Template Change Does Not Update Elements

I've implemented a custom data reference and used it in an AF Element Template so that it will be propagated through the AF database. Initially, I create, configure, and check-in the data reference for the element template and the elements in the AF database that inherit that template are successfully changed. However, when I go back to the element template, update my configuration and checkin, the elements that were originally created from the template are not changed. I've seen the elements that implement other templates update automatically before, so I'm a bit confused why I'm not seeing this behavior now. Probably a silly misunderstanding on my part. Anyone have any ideas? Thanks in advance for any comments.

What happens if you right-click on the element instance and select "Reset to Template"?

Steve,

That properly updates the element. Thanks for the help. I had assumed the elements would automatically update so I thought there might be a DataReference method that I did not properly override. After looking over the System Explorer User Guide I have a better understanding. Thanks again.

Hello Cory,

Remember that there is a method called ResetToTemplate() in PI AF SDK that performs the same task that Steve has suggested. Therefore, you can easily create a custom application that would reset to templates all the elements derived from an specific elemente template. Please refer to this thread.

Hope this helps!!
