The image shows the Expression Builder dialog in J Developer. The dialog contains a field called Expression at the top, where you can type in the Expression required. Below that, there is a dropdown called Variables and a node explorer with a search bar to search for variables. A list of Operands is on the right of the Variables section. At the bottom of the Variables section is a button titled Create Managed Bean.
In the node explorer, the J S F Managed Beans node is opened. Under that, the A D F Faces Context node is open, revealing all the variables contained in it.
At the bottom of the dialog, there is a collapsed Description box, and buttons marked Help, OK, and Cancel.
