Plugin does not create MyUI.groovy at startup

[philippneugebauer]

I was able to fix my first issue with the description in #48.

Unfortunately, although I was following the description at https://vaadin.com/wiki/-/wiki/Main/Vaadin+on+Grails+-+Create+project+in+IntelliJ+IDEA, there wasn't any MyUI.groovy in my Grails project after startup, so that I copied a simple one from a vaadin project and adapted it. Now, it does not show the vaadin design and e.g. buttons do not behave like buttons and are simple labels.

the example code is no longer generated automatically. there is a grails task/script to generate them manually. if there is no styling on your app but it feels like in general it is working, there is a problem with the configured theme. check with a tool like firebug on your client, what is happening and also check the server side logs for errors. if nothing works at all it could be a problem with the communication between client and server, the widgetset, ...

Is there any documentation about this grails task? Can you update your documentation according to the changes?

That's just what I get when I run the command.

I'm using grails 2.4.4 and this plugin in version 7.3.9

you are on windows? you can do what the script does manually by creating a file src/groovy/app/MyUI.groovy with the content from the template https://github.com/ondrej-kvasnovsky/grails-vaadin-plugin/blob/master/grails-vaadin7-plugin/src/samples/_MyUI.template

[philippneugebauer]

Yes, I am using windows

Can you verify the fix with version: compile ":vaadin:7.4.7" please?
