Manager.ActiveBrowser isn't working

[Artem]

Hi,

We're migrating from WebAii 1.1 to WebAii 2.0 and found some problems.
One of them it's a problem with Manager.ActiveBrowser Property.

When I'm using on of these methods:
            Manager.ActiveBrowser.WaitUntilReady();
            Manager.ActiveBrowser.RefreshDomTree();
I'm receiving an error:
System.NullReferenceException: Object reference not set to an instance of an object.
at ArtOfTest.WebAii.Core.Browser.ExecuteCommandInternal(BrowserCommand request)
ArtOfTest.WebAii.Exceptions.ExecuteCommandException: ExecuteCommand failed!
BrowserCommand (Type:'Information',Info:'IsReady',Action:'NotSet',Target:'null',Data:'',ClientId:'Client_e525dafc-eedf-434b-867a-ce3dadb58785',HasFrames:'False',FramesInfo:'',TargetFrameIndex:'-1',InError:'False',Response:'')
InnerException: System.NullReferenceException: Object reference not set to an instance of an object.

at ArtOfTest.WebAii.Core.Browser.IsReady()
at ArtOfTest.WebAii.Core.Browser.WaitUntilReady()

But when I'm using Manager.Browsers[0]  everything is ok, But unfortunately this workaround require us to do huge amount of work, because we have already created a lot of tests (3000+) which now work using WebAii 1.1

 

 Could you assist us with this issue?

Best regards,

Hello Artem,

This problem sounds very strange and interesting. We took great care that problems like this would not happen when you upgrade the framework. Yes I'd like to study this problem. Can you send me one sample test where you see this problem? Please tell me which line number in your code throws the exception when you run it under 2.0.

Kind regards,

Hi Cody,

Unfortunately we have strong confidential policy so we can't give you access to our application. And on other sites I can't reproduce this issue.
But I think I know where the problem is. In our application we have one dummy pop-up window(to check if pop-up blocker is enabled), which opens right after login to application. So I think that the problem is that Manager.ActiveBrowser sets to this window and after this window is closed. Manager.ActiveBrowser becomes Null.
With WebAii 1.1 Manager.ActiveBrowser was equal to latest opened and not closed browser but now with WebAii 2.0. as I see, Manager.ActiveBrowser is latest opened browser without checking whether it is open or not.
