Hi Teodor & Lucian,
and Lucian told me to post it as BugReport I do so now! :-)
Remaining space at page 1 = 50 pixel
next band in design = 60 pixel but all elements have "RemoveLineWhenBlank"... just one line is actually printed.... (no emtpy space between last element and bandbottom)
Jasper generates an empty page at the end just with pageheader/-footer band but without content. (as emtpy fields at the end are all removed)
PreRender elements and see if they all fit at current page and don't create new page break.
new method "checkForEmptyPage" where the current page is evaluated for some content placed on it... and remove the page if there is no content in any band (except the static header/footer bands).
It's hard to explain the users to create dummy bands to smallen the actual band from one big detail to many dummy bands just to avoid this behavior.
regards from Germany
PS: currently still using 1.3.4 in production... will upgrade soon to 2.0.X
