Notes from the Yellow Side

 I've just spent a few stressful hours trying to figure out how to stop getting the following XPage error :-

"Document has been modified or corrupted since signed (data)"

I backed out the changes I had made this morning - no change.
I started taking out Custom Controls until the error stopped, then started reinserting them, which narrowed it down to a few CCs.
I started removing code from each CC until there was nothing left.
I started creating new CCs and adding in chunks of code, but that got too painful trying to rebuild the Property Definitions, Data Sources etc etc.
I gave up with the code and copied the database - no change.
I Compacted the database - no change.
I Fixup'ed the database - no change.
I Signed the database - It works again!

Make sure you detick the "Update existing signatures only (faster)" option just in case it causes it to miss the one it needs to fix the problem...
