Using JDeveloper 12.1.3:
I have af:table inside af:panelCollection inside an af:gridCell. Cell is width 100%, panelCollection is AFStretchWidth style.
Table is too wide to fit the page width. So there should be a horizontal scroll bar. It is there if there are enough rows in the currently queried set that it needs a vertical scroll bar. But if there is no vertical scroll bar needed, the horizontal scroll bar is also missing. You can't see the columns that are right of the frame. Oddly - there is an exportCollection listener and if you export to Excel, you can see all the columns. Also, if you use the panelCollection's Detach function and show the table in a pop-up, the horizontal scroll bar is present in the detached table, and you can scroll to the rightmost columns.
I have a test application based on the HR schema, and I can't make it malfunction the way the real application does. Scroll bars appear when they should.
So I must be doing something wrong in the real application. Any thoughts?
