Bug 307321 BIRT Column page breaks do not respect page variables
When using an onPageEnd event to increment a page variable and a column page break on a table the html viewer recognizes the updated variable but if you export it to pdf the variable is not updated for every other page. See attached example.

ILayoutPageHandler pageHandler = context.getLayoutEngine( )
				.getPageHandler( );
		if ( pageHandler != null )
		{
			pageHandler.onPage( pageNumber, context );
		}
	}
	
	public void addTableColumnHint( TableColumnHint hint )
	{
		columnHints.add( hint );
	}
	private void setup( AbstractNode node, boolean isFirst )
	{
		node.setFirst( isFirst );
		if ( currentNode != null )
		{
			node.setParent( currentNode );
			currentNode.addChild( node );
		}
	}
	public boolean isRepeated( )
	{
		return isRepeated;
	}
	public void setRepeated( boolean isRepeated )
	{
		this.isRepeated = isRepeated;
	}
