問題

When trying to delete an application link, the delete dialog appears with a stack trace. The "Confirm" button is disabled and "greyed out".

原因

When you are trying to delete an application link, the application tries to connect to the remote application as well. When an error appear such as connection or authentication errors, the Confirm button remains disabled.

ソリューション

In Google Chrome:

1. Right Click on the "Confirm" button
2. Inspect Element
3. In the HTML, remove the disabled="true" parameter for the button object
4. Click on confirm
