Widgetset does not contain implementation

Vaadin 6 / 7 / 8
1

Hello

I have just upgraded the project to use latest vaadin version 6

After changing the vaadin version to 6.8.17 -

I tried recompiling the Widgetset
vaadin:update-widgetset &
gwt:compile

I could see the files generated with the latest timestamp under - the project/…/src/main/webapp/VAADIN/widgetsets

Cleared browser cache,
Restarted the jetty

But when the webpage which uses the widgetset loads, the browser is throwing the error -

Widgetset does not contain implementation XXXXX heck its @ClientWidget mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:
-Unrendered UIDL

Please advise.

Thanks

Did you tried vaadin:compile instead of gwt:compile ?

Usually vaadin maven plugin should have same version as vaadin framework. Try to set version to 6.8.17 and then vaadin:compile again

Vaadin maven plugin does not have version 6.8.17

https://mvnrepository.com/artifact/com.vaadin/vaadin-maven-plugin

Sorry, my mistake. I’ve wrong read 6.8.17 as 7.6.8

Any other suggestions please?

I guess you have already tried to delete the whole src/main/webapp/VAADIN/widgetsets directory.

Do you use some addon from directory that could be incompatible with the new vaadin version?
Does the widgetset compilation give some kind of error or warnings?

Yes, I deleted the whole src/main/webapp/VAADIN/widgetsets directory and compiled- gwt-compile & vaadin:update-widgetset

I had attached gwt-compile console log.

Though the browser shows Widgetset does not contain implementation error…
Widgetset component works fine in the UI…

I am really confused…
I had restarted my machine, browser etc., to clear out any cache issues…

Please help

I’m sorry, I’m not able to reproduce your error.
Have you tried to use version 1.0.2 of vaadin-maven-plugin?
I’ve got dependency errors runnig 1.0.1

The goal vaadin:update-widgetset scan the classpath to find available widgetsets and then updates the .gwt.xml file.
Seems like that your own widgetset is not fount on classpath; according to the log you posted also the MaskedTextField addon seems not to be on classpath.

BTW, if update-widgetset is not configured to automatically run you should invoke it before gwt:compile

mvn clean compile vaadin:update-widgetset gwt:compile package jetty:run HTH

Yes, the two goals will run automatically on the default phase they are bound.

To add addons on classpath simply add they as dependencies in pom file;
for example

<dependencies>
   ...
  <dependency>
      <groupId>org.vaadin.addons</groupId>
      <artifactId>maskedtextfield</artifactId>
      <version>0.1.1</version>
   </dependency>
   ...
</dependencies>

When using addons from vaadin directory also make sure you added the repository configuration

    <repositories>
     ...
      <repository>
        <id>vaadin-addons</id>
        <url>http://maven.vaadin.com/vaadin-addons</url>
      </repository>
      ---
    </repositories>

Can you please post the output of
mvn vaadin:update-widgetset ?

13

So seems like your XXXX addon is not found during scan.
Please, forgive the silly question: is the MANIFEST file of your addon correctly filled with vaadin entries?

Vaadin-Package-Version: 1
Vaadin-Widgetsets: com.package.AddonWidgetset
...

All seem ok, I can’t figure out wath is happening.
Did you tried yo use -X flag when launching vaadin:update-widgetset or gwt:compile? Maybe this can give some additional information

mvn -X vaadin:update-widgetset
