fatbob Posted August 17, 2009 Share Posted August 17, 2009 Hi everyone,I have a report which has two subreports in the detail band. I can't seem to get them to print properly. I'd like to have the first subreport print, followed by the second subreport. The problem is that the second subreport is printing over the first subreport (have a look at the attached screenshot). The first subreport is the one boxed in red (titled Vital Signs), while the second subreport is boxed in blue (titled Clinical Measurements). Why is this happening, and how can I get the second subreport to print only when the first subreport has finished?Thanks! Link to comment Share on other sites More sharing options...
svenn Posted August 17, 2009 Share Posted August 17, 2009 Set the "Position Type" of the second subreport to "Float" Link to comment Share on other sites More sharing options...
fatbob Posted August 17, 2009 Author Share Posted August 17, 2009 I tried that, and what ends up happening is that the second report prints on every page, but not completely, parts of it print on all following pages. With the data I'm currently working with, the first supreport prints over three pages, so I'm expecting my second report to start printing on page 3, but when I set the second sub report to float I get what you see in my screenshot.I tried also setting both subreports to float, same effect.

Teodor Danciu Posted August 18, 2009 Share Posted August 18, 2009 Hi, Please attach the JRXMLs involved. It is not clear from the screenshots which are the subreports and how they are configured. Thank you,Teodor Link to comment Share on other sites More sharing options...
fatbob Posted August 18, 2009 Author Share Posted August 18, 2009 The master report is canCDERptCMDetail.xmlThe first subreport is canCDERptVSDetail.xmlSecond subreport is canCDERptOBDetail.xmlKeep in mind that the master subreport has another subreport, in the title band and another in the pageHeader band.

Teodor Danciu Posted August 18, 2009 Share Posted August 18, 2009 Hi, I don't see why the pages look so small in your screenshot. Have you manually edited the screenshot image?If so, it would be better to post the PDF version of the generated document. Thank you,Teodor Link to comment Share on other sites More sharing options...
fatbob Posted August 18, 2009 Author Share Posted August 18, 2009 The pages look small because I edited the images before posting them.I've attached a PDF of the report. As you'll notice, the second subreport (that prints the Clinical Measurements) starts's printing on page 2, but it should only start printing on page 3.

Teodor Danciu Posted August 18, 2009 Share Posted August 18, 2009 Hi, If you use a fairly recent version of JasperReports, I suggest you put the two subreports into different detail bands.Note that the detail section is nowadays a multi band section, so you could easily split it into several bands that behave the same way.What you see happens because the bands in the subreports are larger than the subreport elements as they appear in the master. So when there is some space left on the page, which is no sufficient for the bands in the first subreport to render, the engine starts to render content from the second subreport, because for those, the space left is enough.Clear separation of the subreports can only be achieved by placing them in different bands as suggested above.If multi band support is not yet available in the version of JR you are using, you can simulate additional details using dummy groups that break with every page because they have the REPORT_COUNT variable in their expression. I hope this helps.Teodor Link to comment Share on other sites More sharing options...
fatbob Posted August 18, 2009 Author Share Posted August 18, 2009 Unfortunately we are using a very old version of JasperReports, so I'm stuck with one detail band.Can you explain how I can go about using groups to simulate multiple detail bands? I tried playing around with groups very briefly and it didn't work for me. For example I created a group, added one of the subreports to that group's band and that subreport didn't print at all.BTW, thanks for the help you've been providing me, much appreciated.

Teodor Danciu Posted August 18, 2009 Share Posted August 18, 2009 Hi, The <detail> band of a report works the same way as the <groupFooter> band of a group that has: <groupExpression>$V{REPORT_COUNT}</groupExpression> Create two such groups and use their group footer bands to put the two subreports.The actual detail band can be missing or empty. I hope this helps.Teodor Link to comment Share on other sites More sharing options...
fatbob Posted August 19, 2009 Author Share Posted August 19, 2009 Wow, thanks a lot! The groupFooter did the trick!The only odd thing is that in this example, my first subreport prints on 3 pages, and the second subreport starts on the third page, and then restarts on the fourth page. Why is it partially printing on the third page?Also, just curious, but is there a way to have the title (for example "Vital Signs"), print only once? Right now as you can see from the PDF, it prints on every page. How can I get it to print only once?I've attached the lastest version of my master report and a PDF.

