I have an advance query and then I converted the list to object and assign the value to the dataset parameter of cell_writerange.

The cell_writerange throw this error:
"Unable to cast object of type '#NPb.#MPb[ssERP_EDI_Service.RCEDISalesOrder..."

This is working before is there any new release version of the excel package?

our environment is currently running on 9.1.0.10.

any ideas?

Another bug in the api using the cell_writebyindex.

I iterated to a record list so each iteration I use the cell_WritebyIndex and then increment the row I manually assign the column value by just adding another cell_writebyindex each cell_writebyindex is corresponds to the number of column in my structure. So, if the value is a string I left the cellType to null or "" but when I downloaded the excel the cell is empty. But, If I assign the structure column value to cellType and cellValue the excel cell is not empty anymore. 

Is this a known bug or not?

any ideas?
