Documentation:Unknown valuetype

There is an error of unknown origin that may destroy the model info needed for Evolve of the Admin db of MDrivenServer.

The error shows up as:

Problem in portalpush Unknown valuetype in admin_ECO_ORMAPPING table ()

The root cause is yet unknown. The admin_ECO_ORMAPPING has been wrongfully cleared of model info.

To fix - find other MDrivenServer with same current admin model and go to <mdrivenServer>/admin/EvolveDebugPage.aspx

Execute the "Get from Current"

Copy the resulting xml text from the Admin DB Script box

Paste this value into the MDrivenServer with the error - Submit - then "Update Current With Given"

(this operation insets the missing DB Script. There are other ways to do this - download db - use SqlCompact tool like LinqPad - insert missing script. Upload model)
