Here is an update again… Well, that should be the last one as the tool should manage every aspect of a view layout from now.
So, the problem was the following: When views were replicated, some attributes that are not used in the layout were remaining in the fetchXml part of the view (the part that defines which records will be displayed).
This avoids to delete these attributes from the entity as they were still used in a published view, even if you were not able to remove this reference (Unless you export the customization, remove the attribute from the fetchXml and import back the updated customization).
This new version takes care of the layoutXml (which columns are displayed) AND the fetchXml (which attributes are retrieved under which conditions).
I hope nobody was affected by this problem.
As usual, you can download the latest version on the right pane of this blog.
