Since i have started my solution. I am always taking a backup before changing something. This habbit saved me.
I think the problem was repository. repository version was conficting. i had two versions first one which was ok and was showing into smart client open solution list and other new version, not showing into smart client. what i did delete all the tables and servoy repository. then import working version then import other version. while importing a dialogs which asks merging or do not merging. i was selected merge, current version. what ever the confilict was removed then it works.
