[Spring vaadin]Communication problem without no errors in console.

Hi, This is my first time to post to forum.
As title describes, I have an error without console error message.

I have some experience with Spring framework, but new in Vaadin.

Since I want to use minimal library dependencies,
I made my project with Eclipse(Luna) ‘Dynamic Web Project’ and ‘Convert as Maven Project’.

This is my project link. Would you like to check this out?

For people who do not want to visit github, following is summary of what I have done.

  1. Built a Dynamic Web Project in eclipse Luna
  2. Convert this project as Maven project
  3. Add followings to pom.xml. Spring web mvc (4.1.7 RELEASE) / Vaadin-client-compiled / Vaadin themes (7.5.1) / Vaadin-Spring (1.0.0.beta3) / add repository : vaadin-addons
  4. Implemented a Class which implements WebApplicationInitializer (Since I do not want to use xml settings)
  5. Made config Classes(RootConfiguration / ServletConfiguration)
  6. Made a Controller bean (just for url redirecting)
  7. Made a VaadinUI Class wich @SpringUI annotation

When I ran this Web Application, I can see button UI.
However when I click, it stops without any error messages on console.

Looks like widget set problem.
I can see an error message in browser console, not eclipse.
It says that …
'your widget set seems to be built with a different version than the one used on server. Unexpected behavior may occur. ’

So how can I fix this?
I want to build a project in eclipse in following condition

  • do not wan to use plugins like STS or Vaadin-plugin
  • want to import libraries which is necessary to execute “HelloWorld”
  • want to use Sevlet 3.0 based settings (Want to reduce xml settings as much as possible)

Sorry for many conditions, but this is what I wan to build :smiley:

This is quite depressing that no one in two months has posted an answer. I am stuck with it my self!

Really want a good thorough guide on how to set up vaadin with spring 4 without a single line of xml. I hate xml!
Most tutorials are lacking…

Indeed. I am really passionated with Vaadin, but my region Spring framework(with MyBatis, Maven) is main stream.(I guess in Java, it took almost 90% over) If Vaadin can not be compatible with Spring, It never be a useful in this region. so shame… :confused:
