Vaadin fail to load Failed to load the widgetset

Question

I have changed from vaadin 7.7.12 to 7.7.24, on IBM websphere 8.5; I've compiled the widgetset with vaadin plugin 7.7.24; I install the ear on IBM Was; The compilation give me no problem and I can istall the ear correctely on IBM WAS; But when I try to load the page a pop up tell me:

Failed to load the widgetset: /wps/TEM_COMP_STACO/themes/TEM_COMP/VAADIN/widgetsets/AppWidgetset/AppWidgetset.nocache.js?1642423338694

I've checked that on the server side there is a file called AppWidgetset.nocache.js, but for some reason it cannot be loaded on the page;

Trying more than on time, and the number at the end change 1642423338694, I cannot figure out what that number means;

I cannot change to any vaadin version greater than 7.x.x; I cannot figure out where is the issue. any help is appreciated. Francesco
