Update Period Error in v1.9

---

I upgraded to 1.9 and wanted to change the update period on the modbus data source. I get a dialog box that says error and no description.

Used to work in v1.8.

Try pressing ctrl+f5 in case there is old code in your browser cache.

Ctrl-F5, Clear recent history (Firefox), tried in in IE, restarted mango, still the same dialog.

Can't recreate. Is there any message in the Tomcat console? And is it serial or IP?

Serial.

Still works for me. Can you send the editModbusSerial.jsp file and confirm that in system settings it says 1.9.0?

System setting = 1.9

See attached file for JSP.

Still all good. Can you shut down Tomcat, delete the contents of its "work" directory, and then restart? A JSP may not be getting recompiled.

That did it. Left overs from something.

thx
