On tag export, delete and import, the tag layout changes coming from the OPC server. For example, lets say I have a tag as:  
[SFDemo]Global.PT100.EU

Sometimes, at random, the tags need to be mapped as

[SFDemo]Global.PT100.PT100.EU

Where PT100.EU shows up as the tag name, not folder \> folder \> EU.

I get a ton of the following error.

OK, on reboot, the tags were fine, except for a few. Every reboot, the same tags are wrong. But I dont think they were wrong during the export delete import error phase.

I see lots of these errors in the console, but for different tags.

[code]Message [SFDemo] Could not find parent while processing tag attribute for PID\_CONTROLLERS.BNOT\_01.

Could you send me your log file again? I’m not really sure how you’re getting this to happen.
