jasperreports plugin's ValueStackDataSource converts field values in ValueStackDataSource even
when it's not wanted
-------------------------------------------------------------------------------------------------------------------
Key: WW-3698
URL: https://issues.apache.org/jira/browse/WW-3698
Project: Struts 2
Issue Type: Bug
Components: Plugin - JasperReports
Affects Versions: 2.2.3.1
Environment: Tomcat 7 application server, Jasperreports 4.1.1
Reporter: Dario Tortola
Priority: Minor
Report A with Subreport B
Subreport B's datasource is a java.util.List field of Report A's datasource's elements
org.apache.struts2.views.jasperreports.ValueStackDataSource.getFieldValue, after locating
the value, if org.apache.struts2.util.MakeIterator.isIterable(value) instead of value a new
ValueStackDataSource over value is returned.
Since ValueStackDataSource is not a java.util.List, a javax.servlet.ServletException is thrown
when the returned ValueStackDataSource fails to be cast to List
To avoid such unwanted conversion it's enough to change this code on ValueStackDataSource.getFieldValue
if (MakeIterator.isIterable(value)) {
return new ValueStackDataSource(this.valueStack, expression);
} else {
return value;
}
replace (MakeIterator.isIterable(value)) with (!field.getValueClass().isInstance(value) &&
MakeIterator.isIterable(value)) for the new ValueStackDataSource to be returned only if the
value is not already what the field asks for
