TableDecorator created with 1.0 doesn't work properly with 1.1. Properties
defined only it decorator
----------------------------------------------------------------------------------------------------
Key: DISPL-298
URL: http://jira.codehaus.org/browse/DISPL-298
Project: DisplayTag
Type: Bug
Versions: 1.1
Reporter: Frode Halvorsen
I made a TableDecorator to use displaytags on a list of Object[], where I
defined all properties in the customized TableDecorator.
It seem to work fine when displayin on web, with sorting and everything, but
when trying to export to Excel, it throws an exception for propertyNotFound.
the class :
package no.song.polka.web.decorators;
import org.displaytag.decorator.TableDecorator;
import org.apache.log4j.Logger;
import no.song.polka.business.*;
/**

*/
public class ResponsibleProviders extends TableDecorator {
private final Logger log = Logger.getLogger(getClass().getName() + "(" +
System.identityHashCode(this) + ")");
private Object[] getObjects() {
return (Object[]) getCurrentRowObject();
// return (Object[]) ((ArrayList)
getDecoratedObject()).get(getListIndex());
}
public String getFromNumber() {
return ((String) getObjects()[0]).split("-")[0];
}
public String getSeries() {
String series = (String) getObjects()[0];
String numbers[] = series.split("-");
return numbers[0].equals(numbers[1]) ? numbers[0] : series;
}
public String getToNumber() {
String numbers[] = ((String) getObjects()[0]).split("-");
return numbers[0].equals(numbers[1]) ? " " : numbers[1];
}
public String getDsp() {
return "" + (Destination) getObjects()[1];
}
public String getOdsp() {
return "" + (Destination) getObjects()[2];
}
}
....
the usage :
<display:table name="result" htmlId="searchResult" id="row" class="polka"
export="true" requestURI="p_17.spr?reuse=true"
decorator="no.song.polka.web.decorators.ResponsibleProviders">
<display:setProperty name="basic.msg.empty_list_row" value='<tr
class="empty"><td colspan="{0}">Søk på nytt.</td></tr>'/>
<display:setProperty name="export.excel.filename" value="providers.xls"/>
<!--display:column property="fromNumber" title="Telefonnummer" /-->
<!--display:column property="toNumber" title="(serie-slutt)" /-->
<display:column property="series" title="Telefonnummer" sortable="true"/>
<display:column property="dsp" title="Nåværende Tilbyder" />
<display:column property="odsp" title="Opprinnelig tilbyder" />
</display:table>
....
the stacktrace when clicking 'excel' :
Exception: [.LookupUtil] Error looking up property "series" in object type
"[Ljava.lang.Object;". Cause: Unknown property 'series'
