IUpdater throws an exception

[abdelrahmanfathe95]

Hello,

I use IUpdater to track added and modified windows to check some rules aganist them, however when I try to open window family document it gives the "third party updater error" and if I try to enable and disable the updater it throws the following exception.

does any one knows what is happening?

Most likely because the Parameters your checking against aren't "valid" in the Family Editor environment. I typically check doc.IsFamily for most of my updaters because rarely do they like both Project and Family environment.
