Jasper report split type

问题:

I am using jasper report to export my reports to word document. On the detail section I have sub report. I have a problem with band split type. When I choose split type stretch or immediate I got the below problem.

When I choose Prevent split type I don't get this error but this time there are lots of white space at the bottom of page if row space more than remain band height. How can I split my data partially at the bottom of page without border layout error?

sample code. just copy and paste any jasper studio editor and enter long text(at least fill two page) when prompting.

Finally solution solved. Thanks @dada67 for detail answer.

Solution 1: you can create jasperreports.properties file on your classpath and add the below line to this file:

net.sf.jasperreports.consume.space.on.overflow=falsenet.sf.jasperreports.consume.space.on.overflow=false

Solution 2: you can set this value programmatically also

DefaultJasperReportsContext djrc = net.sf.jasperreports.engine.DefaultJasperReportsContext.getI‌​nstance();
djrc.setProperty(net.sf.jaspe‌​rreports.engine.fill‌​.JRFillTextElement.P‌​ROPERTY_CONSUME_SPAC‌​E_ON_OVERFLOW,
                    Boolean.toString(false));

回答1:

The problem you're describing seems to be the same as http://community.jaspersoft.com/ireport-designer/issues/8146

According to the comments, the upcoming release (6.3.1) will fix the issue.

In the meantime you can set the following property in your jasperreports.properties to avoid the problem:

net.sf.jasperreports.consume.space.on.overflow=false
