j_id0:frm:pageBlock:lotno: Validation Error: Value is not valid
j_id0:frm:pageBlock:exhibition: Validation Error: Value is not valid
j_id0:frm:pageBlock:ItemNo: Validation Error: Value is not valid

Answer 1

Normally this error is thrown when a picklist value is being submitted to the server and there's no matching entry for the given picklist value in the server at the submitting time.

Two possibilities that I can think of:

1. Since you are using sets, which are unordered collections, the order might have been changed at the time of submitting data to the server which can be raised the validation error.

2. In your strings used as SelectOptions keys, there can be strings which include multiple consecutive spaces which can be raised the validation error.

Check for these possibilities. The reason for second possibility is because even in your list it's having multiple spaced string, when it renders it binds with single space. When the data submitted back, it will cross check with the list again and values do not get matched.
