. To be more specific, it is the harvest of November 2010, section " How-to def...
