I have but i'm still getting ....
Entity 'mytable' is no longer mapped to a target as target table 'dbo.mytable' was not found in the catalog.
Which makes sense as theres no way for llblgen to know that i've renamed it.
So let me walk through what i did...
1) Have an existing project with 100+ tables and numerious manual relations
2) Gone into MS SQL managment studio and renamed all my tables
3) I've then Opened my llblgen project (Build Nov 15th - Version 3) and right clicked on the SQL server node under "Relationsal Modal Data", and clicked "Refresh Relational Model Data from a Database" , entered the connection setting, clicked next
4) First thihng i notice is all my renamed tables are no longer checked in the "elements to retreive"
5) Click next
6) And then my problem is like above i.e. all my renamed table are lost and all the manual properties / relations lost
Hope this makes sense?