Teodor Danciu Posted August 19, 2009 Share Posted August 19, 2009 Hi, The title prints on every page because you have used the page header section of the subreport. If you would have used the <title> section, it would have appeared only once.The second subreport starts on the third page because the remaining space there is enough for the title and headers to fit. So why should the engine waste any space, if you did not tell it not to? You could prevent this if you would use the minHeightToStartNewPage property of the dummy groups you made to replace the detail. I hope this helps.Teodor Link to comment Share on other sites More sharing options...
fatbob Posted August 20, 2009 Author Share Posted August 20, 2009 Hi teodord,I must be doing something wrong (or I'm missing something), but no matter what I set minHeightToStartNewPage to, it's still giving me the same results as you see in that PDF I uploaded. I even tried setting isStartNewPage to true, and still part of my second report prints on page 3.What am I doing wrong? Link to comment Share on other sites More sharing options...
Teodor Danciu Posted August 21, 2009 Share Posted August 21, 2009 Hi, You uploaded a JRXML not a PDF. Now that you mentioned it, I agree it might not work, as for the nested group, the page is already considered new.Not sure how to solve this. If you want to, you could log a bug or a feature request on our trackers so that we try do something about nested groups forcing a new page. Thank you,Teodor Link to comment Share on other sites More sharing options...
fatbob Posted August 27, 2009 Author Share Posted August 27, 2009 Hi teodord, Sorry for not replying sooner, but I got sidetracked. I would report it as a bug or enhancement, but the thing is that I need to finish this report ASAP. It needs to go in prod in a few weeks time. Is there some other work around that I can use to force a page break, or force it to use the minHeightToStartNewPag? Maybe you know of some trick or something to allow this to happen? Thanks! BTW, I attached the PDF that I was supposed to attach on my last post.Post Edited by fatbob at 08/27/2009 17:50 Link to comment Share on other sites More sharing options...
Teodor Danciu Posted August 28, 2009 Share Posted August 28, 2009 Hi, There is no workaroud, if you do not upgrade to newer JR. Thank you,Teodor Link to comment Share on other sites More sharing options...
davidetau Posted September 17, 2009 Share Posted September 17, 2009 Hi teodord,I use the latest version of JR, so I wish to use the multiple details bands for subreport instead of dummy groups, but in this way how can I have something like the property isStartNewPage of dummy groups?Thanks Link to comment Share on other sites More sharing options...
Teodor Danciu Posted September 18, 2009 Share Posted September 18, 2009 By putting a page break element at the top of the band or of the subreport?If you want to prevent an unnecessary first page break, you would use its printWhenEXpression to test the PAGE_NUMBER variable. I hope his helps.Teodor Link to comment Share on other sites More sharing options...
davidetau Posted September 18, 2009 Share Posted September 18, 2009 Hi,I've just tried page break in each band starting, but it seem doesn't work, maybe I'm missing something.. I attach my report file (Modulo19.jrxml) with subreports (Modulo8.jrxml, Modulo16.jrxml and Modulo17.jrxml) and the resulting pdf (Modulo19.pdf)As you can see Modulo8 subreport (titled "Consulenze") Modulo16 (titled "Problemi clinici") and the header of Modulo17 (titled "Diario clinico") are printed in the same page, nevertherless the break elements in their respective bands... what I am missing?Thanks Link to comment Share on other sites More sharing options...
davidetau Posted September 21, 2009 Share Posted September 21, 2009 I've found why page break didn'd work. I used it at the top of the band:<band><break>.....................</break><subreport>...................</subreport></band>and it didn't insert any new page before subreport.But if I add some element before page break, for example an empty static text:<band><statictext>...............</statictext><break>.....................</break><subreport>...................</subreport></band>it works properly. Is this the usual behaviour of <break> tag? Link to comment Share on other sites More sharing options...
Teodor Danciu Posted September 21, 2009 Share Posted September 21, 2009 Hi, It indeed looks like a bug. Please log it on our project trackers. Thank you,Teodor Link to comment Share on other sites More sharing options...
Teodor Danciu Posted September 21, 2009 Share Posted September 21, 2009 Hi, I have tested this again and it is not quite a bug. The page break element does not work if it is the first element in the band and the band is the first band on the page. This is probably why it does not seem to work for the first occurance of the subreport. Thank you,Teodor Link to comment Share on other sites More sharing options...
davidetau Posted September 21, 2009 Share Posted September 21, 2009 Hi,Thank you for your reply. In my case I have actually more than one detail band, but if I put break element as the first in any band,not only the first band, it doesn't work. I solved it with the trick of an empty text box before break.Post Edited by betel at 09/22/2009 08:51 Link to comment Share on other sites More sharing options...
