ADF Code Corner: How-to pass values from a parent page to a popup dialog

By frank.nimphius | November 4, 2009

To display values of the current table row in a popup dialog, or read current row data values in Java, developers use a simple but effective binding trick: To access the values of a selected row, you create attribute bindings for all attributes of interest of the iterator that the tree binding, which populates the tree at runtime, is based on. Because tables synchronize the selected table row with the binding, the attribute bindings always provide access to the row values using #{bindings..inputValue}. This little trick comes with no additional cost and also has the advantage that you can use the Expression Language builder in Oracle JDeveloper to bind UI components to the values. The disadvantage of this approach is that a row must be current – selected – for the popup to display the correct values or Java to be able to read these values in. Use cases, like multi row selection or displaying detail information fro a row, require a special handling if the information should be for non-current rows as well. In the example explained in this article, I use a table that displays a note window when the mouse hovers over a text label in the last column.
