When starting, I get such errors
(TypeError) : Cannot read property ‘parseDate’ of undefined
(TypeError) : $0.setOption is not a function

Are you using Spring / Spring Boot?

Yes

Have you added the FC packages to be scanned to @EnableVaadin?

(please also see “Overview/Build problems…” and documentation of @EnableVaadin annotation for further explanation )

Stefan Uebe:
@EnableVaadin

Adding setting @EnableVaadin does not help

Can you please create an issue in github with your source code?

Hi Stefan can you provide an example how to properly set the @EnableVaddin with its parameters values?

I’m getting this warning deploying the application

and when I try to start it from TOMCAT

There was an exception while trying to navigate to ‘’ with the exception message ‘Error creating bean with name ‘com.mattia.matproject.ui.viewRecord.RecordView’: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.mattia.matproject.ui.viewRecord.RecordView]

tks

Simple question, but when you increase the available memory usable for your Tomcat (-Xmx option), does this issue still occur?

(I’m looking for solutions how to optimize the language / locales package size but cannot guarantee a nearby solution.)

Also please have a look on this issue, maybe it is the same reason: https://github.com/stefanuebe/vaadin_fullcalendar/issues/35
