DA View "Forgets" About Monitored Items

[osteste]

Hi,
I'm Using UA Expert V 1.3.1 206.
I have two different servers.

I connect to both of them and drag&drop some variables with changing values into the Default DA View.
Then I save the project. And reopen it again. The Servers are still running.
When reopening, only the monitored items from one of the servers are still in the DA-View; The monitored items of the other one disappeared (Not grayed out or not changing, but completely gone).

What can be the reason for this behavior? What triggers the UA-Expert to remove the monitored Items from the DA-View or to not load them from a saved project?

[Support Team]

Hi osteste,

please have a look at the Log Window of UaExpert if there are hints about the removal of the monitored items. A namespace change can lead to this behaviour but will issue appropriate traces in the Log Window.

Best Regards

I reproduced the Problem, the Log is attached.

11:45:22.638 | Server Node | AGS | Namespace table changed, mapping old to new namespace indices

What happens here? The Namespace array didn't change, but somehow the UA Expert believes in it and maps old NS3 to NS11.

How does the UA-Expert validate the Namespaces? How does it "Map" the old to new ones?

[edit] According to a co-worker it is easily reproducable with all kinds of servers with more than 10 Namespaces. [/edit]
