This is very strange. One (only one) of my new clients in Oregon is receiving the following error message after they log into the WebDirect application using Chrome or Firefox browsers. Externally hosted FMS 13. They are within a government network. They are going to try it from home. Hundreds of other clients are able to login with no issues. I saw some references to this error on this community, but no solutions. Any ideas?

Check its component connector’s @Connect mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. "
