Is the tutorial on Spring for Vaadin 8 ?
Seems to be. Does the tutorial have some problem or error?
Yes, please see vaadin-bom part, you can see vaadin version in it.
Hello, wow… Johannes and qizer, Thank you! I am determined to learn Vaadin, it seems to be exactly what I have been seeking for a front-end to create Spring Boot database web apps.
I viewed a portion of the series of videos beginning with lead developer Pekka Hyvönen and Developer Advocate Matti Tahvonen - Streamed live on Mar 7, 2017.
And I love the tutorial given by ___ in the Seven Step Main Beginners tutorial:
https://vaadin.com/docs7/-/part7/framework/tutorial.html
NOTE: I went through the documentation for Vaadin 7 (even though I realize a little about the great improvements in Vaadin 8 – but without instruction, one cannot even begin to appreciate anything IF one cannot accomplish the very BASICS of data connectivity to a Vaadin Grid).
Please – SOMEWHERE between Step 6 (instructions OK) and Step 7 (instructions missing a few steps and does not work)
Can anyone direct me to the SAME instructions that can allow me to complete the SAME master-detail example?
My hope is to then to modify/upgrade that same example to connect to remote data, which I can do and currently use HTML tables to display the AWS RDS data. I want to learn and use Vaadin.
Please, can anyone review the current incorrect instructions and maybe provide directions?
I have found the Book of Vaadin, and have read a bit of it – I definitely shall read and study it, I would like to have the working example FIRST to use as a SUBJECT of study in my discovery and education of Vaadin.
If it is not possible, to begin with learning Vaadin 8, due to a lack of beginning instruction.
Please, can I put my Designer 2-week trial on HOLD, as I cannot use it with Vaadin 7 until I get to the point of completing the very first beginners tutorial?
Yes, I am going to explain in DETAIL right now, please allow me 1 hour to post back.
By the way, Johannes Hayry – thank you for your kindness, in a world of programmers that have no compassion for people and are condencending instead of being a leader. You stand out as the wind beneath ones feet – instead of an anchor around ones neck.
Thank you. The wonderful Paul Diaz is handling it, but IF I CAN just get the beginning trial instructions to work. Then I can begin to build upon that to learn. I have no problem with spending 18 hours a day to learn Vaadin, until I can transfer a basic POJO with a standard html table and TRANSFORM the bland to the Vaadin Fantastic with the feature of the Vaadin Grid.
PART 1 OF 2 - instructional error in Vaadin instruction
https://www.useloom.com/share/a08b011a6da74014a641011ddd5c6545
I can ask your trial be extended if you send me an email to johannes.hayry vaadin.com so I can see the email your trial is registered to.
Detail fields do not populate, no instruction provided – instruction is omitted

- data does not populate the detail form fields when focus is set to the master grid row
- form does not SHOW upon focus on a row within the master grid row
- some sort of date error in data connectivity

... 55 morePekka Hyvönen ?
https://www.useloom.com/share/5b10e39fc58149d684777380ef1b2230
I shall be in Helsinki later this year and hope to attend the Vaadin training.
Is this Pekka on the left?
ref:
Is the tutorial on Spring for Vaadin 8 ?
http://spring.io/guides/gs/crud-with-vaadin/
Thank you qizer, shall try that tutorial after accomplishing the very first beginners master tutorial
I began learning vaadin from this sample
You mention tutorial at address https://vaadin.com/docs7/-/part7/framework/tutorial.html , but that tutorial is for Vaadin 7. If you are starting new development in Vaadin I recommend learning Vaadin 8. That tutorial is at https://vaadin.com/docs/-/part/framework/tutorial.html
The videos presented in
https://vaadin.com/docs/-/part/framework/tutorial.html
are talking about Vaadin 7. Sorry about the inconveniece. I heard that those videos would be updated as soon as possible. So I recommend following tutorial text and sample code, but not following the code samples in the videos.
Hello, thank you for your reply. I was able to get the download version to work (example from github):
https://github.com/vaadin/tutorial/
Coming from a Delphi background, I had been moving into JSF. I realize that JSF beans are not compatible with Vaadin,so I am re-writing my beans for data connectivity right now, and then hope to accomplish populating a Vaadin grid with remote MySql data:
https://www.voxxed.com/blog/2017/03/21-improvements-vaadin-8/
Please any suggestions or examples you may share in accomplishing this basic development step, would be greatly appreciated.
Hi,
You might want to follow this guide:
https://vaadin.com/blog/-/blogs/building-a-web-ui-for-mysql-databases-in-plain-java-
. I just updated it to Vaadin 8.
