Vaadin is a Java framework for building modern web applications that look great, perform well and make you and your users happy.

and you can rule out, that _materialList holds all elements right before setItems?

or rather make sure

Sure, it contains them all

@TatuLund

I do not know details of this component well as it is not made by Vaadin. But if it follows the same conventions, I would assume that after you set the item selected, you need to call dataProvider.refreshAll(..). If it does not help, this could be also a bug in the mentioned component.

@knoobie

Should this be backported to V8 vaadin/flow#8548 or is the framework not affected by it?

Tatu Lund

@TatuLund

@knoobie , good catch, it possibly should be, I wrote adaptation of it (not just a cherry pick) vaadin/framework#12042

Knoobie

@knoobie

@TatuLund thanks! :)

@pleku

Hello. Anyone referring to listing components (like grid, combobox) using the interface type of HasItems or HasDataProvider to set the items to it ? Please comment if you do, thanks.

Knoobie

@knoobie

Only did it for internal addons where I wrote a wrapper for Vaadin components.

@TatuLund

@knoobie the PR #12042 was included in Vaadin 8.11.1 released today

@knoobie

@TatuLund Thanks Tatu! Gonna update later

hi! i'm trying to port vaadin 8 osgi portlet from liferay 7.0 to liferay 7.3.

https://vaadin.com/docs/v8/framework/portal/portal-osgi.html

java -jar blade.jar sh start https://repo1.maven.org/maven2/org/jsoup/jsoup/1.11.2/jsoup-1.11.2.jar

that used to work with liferay 7.0 but fails with liferay 7.3:

> java -jar blade.jar sh start https://repo1.maven.org/maven2/org/jsoup/jsoup/1.11.2/jsoup-1.11.2.jar
start https://repo1.maven.org/maven2/org/jsoup/jsoup/1.11.2/jsoup-1.11.2.jar
gogo: IllegalArgumentException: Cannot coerce start(Token) to any of [(Bundle[])]

→ the documentation should be updated because it talks about "Liferay 7+".

Tatu Lund

@TatuLund

@haba713 , which exact Vaadin 8 version you use? With Liferay 7.3 you need to upgrade to Vaadin 8.11, as Liferay kernel version was updated vaadin/framework#11943

Harri T.

@haba713

@TatuLund , I managed to get the portlet working with the help of Liferay developers at the Liferay Slack channel.

Harri T.

@haba713

Vaadin documentation:

java -jar blade.jar sh start https://...

That one does not work with Liferay 7.3 anymore.

You must use java -jar blade.jar sh install https://...and java -jar blade.jar sh start _OSGI_ID_ instead.

Tatu Lund

@TatuLund

Thanks, that is very valuable information, could you add it as a comment on the https://vaadin.com/docs/v8/framework/portal/portal-osgi.html page.

Harri T.

@haba713

I'll do that.

Harri T.

@haba713

done

hey all. is it possible to add a basic rest endpoint to a vaadin application?

Tatu Lund

@TatuLund

hey all. is it possible to add a basic rest endpoint to a vaadin application?

There should not be anything preventing that. REST end point will be served by its own servlet, so it is quite independent. You just need to verify that there are no overlaping servlet mappings.

Danny Ackerman

@dannyackerman_twitter

@TatuLund thanks! but how do i add another servlet "to the mix" that can also communicate with the vaadin app? basically want an external service to be able to call my vaadin server, which in turns pushes down info to all clients

Ghost

@ghost~5940038dd73408ce4f6704d7

@dannyackerman_twitter that is somewhat vaadin agnostic. first of all you will have a hard time to open up the vaadin servlet to do that

you can make your life easier by reusing something already there. e.g. if you use spring also add the web stuff and write some @RestController

then make sure your new servlet/controller/whatever and your vaadin application tap the same source

Danny Ackerman

@dannyackerman_twitter

hey all. anyone around who can help me understand a few things?

Ghost

@dannyackerman_twitter don't ask to ask, just ask

@christoph-frick i usually always follow that policy, it's just sometimes i'm looking for an interactive back and forth so its nice to know if someone's around to engage with :-)

@Gunmen-TT

Anyone, I have a question and need help

Widgetset 'com.vaadin.DefaultWidgetSet' does not contain an implementation for com.vaadin.addon.charts.Chart. Check the connector

I executed mvn vaadin:compile successfully and the file has been generated under the target, but the operation display still shows the above error

My license is valid

Tatu Lund

@TatuLund

Could you try mvn vaadin:update-widgetset and then compiling the widgetset again ?

@Gunmen-TT

Solved the problem thank you

@Gunmen-TT

mvn clean always deletes the AppWidgetset class under my target, and I have to go back to it every time. mvn vaadin:update-widgetset mvn vaadin:compile is there any good way to download this class?

Hey there, is there a way to fetch data from V8 Grid DataProvider without blocking the UI?

Is there a way to freeze the rightmost columns in a Grid?

Tatu Lund

@TatuLund

No, the column freezing works from the left. So freezing from the right is not supported. This has been asked couple of times.
