do the jasperrepors masters have some idea of how to solve this issue??
I mean, it's a very usefull skill to perform actions or take decisions at outer levels of report (headers), based on whats going on with detail report data, not just to be able of draw things based on it
I've tried to solve it playing with subreports and retrieving values from them, but always face the same problem: variables placed at headers can't to react based on detail data
please let me know if there's some way to bypass this issue
Maybe I don't fully understand what you are talking about and a better example of what you need to achieve would be more appropriate.
But I just wanted to let you know that scriptlets are a very flexible way of implementing a complex data processing.
You could have a scriptlet that with every detail make the appropriate modifications of some internal data that you can then leverage at higher levels.
I hope this helps.

I have what I think is a similar problem to the original poster here. And it's not one that can be solved with the "Page i of n" trick.
I have a static set of lines that I want to draw on the background of every page... EXCEPT the last (summary) page. It would be extraordinarily useful to just set the "print when expression" to something like "$V{page_number} < $V{total_pages}" or the equivalent.
The best solution I have so far is to simply draw white lines over top of the background lines in the summary band.... which is, of course, a horrible solution.
Does anyone have anything better?

I've gotten around this problem by adding a column to my query that calculates the total number of rows in the recordset, then divide by the number of rows on a typical page. This gives me a good estimate of the total number of pages. I then use this field ($V{total_pages} = $F{cnt}.intValue() / 25) in my 'print when expression' (ie: print such 'n such if total_pages >10)
The query is similar to the following:
with t2 as (SELECT
count(acc.account_id) as cnt
FROM
account acc where amt>10000)
Select id, name, cnt from t2, account where amt >10000
The following thread might help you.

Hi!
I know this thread is a bit (well, quite) old, but just in case someone is searching for this issue. The easiest way to get the number of total pages is by defining a variable with the next attributes:
Name: total_pages (or any other)
Variable class: Integer
Calculation: highest
Reset type: report
Increment type: page
Variable expression: ${PAGE_NUMBER}I hope this may help.
