ERD-enabled display giving "Unable to locate data point" message for non-existing attributes

We have a set of ERD-enabled ProcessBook displays which our client has been using for a year now.


The AF elements are inheriting from a template called "Circuit breakers". Appr. 10% of the breakers inherit from a template called "DGA Circuit breakers", which then is derived from the main circuit breaker template. It has some extra attributes for gas analysis.




We've been using ProcessBook together with AF 2010 R3 I think ( until we recently upgraded to AF 2012. I don't know if my problem came about before or after that, but I do know that we didn't have the problems before.


The problem comes when navigating between a DGA-enabled breaker and a normal breaker, but it only appears some of the times. Where I previously just got "NO DATA" displayed I now get popup messages for each and every one of the data points missing, resulting in many extra clicks for the users. The message is "Unable to locate data point" plus a reference to the attribute it's looking for (which obviously isn't there).


But the strange thing is that I don't always get the message. Sometimes I just get the message for one or two of the missing data points, other times I get it for all of them. I would like to find out what is causing this error message, and why ProcessBook determines that some of the missing data points are important enough to give a popup message warning instead of just printing out "NO DATA".




Any ideas?
