*aspose version : 4.8
*problem : cell c30 in attached workbook is incorrect, it should be updated to b30, but it keep the previous value
*I've save the template just after wbk.calculateFormula with ReCalcOnOpen=false
so it shows that aspose.cells didn't update the value of cell c30 with that of b30
*i know there is a custom function in my workbook
please, just use a dummy ICustom wich return 1, the problem should still be there
