Metastorm v9.1 - an item with same key has already been added

Paul Lawrence

In v9.1 you can no longer use a column from a business object more than once in the same grid.  If you do you will get the above error and you will need to re-code around this.

The qestion is how often do you need to make exactly the same column twice? Making grid like this you send to client the same data two timex get unneccesery bandwidth. You shold try to build form some other way i think. Could you describe situation where this is required to have the same column twice?

I picked this up on a migrated solution so the original design in v7 was not mine. The migration worked in an earlier version of v9 but broke when upgraded to v9.1
