Alert Handling - Selenium WebDriver/ Selenium RC 2.18.0 - Exception

Question

My automation test software for a web application runs on IE, Firefox, Chrome and Safari, and is written using C# and Selenium WebDriver (IE, Firefox, Chrome), Selenium RC (Safari).

A new error occurred when I upgraded to version 2.18.0 today. I am seeing the following exception:

System.InvalidOperationException: Modal dialog present (UnexpectedAlertOpen)

I saw this exception beingn thrown for IE, Firefox and Safari so far.

I looked up the release documentation and did not find anything that suggests that I should do differently to accept or cancel on alerts.

Is this a bug, or is there a new procedure to follow pertaining to alerts?

Answer 1

I had the same problem on my ccnet build server with Firefox since last update and I found that I need a update of my java version because of a security issue.

After the update all my test succeed and I had no more this error "System.InvalidOperationException: Modal dialog present (UnexpectedAlertOpen)".
