Simple SUM functions not calculating in final spreadsheet

I upgraded to v 1.7.2 from an ancient 1.5.x release version. Suddenly my resulting spreadsheets with simple summation functions show the SUM text and not the result of the execution of the summation.

For example, I now see:

=SUM(G11:G21) in the cell.  If i manually edit the cell and simply hit ENTER on the summation formula, it does the summation.


Any tips to rectify this?

I see that others have had this problem as well (going back a few versions even).  The issue is identical for me -- you must "touch" the cell through either double clicking or editing and hitting enter to activate the execution of the function.

Well, looks like with some brute force, I've figured out what the problem is.

This issue happens when the code I have was setting the cell type to a string using setDataType(PHPExcel_Cell_DataType::TYPE_STRING).

This was done AFTER i already put the cell's value to be the formula shown in the first thread post.

I removed that line and now the summation formula now works properly.  Hopefully this helps others as well.
