Description Kevin LaVergne 2004-11-02 22:30:42 UTC
When attempting to clone a sheet that had an image on it, I got an Exception 
saying that DrawingRecord must implement a clone() method.  I added this clone() 
method and the image was copied onto the cloned sheets without any problems.

public Object clone()
    DrawingRecord rec = new DrawingRecord();
    rec.recordData = recordData;
    return rec;

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:

	at java.util.AbstractList$Itr.checkForComodification
	at java.util.AbstractList$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 
	at org.apache.poi.hssf.usermodel.HSSFSheet.cloneSheet
	at org.apache.poi.hssf.usermodel.HSSFWorkbook.cloneSheet

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
