Answer 1

This is a very common problem in dynamicReport, Whenever You use any component in detail, header or footer with the height or width more than page dimensions.

Try one thing, Divide your detail component in chunks of horizontalList components(divide them to maximum parts). I do this and handles them logically. You should prefer to you add

report.detail(cmp1);

and then

report.detail(cmp2); 

insteand of adding these 2 components in one component 'cmp' which contains both cmp1 and cmp2 , when you are not sure about height.
