Hello,

my application is initially tied to a database. I have two sqlarray (master and detail) and in both the data are shown properly.
Then I close the database and open a new one with the same schema but just different data. When I ask for master.Query() the app crash. Refesh() do noting and Update() crash as well.
Is there a way to inform the two sqlarraies that the data are changed and they need to update?

Thanks,
Luigi

I guess it is something else... IMO, the easiest way to debug this is in debugger - let it crash and check (or post here) the stack trace...

Of course you were right!
I am working to replace part of old code with two new beatifull SqlArray that work for free for me. Part of this old code backfired.
Thanks and sorry for the false allarm.
