When the system receives an error (for example, after a Save), it attempts to set focus
on the relevant widget, which might require flipping to a different tab page. If the
error relates to a list (grid or scroll) the system might not choose the tab page you
would prefer. In that event you can control the tab page that should be opened by
defining the TabMenu function
overrideErrorTabPage_<LIST_NAME>()
.
Example:
function overrideErrorTabPage_BPA() {
return 'bussProcessAssistantStepPage';
}
