How to get LOV value instead of index when it is used in “selectOneChoice” component in the table row?
When using LOV’s, a common issue in ADF is to get selected value instead of index when LOV is used to render for example “selectOneChoice” component. I’ve faced it when “selectOneChoice” was used in table. That means every row in table can have different selection of LOV values. Thus we can’t rely on iterators current row and simply to access…
How to make selectManyShuttle component work with nested table?
ADF can pretty easy handle Oracle DB nested tables in its components. In this post I will describe how it works with selectManyShuttle. Probably a similar behaviour can be used with other list components as well. I will use departments and employees tables of HR schema. Will create new column in departments with type of nested table. Then fill-in this…
JBO-25058: Definition vc_temp_1 of type Variable is not found in …
“JBO-25058: Definition vc_temp_1 of type Variable is not found in …”. What can be the reason? ADF creates/reuses application module (AM) instance for each user request. It is passivated (saved) after each HTTP request (if configured accordingly). When in application there are used some queries with view criteria, filter variables are passivated for according AM as well. During the next…
ADF “Select many shuttle” (af:selectManyShuttle) component does not show all items in the leading list
ADF “Select many shuttle” does not populate all items available in binded iterator. I don’t know whether this is a bug or some other reason, but af:selectManyShuttle in the leading list populates just no more items then defined in the “RangeSize” property of iterator. To my mind it supposed to fetch all items in iterator in bunches of %RangeSize%…
Problem with navigation using task flow actions – action is not executed after first button click
I experienced such strange ADF behavior regarding navigation using task-flow actions. Navigation doesn’t work after single button press. After second press – works fine. Preconditions: Application “MyApp” with two pages – main.jspx and popup.jspx (You can download sample app) popup.jspx belongs to bounded task-flow main.jspx belongs to unbounded task-flow Action “open” is defined in unbouded task-flow (see picture below) CommandButton…
How to implement contextual events between parent page and region?
Contextual events are necessary when need to communicate between separate regions or between parent page and region in ADF application. Here I’ll describe one approach to implement this. It is a little improvement of classic approach, because of event handling java interface is created and event consumer is implementing it. It is convenient, when need to separate data control implementation…

ADFDI-00502: The client was unable to establish an unauthenticated session with the web application. What can be the reason?
I have experienced such error. The reason was, that web application didn’t know, that servlet “adfdiRemoteServlet”, responsible for Excel workbook connectivity, should be secured. Problem happens only when ADF security is set to “ADF Authentication and Authorization”. This means, that ADF takes care not just for login, but for access to various resources (in our case it is adfdiRemoteServlet) as…
