I've been tinkering with the Group By feature of the Formatter extension, and I came across something that looks like a bug in the extension. In all of my tests, it is not possible to use the extension to update formatter settings on a repeat region.

I followed the video tutorial on using the Group By formatter on a data source. It worked as expected, just as in the video. This is the line of code for my outer most DIV (the main repeat region which holds the Group By Formatter settings:

<div id="list" data-binding-repeat="{{ReportAllCompletedWO.data.groupBy( &quot;adminUserID&quot; )}}" data-binding-id="list">

When I edit the formatter Group By settings for the repeat region , saving the changes destroys all the repeat region code. After doing this, here's what the same line of code above looks like after I try to make a simple text correction to the Group By formatter setting:

<div id="list" data-binding-repeat="{{data}}" data-binding-id="list">

Not only does it fail in updating the Group By settings, but it also removes all of the repeat region code too! I've tried this a dozen times and it does the same thing every time.

I have already tried deleting the cache file and restarting DW, but this is 100% repeatable for me. Hopefully this is an easy fix...

Hi Steve,
Are you sure you properly select the element(on your page) that you need to edit, before clicking the formatter icon?

Yes, indeed. I tried this many many times.
