Is more than one WebViewer working to one layout?
If one of WebViewer is working to one layout, it's by this way.
onLayoutEnter, onPanelSwitch, onObjectEnter (popover)....Go to Object [ Object Name: WebViewer objectName ] step at the script end.
FYI: GitHub - Genecom/FileMakerSampleSolutions > TimestampPicker
Yes. Multiple web viewers on one layout. Each in a separate panel of one slide control.
I will take a look.
Even when Go to Object [ Object Name: WebViewer objectName ] is the last step it will still show the refresh icon sometimes.
