I was having a delightful time using a common region defined on a global page when I determined that pagination setting was begin carried from one page to the next. Arghhhh! So for example, if I have paged to the second set (page) of rows (11-20) on Page 1 and then I go to Page 2, the second set (page) of rows (11-20) is displayed there. If I go to a page which only has a first set of rows (1-10), I get the pagination error "Invalid set of rows requested, the source data of the report has been modified. Reset Pagination". And when I click to reset, it just repeats the error. [I suppose it tries to display the second set or rows (11-20) again -- which doesn't exist. What's that saying about insanity?]
How can I decouple the pagination for a global region? I want it to operarate just as it would if it were not sharing a common region. So if I'm looking at rows (11-20) on page 1, I can go to any other page beginning with rows 1-10 there. Then return to page 1 where I left off with rows 11-20 displayed. One solution is NOT to paginate but that's not my preferred solution.
