I've met a weird problem.
I'd create a business object extension and a script with AfterModify Event on that.
And both were activated, but if I click on business object extension in solution explorer, it becomes unactivated, even nothing changed.
Then I can't activate it anymore. It shows error message like this.
If I delete the script item below the extension, it could be activated again.
So I guess, if I want the extension be activated, I must not have any script item under it.
Does anyone have any suggestion?
