SemanticError: The copy operation on the column is forbidden

Tr1aL

Hello, I need help!
(BIRT version 2.3.0)
This is a part of my script:


ReportDesignHandle report = (ReportDesignHandle) session.openDesign(sco.getRealPath("/html/reports") +"/"+ reportName);
TableHandle table = (TableHandle)report.getElementByID(4);
SlotHandle columns = table.getColumns();
ColumnBandData column = table.copyColumn(1);
table.insertAndPasteColumn(column, 1);


Table with ID=4 is exist, also in "SlotHandle columns" I have two column. But when I execute table.copyColumn(1); I have Error:


org.eclipse.birt.report.model.api.elements.SemanticError: The copy operation on the column "1" of the element "{1}" is forbidden.
at org.eclipse.birt.report.model.api.ColumnBandCopyAction.copyColumnBand(ColumnBandCopyAction.java:74)
at org.eclipse.birt.report.model.api.TableHandle.copyColumn(TableHandle.java:339)



Also table.canCopyColumn(1); return me false

What I can do to fix this problem? Maybe I must add any property?
Please help me.

This problem it is very actual for me.
There are any variants of the decision?
Maybe I have placed it not in that forum?
