***Note from Migration:***

Original Title was: ChangeDetector - pass attribute from original features to updated features when not one of the selected attributes


@ebygomm asked this question. I ran into the same issue, so it might be helpful to other people as well. With this idea, it might be caught by Safe's radar.


In the change detector is there any way of transferring an attribute value from the original feature to the updated feature when it's not either a Key Attribute or one of the attributes listed in the matching strategy

e.g.

 

Like @mark2atsafe mentions in his answer, it is very weird. You would expect a Merge Attributes section, like on other transformers.


Current workaround: follow up with a FeatureMerger/Joiner transformer to copy info across.

Yep!!! This is a must have in my opinion, the lack of this attribute passing makes what should be a very clean change detection solution into a bit of a messy workaround.
