The calculation chain is not updated after formulas that contain custom functions are removed during the document export

created 9 years ago (modified 9 years ago)

When i save my worksheet with option:

C#
ws.Options.Export.CustomFunctionExportMode = CustomFunctionExportMode.CalculatedValue  
ws.SaveDocument(outputFile, DocumentFormat.Xlsx);

CalcChain in outfile is not updated. All formulas are replaced by values but this cells are still in CalcChain.

For MS Excel this is not problem, but if i load this file with code, i get a nullpointer exception in DevExpress-class:

C#
public class CalculationChainElement  
...  
  private bool CellsChainContainsCell(CellsChain chain, ICell cell) =>  
    ((cell.FormulaInfo.NextCell != null) || object.ReferenceEquals(chain.Footer, cell))

because cell.FormulaInfo is null. Remember, cell-formula was replace by value in step 1.

Is it possible to fix that?

  1. Update CalcChain while saving worksheet with CustomFunctionExportMode.CalculatedValue.
  2. Be more fault-tolerant while loading document.

Thank you for your help,
Sascha
