ERXSequence throwing exception

[ijazfx]

I've updated my wonder to latest. The application that was running fine all of a sudden seems to be broken. I'm getting following exception what getting a DatabaseSequence object.

This is the line of the code:

new ERXSequence.DatabaseSequence(editingContext(), "MyModel", "VisaApplicationProcessNumber");

and below is the exception.

Caused by: com.webobjects.foundation.NSForwardException [org.postgresql.util.PSQLException] No results were returned by the query.:Error fetching sequence: VisaApplicationProcessNumber
at er.extensions.eof.ERXSequence$DatabaseSequence.increasedMaxValue(ERXSequence.java:227)
at er.extensions.eof.ERXSequence.nextValue(ERXSequence.java:65)

Caused by: org.postgresql.util.PSQLException: No results were returned by the query.

at er.extensions.eof.ERXSequence$DatabaseSequence.increasedMaxValue(ERXSequence.java:210)

Here is the database query:

qshield=> select * from erx_sequence_table;
name_ | value_
------------------------------+----------
VisaApplicationProcessNumber | 2777

The fix for this is following:

I've debugged ERXSequence.java and found that following statement is causing problem:

168: con.createStatement().executeQuery(updateStatement);

Since updateStatement does not return any result, it throws exception. I changed this with following which fixed the issue:

168: con.createStatement().executeUpdate(updateStatement);
