Another extrange behaviour I noted is in T3. 1) I defined a table and I inserted a value in a int record.
2) I noted I was worng with the type field, I wanted a string, so I deleted the record and redefined type field in define_table 3) I changed the type of record from int to string, web2py respoonded me OK 4) reallyr web2py doesn't changes type field, but models has type string at define_table I had to use SqliteManager to change table.
