Fields in CSV Reports are truncated since library version 6.4.3

[thomas.aregger]

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>[/code]

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 setJRVerticalFiller(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 [/code]

   

I found the following commit on github which changes the source where the properties are read from: https://github.com/TIBCOSoftware/jasperreports/commit/ab16d66354b890047ebd44defaf24a3859e6433a
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.
