I got a similar problem but couldn't figure it out: this thing is driving me crazy and i am getting desperate.
Here is the thing: I have developed a quotation model in Excel, with data validation lists, a simple VBA macro and when i think everything's working out, i get a message at the opening of the workbook stating that Excel found some unreadable content and
that it must repair/recover the unreadable content; when i click OK, the workbook opens and a message appears stating that Excel successfully repaired/recovered the file by removing some feature: "Removed Feature: Data validation from /xl/worksheets/sheet6.xml
part". When i open the log file repairs, here is the log:
<?xml version="1.0" encoding="UTF-8" standalone="true"?>
-<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"><logFileName>error064840_02.xml</logFileName><summary>Errors were detected in file 'C:\Users\Admin7\Documents\CommercialLighting\Jobs\Quotation - Park Regis
- 18102012\Quotation_ParkRegis_Hotel - MASTER.xlsx'</summary>-<removedFeatures summary="Following is a list of removed features:"><removedFeature>Removed Feature: Data validation from /xl/worksheets/sheet6.xml part</removedFeature></removedFeatures></recoveryLog>
Bottom line: All the data validation lists get removed from the file and my model no longer is usable.
I have been looking for a solution everywhere and i haven't been able to find any to my problem. I am not sure what's wrong with my model: I thought the original model was corrupted so i created the same model in another workbook but it happened again. I thought
it was the VBA code that screwed everything up (I create a data validation list in one cell, from a string of dynamically generated list of characters, which i thought may get too long. So i created another workbook without the VBA code and the same problem
happened again); sometimes you can create a few data validation lists and the problem doesn't appear, but it seems like if many lists are applied to many cells, then the problem appears.
I have attached to this post a link to my file in dropbox:
If you try to open this file, you'll get the error message, which won't help you out much since if you click "YES", all the data validation lists will be erased. That's why i am attaching another file as well https://dl.dropbox.com/u/29163345/CL_BC_BASIC_UNCORRUPTED_VERSION.xlsm
This file is at a stage where excel doesn't trigger the error that erases all the data validation lists, so you can see where my lists are located (LU_DET_BA tab). You will notice the difference between the 2 files: in the first, there're more columns (and
therefore lists) ... And this is what seems to get excel to trigger this error message: there's a point when you keep adding columns (still in tab LU_DET_BA) where excel will trigger the error and all the data validation lists will be erased.
Not sure if you'd be able to work it out but i'd greatly appreciate if someone could have a look at it.
Anyway, i have no idea of how to work it out and i hope one of you guys may be able to help me out with this; that'd be awesome, you'd be awesome haha
i can send the workbook if you provide me with an address.
