I think I encountered something strange with the Filemaker Go webviewer on an iPad. I am trying to pull data from my MySQL server using a web viewer. On FM Pro the following worked fine:

Set Web Viewer [Object Name: "WV_Main"; URL: "http://myserveraddress.com/DownloadTables.php?UserName=...&Password=..."]

However on FM Go this did not work. The webviewer showed nothing. When I preceded this script step by two other steps it did work:

Set Web Viewer [Object Name: "WV_Main"; URL: ""]

Pause/Resume Script [Duration (seconds): 1]

Set Web Viewer [Object Name: "WV_Main"; URL: "http://myserveraddress.com/DownloadTables.php?UserName=...&Password=..."]

Removing the pause causes the webviewer to remain empty also. Anybody an idea as to why this works?

Experiencing the same thing here. Haven't been able to find a solution for it but working on it!

1sec seems to be the minimal required duration, which is too bad.

Did you find a workaround already?
