I need to build a page where I have a tree on the left side of the page, and extended information about the selected node on the right side of the page.
Coming from a PL/SQL world, I have no idea to to make this work. I built the tree and used a form wizard to render the extended information. I used thread
10308684 to copy the ID of the selected node into the ID column of the form. Now, I need to requery data from the database and re-populate the form. How to do it? Population of ID column of the form does not seem to trigger any event where I could have added on-demand processes; or I am looking in the wrong direction.
