Hi,
We have a CSV report where we set the property „net.sf.jasperreports.print.keep.full.text” to true, but since library version 6.4.3 none of the set properties are taken into account anymore.
The result is that now some fields are truncated. As a workaround we increased the width of the fields (<reportElement>).
The jrxml looks something like this:
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="reportName" pageWidth="3300" pageHeight="602" orientation="Landscape" whenNoDataType="AllSectionsNoDetail" columnWidth="3300" leftMargin="0" rightMargin="0" topMargin="0" bottomMargin="0" isIgnorePagination="true" uuid="14c3bf30-038f-4fab-8d41-b9a696b37cc3"> <property name="ireport.zoom" value="1.0"/> <property name="ireport.x" value="0"/> <property name="ireport.y" value="0"/> <property name="net.sf.jasperreports.export.csv.field.delimiter" value=";"/> <property name="net.sf.jasperreports.print.keep.full.text" value="true"/> <property name="com.jaspersoft.studio.data.sql.tables" value=""/> ... ... </jasperReport>
I debugged the report generation (version 6.4.3) and saw that on line 140 of net.sf.jasperreports.engine.fill.JRFillTextElement.JRFillTextElement it tries to read the said property from the main data set of the filler which is null at that point.
I had a look at the stack and saw that it is actually just in the process of building this main data set when trying to read properties from it.
Here is the stack:
JRFillStaticText(JRFillTextElement).<init>(JRBaseFiller, JRTextElement, JRFillObjectFactory) line: 140 <-- Here the instance variable mainDataset of the filler is read JRFillStaticText.<init>(JRBaseFiller, JRStaticText, JRFillObjectFactory) line: 49 JRFillObjectFactory.visitStaticText(JRStaticText) line: 650 JRBaseStaticText.visit(JRVisitor) line: 86 JRFillObjectFactory(JRAbstractObjectFactory).getVisitResult(JRVisitable) line: 88 JRFillBand(JRFillElementGroup).<init>(JRElementGroup, JRFillObjectFactory) line: 82 JRFillBand(JRFillElementContainer).<init>(JRBaseFiller, JRElementGroup, JRFillObjectFactory) line: 95 JRFillBand.<init>(JRBaseFiller, JRBand, JRFillObjectFactory) line: 121 JRFillObjectFactory.getBand(JRBand) line: 524 JRFillSection.<init>(JRBaseFiller, JRSection, JRFillObjectFactory) line: 74 JRFillObjectFactory.getSection(JRSection) line: 500 JRFillGroup.<init>(JRGroup, JRFillObjectFactory) line: 86 JRFillObjectFactory.getGroup(JRGroup) line: 476 JRFillVariable.<init>(JRVariable, JRFillObjectFactory) line: 83 JRFillObjectFactory.getVariable(JRVariable) line: 456 JRFillDataset.addVariable(JRVariable, List<JRFillVariable>, JRFillObjectFactory) line: 362 JRFillDataset.setVariables(JRDataset, JRFillObjectFactory) line: 352 JRFillDataset.<init>(BaseReportFiller, JRDataset, JRFillObjectFactory) line: 297 JRFillObjectFactory.getDataset(JRDataset) line: 1341 JRVerticalFiller(BaseReportFiller).<init>(JasperReportsContext, JasperReport, FillerParent) line: 166 <-- Here the instance variable mainDataset of the filler is set JRVerticalFiller(JRBaseFiller).<init>(JasperReportsContext, JasperReport, BandReportFillerParent) line: 266 JRVerticalFiller.<init>(JasperReportsContext, JasperReport, BandReportFillerParent) line: 69 JRVerticalFiller.<init>(JasperReportsContext, JasperReport) line: 57 JRFiller.createBandReportFiller(JasperReportsContext, JasperReport) line: 219 JRFiller.createReportFiller(JasperReportsContext, JasperReport) line: 234 JRFiller.fill(JasperReportsContext, JasperReport, Map<String,Object>) line: 178 JasperFillManager.fill(JasperReport, Map<String,Object>) line: 474
I found the following commit on github which changes the source where the properties are read from: https://github.com/TIBCOSoftware/jasperreports/commit/ab16d66354b890047e...
In my opinion this commit breaks our reports and I don't understand how this mainDataset can ever be non-null after this change. But maybe someone can enlighten me and tell me what we need to do different so it's not null?
Thanks for your help.

Thomas
