version: Studio Pro 2016.2.6344
when running the assignment 1 workflow, came into an fatal exception as below picture shows
in the activity “Open application ‘UIDemo.exe UiDemo’”,if I put “in_Config(“UiDemoPath”).ToString” into the property FileName, then the exception came out
then i print the “in_Config(“UiDemoPath”).ToString” into log and put the print result into property FileName of Activity “Open application ‘UIDemo.exe UiDemo’”, the workflow can run as expectation
any expert knows why???
thanks
