Problem with the total page-function [message #677045]

Hi,
I'm using BIRT 2.6.2 and have a problem with the total page count. Sometimes it shows the correct number, that is the actual number of pages the end report consists of, and sometimes it shows a higher number.
Example:
The end report (pdf): 7 pages
In the header of each page:
1(9)
2(9)
etc. up to
7(9)

Is there any way around this problem? I've read a rumour of a similar bug that should be solved in the upcoming new release of BIRT, but unfortunately I need to solve this in version 2.6.2.

Background:
The last months I've been working on upgrading BIRT to 2.6.2 and one of the changes I've made is switching from RunAndRenderMethod to using RunMethod and RenderMethod separately. This to enable the use of the page count method and adding an empty page when needed.

Can you reproduce the issue with the sample db and post the report?

I sent an example report last wednesday by email and I am now wondering if there is any news on this subject?

Sorry for the delay. I did not see it when it came in. I just
responded to your email. I think the issue is that the total page
variable is getting clipped.

Ah, I see. That means I didn't succeed in reproducing the problem in the report connected to the sample db. The problem still exists in the original report so I will try to reproduce it in another way.

Unfortunately I have still not been able to reproduce the total page number problem when I read data from the database.
I have found something else that affects this problem. Some of the report items uses Page Break = avoid. I noticed that the report had avoid on several layers within one list.
For example: A list containing a grid containing rows, and Page Break = avoid is set on all 3 layers.
When I change all the "avoid" to "auto" the total page number is correct!

Question 1. Is there any known problems with the page break property?
Question 2. What's the recommended way of using the avoid value? On top-level only?

This sounds like a bug. Can you open a bugzilla entry for it?

Hi again!
Now I know exactly what the problem is! Under the Visibility property I select the Hide element and state an expression, then the page total is wrong in the end pdf report. I include an example report connected to the sample db and that shows the problem.

My question then becomes: What is the solution to this?

Regards
Aca

ps. As you will see i the example report this has nothing to do with page break and avoid property which I thought before. I have not entered a bugzilla entry.

Additional information:
It might be interesting to know that the page total shown on the pdf IS correct if I use the RunAndRenderTask in the engine.
When using RunTask and RenderTask separately the page total is incorrect due to the visibility problem. I was earlier informed of the getpageCount() (from IReportDocument) which can only be used together with RunTask and RenderTask, and that function displays the same erroneous total as is shown on the pdf report.
(This is in BIRT 3.6.2)

Can you add your comments to this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=331541

I think this is a problem with fixed layout. All output formats have
the same number of pages when using a run task and then a render task.
You can switch to auto layout but this is probably not what you want.

Hi there,

we have the same exact problem in BIRT 2.6.2

As I understood from the bug no. 331541 (comment 12), this is a design problem in BIRT.

Did you find a workaround for this?

I do not know of a work around to this problem (with the exception of
writing two reports), but please add your comments to the bug.

Hi,
I have actually found a work around, but it is not connected to BIRT. As my end result always is a pdf-report I use the getNumberOfPages on pdfReader instead. That way I can render the report with RunAndRender in BIRT which gives a correct pagenumber in the header. After the rendering I can count the actual number of pages with pdfReader and insert empty pages when needed.

As this is a work around in pdfReader I have not added this to the bug. Let me know if I should add it anyway.

I would like to see this as a dev share item in BIRT-Exchange.org, if
you have the time. Then you could update the bug to point to the item
to show how you worked around the issue.

I'm sorry but I don't know what a dev share item is.

The steps I have added in the ReportEngineService are the following...

1. Create the report with createRunAndRenderTask(report) which results in a byteArrayOutPutStream. (This is standard code, but I include this step as a background for the following steps)
2. Convert the byteArrayOutPutStream into an byteArrayInputStream and create a pdfReader object.
PdfReader reader = new PdfReader(new ByteArrayInputStream(baos.toByteArray());
3. Get number of pages from the reader and use it
int pageCount = reader.getNumberOfPages();
if(pageCount%2>0){ //add an empty page }

Thanks. A devshare item is just an example that is posted on
birt-exchange.org's dev share. If you look here:
http://www.birt-exchange.org/org/devshare/

You will see a lot of BIRT examples (Reports, articles, example APIs, etc)
