In reviewing the A5XBasicErrorStackLog.txt from a production AA IIS server under build 5303, I see the following repeating error:

Wed Jan  2 10:19:46 2019 Extra characters at end of expression
Execution Stack:
0#666 a5w_report_saveAs(reportName,saveAs,filter,order,filename,global_variables(),printOptions,args,options)
This error happens when someone (me in the above example) saves a LayoutTable report as PDF, even though the operation is successful and the PDF is shown on-screen.

Is there an AA IIS build after 5303 that does not generate this error in the xbasic error log and that is okay to put into production environment?
