Hi,


I have just upgraded Aspose JasperReports to 2.7.2, the NullPointerException is gone, but a blank page appears inside the exported dcument.
No issue with the native JR exporter with the same report.

I attached the jrprint list and the docx output to the post : jrprintList.zip

Thank you

Hi Jerome,

I am developer who works on this issue right now.
Could you please try to set following config option in your code:

exporter.setParameter(AWExporterParameter.SPACING_FACTOR, 0.1);
Please let us know whether it fixed the issue.

You can read more about this option here - Spacing Factor


Thanks and regards,

Hi Jerome,

Thanks for additional info.

Please let us know also:
1) what version of Office do you use?
2) do you see [Compatibility Mode] on top of Word window while opening generated report?
3) exact value of PAGE_MARGINS option

Thanks,
Vadim

Hi,


1) Office 2010
2) Yes
3) 2.0cm;2.0cm;2.0cm;2.0cm;

I also tried :

exporter.setParameter(AWExporterParameter.DOCX_COMPATIBILITY, 2010);

with 2007, 2010, 2013 but i always see [Compatibility Mode] on top of Word window, and the export is still the same (bad spacing)

Thanks

Hi Jerome,

I almost done with improving logic for positioning tables.
Seems all works fine except one page only - need to slightly decrease bottom margin.
So is it possible to change bottom margin as follows - “2.0cm;2.0cm;2.0cm;1.5cm;” ?

>but i always see [Compatibility Mode] on top of Word window
Thanks for letting know, we will work on this also.


Thanks,
Vadim

In fact, custumers may customize their templates and customize the margins. So we can’t hard coded margins


Thanks

Hi,


Thanks for the new release 2.7.3 !

The issue seems to be resolved (no NPE, no blank page) when i 'm not using USE_POSITIONING_TABLES parameter.

Indeed, if i use USE_POSITIONING_TABLES with SMART, there’s still have some issues : page breaks, blank pages, bad borders table rendering.

With ALWAYS, it’s worse.

So, i will not use this parameter.

Thank You
