I've run into this issue a few times now. Whenever I click an element within Internet Explorer after it has been launched via a Launch stage, subsequent navigation attempts fail with the error:
Internal : Failed to perform step 1 in Navigate Stage 'Navigate' on page 'Test' - Object reference not set to an instance of an object.
I am attempting to build a process for a website that requires a login. The login page cannot be manipulated via the HTML spying in Application Modeler, so I am using surface automation instead which involves a global mouse click on the Internet Explorer window. After clicking the appropriate button to log in, any subsequent attempts to use a Navigate stage results in the object reference error above.
Everything other than a Navigate command works fine; it is, for example, able to Terminate without an errors when it is in this state. I can perform any number of Navigate stages just fine, right up until the point that a global mouse click is used against the page.
Has anyone else encountered this, or have any idea what would cause this behavior to happen?
