We are trying to clone a worksheet that has AutoShapes and Pictures in it.
After placing the clone method in the DrawingRecord class, we encountered a
different exception as follows:
java.util.ConcurrentModificationException
at java.util.AbstractList$Itr.checkForComodification
(AbstractList.java:462)
at java.util.AbstractList$Itr.next(AbstractList.java:433)
at org.apache.poi.hssf.record.ObjRecord.clone(ObjRecord.java:182)
at org.apache.poi.hssf.model.Sheet.cloneSheet(Sheet.java(Compiled
Code))
at org.apache.poi.hssf.usermodel.HSSFSheet.cloneSheet
(HSSFSheet.java:114)
at org.apache.poi.hssf.usermodel.HSSFWorkbook.cloneSheet
(HSSFWorkbook.java:337)
After debugging through it, we found out that this error happens in the
ObjectRecord clone method(). We modified the clone method as follows:
public Object clone()
{
ObjRecord rec = new ObjRecord();
rec.subrecords = new ArrayList();
List currObj = this.subrecords;
for ( Iterator iterator = currObj.iterator(); iterator.hasNext(); )
{
rec.subrecords.add(( (Record) iterator.next() ).clone());
}
return rec;
}
After doing this, the worksheet was cloned with the AutoShapes and Pictures
