[oXygen-user] Debugger stops showing parameters for a while?

Oxygen XML Editor Support support at oxygenxml.com

Dear Lars,

At some point we added support for allowing the debugger to step also 
inside XPath expressions. This is what happens in your case and the 
evaluation context is changed, that is why those variables are not 
visible at that moment. You can turn that off from
Options -> Preferences --  XML / XSLT-FO-XQuery / XSLT / Saxon / 
Saxon-HE/PE/EE by disabling the "Debugger trace into XPath expressions 
(applies to debugging sessions)" option.

Best Regards,
George Cristian Bina
