Hi again,

I 've been testing my web-apps using a cvs-built version of JBird(just after rc1a).

Today, I tried rc2. When it tries to execute a certain SELECT query that worked before,

I get the following stack trace(as you can see I am using a JBuilder API,

I don't know if there is a relation):

org.firebirdsql.gds.GDSException: invalid request BLR at offset 1786

Note that the query joins two tables one of which has many fields (and blobs) if that matters. I realized though that the number of rows is irrelevant.

Note also that other queries work fine.

I don't know if all the above can help the list, I hope that someone can locate the problem.

Thanx,

Haris.
