When using any workflow module which has a list of rules (Barcode Reader, Barcode Writer, Zone OCR, ICR, OMR, MICR, Smart OCR, Image Processing, Report Generator) the list of rules will appear totally blank except for the list header, although rules are inserted, saved and fully functional. However the issue will prevent further configuration of each single rule. Existing saved configurations will not be affected and will not brake due to missing display table.
Since the issue might be a show stopper for an advanced configuration a quick patch has been created to fix the issue. The patch is available via automatic updates and marked as KB000039.
The patch is distributed with a self executable installer to run after it has been downloaded. Since the fix involves a JS library a refresh of the browser cache might be required otherwise the browser could still load the old cached library and still produce the issue.
