You have test4 as .Tables, .Alias and as Alias in the UpdateNameList.
Such an approach (for instance when replacing table based acces with dozens of implemented rules and screens) is possible with more "footwork" in the base clases, but not recommended when you are new to CA. for new projects use a special prefix for the cursors, for instance crsTablename or T_ Tablename (for Temp).

>The same class with a table with 5 fields doesn't present the problem.....So the problem is in the number of fields ? What do you think ?

>>There are too many fields. Can you try with just a few fields in CursorSchema and UpdateList?

>>>>By the quick glance it looks like you have multiple aliases in the UpdateNameList. You can not update more than one table a time. Use one primary table for your updates and don't include fields from other tables into update list.
