Bug 123722 Java based scripting -> getExpressionValue(int i) of IRowData returns unreasonable value
public void onPrepare( IRow row, IReportContext reportContext ) { try { row.setBookmark( "\"row-bookmark\"" ); System.out.println( row.getBookmark( ) ); } catch ( Exception e ) { e.printStackTrace( ); } } public void onCreate(IRowInstance rowInstance, IReportContext reportContext) { try { IRowData rowData = rowInstance.getRowData( ); Object int2 = rowData.getExpressionValue( 1 ); System.out.println( int2 ); } catch ( Exception e ) { e.printStackTrace( ); } } Consider the script above, according to Javadoc, rowData.getExpressionValue( 1 ) will return the first data expr. of the row, i.e. the value of the first column. However, it was noticed that "row-bookmark" was returned instead. And if i used rowData.getExpressionValue( 2 ), then i got the right value. So if it was the correct implementation, it should be clearly stated in Javadoc.

	 * execute the row. The execution process is:
	 * <li> create a row content
	 * <li> push it into the context
	 * <li> intialize the content.
	 * <li> process bookmark, action, style and visibility
	 * <li> call onCreate if necessary
	 * <li> call emitter to start the row
	 * <li> for each cell, execute the cell
	 * <li> call emitter to close the row
