Screen collapse


I have a problem with my application. When I open a screen It often collapses, the components are layered above each other. On a custom screen usually a refresh fixes it, but for example the new Report screen looks like:

As you can see there are a lot of errors on the browsers console.
On Mozilla the errors are:

Thu Jan 11 11:16:37 GMT+100 2018 com.vaadin.client.ApplicationConnection
SEVERE: Warning: your widget set seems to be built with a different version than the one used on server. Unexpected behavior may occur.
Thu Jan 11 11:16:51 GMT+100 2018 com.vaadin.client.communication.MessageHandler
SEVERE: Error handling type data (TypeError) : $wnd.jQuery is not a function

And here is an example of a custom screen where the third button (Fileupload button) won’t show:

Do you have any solution for this?
Thanks in advance,

Hello Julia,

Please clarify what version of CUBA do you use?


Hi Daniil,

I’ve just updated my Cuba Studio version so it’s 6.7.6.
The project platform version is platform-6.7.2.

Thanks for the help,

It’s strange. I’ve created a test project and everything is ok:

Do you have a web-toolkit module in your project? It seems that you have problems with a widgetset.

Also, try to rebuild and restart a project with the following command:
gradle clean dropTomcat setupTomcat deploy start.

It would be nice if you share a demo project where the problem can be reproduced.


Hi Daniil,

I have run the gradlew clean dropTomcat setupTomcat deploy start command and it fixed it!

Thank you!
