Hello! A few minutes ago I was bindind some components when I got an error. I tried to restart Ignition and now I recieve this: [code]Exception: Error running query: Function binding query [Alert History]@5000ms On: Historico.Root Container.Table.data caused by GatewayException: com.inductiveautomation.ignition.client.gateway\_interface.GatewayException: No session found. You must re-login. (message type=199, func=Alert.queryHistory) caused by BindingException: com.inductiveautomation.ignition.client.gateway\_interface.GatewayException: No session found.

(message type=199, func=Alert.queryHistory) Ignition v7.3.2 (b533) Java: Sun Microsystems Inc. 1.6.0\_29 [/code] Can somebody tell me how i can fix this problem? Thanks! ---

Have you tried restarting again? Does it happen every time you open a designer? ---

Well, I see you are using Java 6 Update 29. There are some problems with that version of Java (first one we have run across). Maybe you should try downgrading on the client machine to Java 6 Update 27. See if that fixes the issue. ---

Update 30 fixed the main problem with SQLServer. Maybe it fixed this one too? ---

I don’t think that the problem in this thread has anything to do with Java 6u29. That said, I don’t understand exactly what’s going on here. Is this in the client? designer? what’s being restarted? ---

I solved the problem restarting the client. Apparently it’s a Java problem ---
