Length of Uniqueid for matrix Column

There appears to be an inconsistency in the length of the UniqueID that can be used for a matrix column.

For an Addon in 2005 I have UDFs whose name is 12 characters long (including the U_), when appearing in matrix on a system form the system uses the UDF name for the columnID.

However if I try to do the same thing when adding a column to a matrix on a user form I get error -7013 'The string value entered is too long; it should be less than 10 characters [66000-14]'.

Mirroring the UDF name as the column Id allows me to have generic code with out the need to jump through hoops to aling columns and field names.

Is this a known issue for which there is a fix available?

    Hi Graham,

    It's a known issue but I'm not sure if a fix will be provided (it's a 'by design' feature and not a bug). I tested this in SBO 2007A and you still cannot have a matrix column in a user-defined form with a unique id of more than 10 chars.

    Unfortunately, you'll need to code a workaround or reduce your UDF sizes to 10 characters.

    Also, if you haven't already done so, I'd recommend you create a suggestion on the development collaboration forum:

    Kind Regards,
