How do I handle pagebreaks with nested DWs in trailer or summary band?

I am using PB12.5.2 Classic. My report has nested datawindows in trailer and summary bands, which works fine except that where there should be a page break in the trailer or summary bands, the final page is neither displayed nor printed. I have tried autosized or fixed heights for the bands, but the problem is the same with both (though really my report requires autosized). Looking on the net, it seems that an issue was raised for this in PB9.0. Has the problem been solved in PB12.6 or is there some work around that would work with PB12.5.2?
