Hello Tommy,

I am sorry to hear you are experiencing such a behavior. Using the latest version of the framework I was not able to reproduce this behavior on my machine.
If you are not using latest version please proceed with upgrade. If you are using latest version please provide a sample test/project that I can execute and reproduce the behavior.

In this testing project the expected value stays empty in firefox while it works just fine in chrome and IE.

But i dont get the serialization error here.

Hello Tommy,

Thank you for providing me with the project and the sample web page. I would appreciate if you guide me on how to proceed and which test to execute in order to recreate this behavior.

Looking forward to hearing from you.

Run the sample webpage on a webserver. Change the baseurl in the test settings to the url of the sample page.

The test you need to execute is the main test.

Hello Tommy,

Thank you for your explanation. I was able to run the test and invoke the script under Firefox without being able to reproduce this behavior on my end. I am using the latest internal version of Test Studio and the latest Firefox browser.

I solved this by removing the <string> specifier. Thanks for your help anyway.
