Simular to this users experenience but not quite:

When using GridEditUpdateUsingRefreshOption yes, we found it was only working on windows gui against the SF not against IAM. When i added GridEditUpdateUsingRefreshOption to the global runtime configurations in IAM it was working in all of our DTAP enviroments. But when trying to figure out why it works, what overrules what. I tried seeing if an application extended property could overrule the global runtime config, and in doing so, GridEditUpdateUsingRefreshOption stopped working. I tried the task resetting extended properties, deleting GridEditUpdateUsingRefreshOption in the application, and adding it again, i tried deleting and adding GridEditUpdateUsingRefreshOption to the global configuration, i tried closing and reopening my gui after every step. I have tried application pool recycling and restarting indicium. Whatever i tried, in our Acceptance the GridEditUpdateUsingRefreshOption is no longer working. In the windows gui against development or production iam it is still working, i just added GridEditUpdateUsingRefreshOption to global configurations and it was and is still working. Although that does seems kinda buggy that it only works as a global config and not as an extended property for an application (only against SF not IAM). Should i make a ticket of this behaviour, am i doing something wrong? Is there already a ticket about this behaviour?
