Webinar: Vaadin 7.7 - using the new AppWidgetset and CDN

Largest enhancements in Vaadin 7.7 are related to the handling of your application Widgetset. Widgetsets in Vaadin are GWT modules which combine client side component implementations from the core and from various add-ons to a compact client side engine needed by your application. Since 7.7, widgetset handling became much easier for newcomers and there is also a cloud service that makes working with add-ons much faster. Join the webinar hosted by Matti Tahvonen and Teemu Suo-Anttila to learn how to work with these enhancements.

Webinar takes place on Thursday September 1, 2016 @ 2PM CEST

See https://vaadin.com/webinars for other past and upcoming webinars.

You can post your questions below, thank you!

sound is very low !! maybe is me !!

The sound volume is very low for me also, I can barely hear you guys with everything maxed out.

Lino Costa: sound is very low !! maybe is me !!

No, you are right

no sound !
 

We can't hear anything! Please fix sound.

Please volume up, hard to listening 

yes a little better

can be ok, even is not perfect

ha now is good

thank you

Is there a possibility to have the vaadin default widgetset get from cdn and my own widgset from local (in .war), or better, define per widget where is located?
 

Edison, that is not how GWT is designed, so the answer is no. GWT does all it can to combine and optimized a monolithic JS engine for the end users. Thus it needs a full compilation with all the modules and in that it combines just on junk of JS. This way the JS engine is faster and more compact.

cheers,
matti

PS. Sorry for the nasty sound issues, somebody had touched our mixer during summer vacation ;-) We did a re-recording right aways.

Do I need to change some code in my pom.xml with Vaadin 7.7?
I get the following error when I do a "clean package"

Could not find or load main class com.vaadin.server.widgetsetutils.WidgetSetBuilder

I also have a red label in my pom.xml after switching to vaadin 7.7

Failed to update widgetset (com.vaadin:vaadin-maven-plugin:7.7.0:update-widgetset:default:generate-resources)

If I switch back to vaadin 7.6.8, everything compiles correctly.

Here is my pom.xml from my widgetset module

Hi jcfortier,

Try specifying the version for vaadin-maven-plugin. Also you should be able to get rid of most configurations now, there are much better defaults now. Try with this:

<plugin>
                <groupId>com.vaadin</groupId>
                <artifactId>vaadin-maven-plugin</artifactId>
                <version>7.7.0</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>compile</goal>
                            <!-- Comment out compile-theme goal to use on-the-fly theme compilation -->
                            <goal>compile-theme</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

cheers,

Thanks!

I'm trying with a new project from maven archetype, set "cdn" instead of "local" for widgetset mode and added Vaadin Charts dependence. But when I build the project I get an error with my Charts CVAL license (perpetual license​, no subscription):

[ERROR] Failed to execute goal com.vaadin:vaadin-maven-plugin:7.7.0:update-widgetset (default) on project vaadin-app: Cval license check failed! Vaadin Charts 3 registered to xxxxxxxxx@xxxxxxx.xxx -> [Help 1]

​With "local" mode everything goes right. Are perpetual licenses supported in CDN mode?

Perpetual licences should work just fine as well. If it don't it is bug. I'll ask our engineering to see what is going on.

cheers,
matti
 

Ok, thank you!

​Let me know if I need to open a bug report or something else.

Can anyone help me on the ContextMenu?
Or does the 7.7.0 really works the way it says?

Matti Tahvonen: Perpetual licences should work just fine as well. If it don't it is bug. I'll ask our engineering to see what is going on.

cheers,
matti

 

Hello Matti, do you have any update about this?

Henri Sara: Created ticket and fixed the perpetual license issue in http://dev.vaadin.com/ticket/20287 - the fix will be included in 7.7.2.

Thank you very much! I look forward for the release!

Hi,

My project was running fine using Vaadin 7.6.8, but when moving to release 7.7.1 I got this exception:

​Exception in thread "main" java.lang.IllegalArgumentException: URI has an authority component
[ERROR]     at java.io.File.<init>(File.java:423)
[ERROR]     at com.vaadin.server.widgetsetutils.WidgetSetBuilder.updateWidgetSet(WidgetSetBuilder.java:74)

Any hint please ??

Hi,

That's a known issue in 7.7.1. You'll need to roll back to 7.7.0 or wait for the fix that comes with 7.7.2.

-Olli

Does it really work?
I'm always getting "SEVERE: Failed to connect service https://wsc.vaadin.com/api/compiler/compile"
 

It does, I trust it more than our liferay based website :-)

Let's try to find the issue you have! Could you share the project you are using or the full maven log?

cheers,
matti

Full maven log (can't attach a file and debug mode is 500ko...).
It compiles well in "local" mode.

I created a really simple project with the add-ons you used and I can now reproduce the issue. lazylayouts and vaadin-autocomplete add-on seems to both break the build somehow. I'll create an issue about it!

Thanks!
 

The application has an Appwidgetset.gwt.xml which contains references to all .gwt.xml of whatever add-ons we have in our project which they only contain reference to :

<module>
    <inherits name="com.vaadin.DefaultWidgetSet" />
</module>

If I compile the widgetset from the eclipse plug-in it asks me to select the main xml file (which is the Appwidgetset.gwt.xml) and it compiles everything just fine.

Doing it this way all xml files remain unmodified.

However if I ran from command line in the application project folder

mvn vaadin:update-widgetset install

then it fills all xml files with references to all other xml files. Which behavior is the correct one? What should the xml files contain?

Ok, Thanks! Looks like it is not the connection, but there really is somekind of server-side error (code 500) related to this one. I'll need to ask further.

any progress?
