I have a large screen divided into tabs. Because I reached the limit on number of controls, I've separated the controls for each tab into separate screens and when the tab is displayed I display the appropriate screen on the tab.
Some tabs have multi-column list boxes. The first time I bring up a record (any record), then click on a tab with a list box, the contents of the list box don't show. Data for other types of controls shows, just the list boxes are blank. If I bring up a second record, then the list box contents display and continue to display for every other record I bring up. However, if I now click to a different tab that also has a list box, the data in that list box doesn't show until I bring up another record. In other words, the first time a list box is displayed its contents do not show. Once I display the tab/screen with the list box on it and then move to another record, the list box contents display.
I am on 9.0.0. I have tried adding a specific DISPLAY of the list box when the tab is displayed (as opposed to just displaying the screen that contains the list box), but it doesn't change the behavior. Suggestions?
