Great little demo app for Spring Boot + Vaadin!

I fired it up on cmd line on my Mac and saw three "boxes" in the top three buttons.

Loaded it into Intellij IDEA, and saw in the readme to try mvn install, still no images. Looks like it cannot find the fonts in the theme and I don't know how to install Vaadin themes, especially in a Spring Boot app.

The link to Directory's repo is required because of flow-viritin.
The repository is:

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

Looks like I have to turn MainUI into an interface :(

Looking at your example, would this be a way to add Spring RestTemplate like this example https://spring.io/guides/gs/consuming-rest/ for consuming REST APIs.

The goal would be that Vaadin would be for UI and consuming REST from other services.

for example when the birthday is 11/11/88 very strange

Tried to modify the master to support multi-entities for the below form but I get wrong number of type argument on ElementCollectionField. Do you have an implementation close to OneToMany relation for say User has Many roles?

Thanks for the example code here. My issue is probably related to: vaadin/vaadin-grid#199

The calculation of the PageRequest breaks down for me. Given the code

new PageRequest( offset / limit, limit)

For collection with 101 entries, the grid issues two requests when scrolling through the collection:

• offset=0 limit=40 thus page=0
• offset=40 limit=61 thus page=0

And consequently my table ends up with only 61 entries.

There is a suggestion how to handle this to be found here: http://stackoverflow.com/questions/30217552/spring-data-pageable-and-limit-offset

The following implementation appears to solve the issue for the small example I am working with at the moement. Needs more testing though. But maybe you want to a address this issue in the example implementation here. I feel that this is something most people binding to spring data will run into this.

import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;

/**

        // this is the odd case, when the offset is > 0 but smaller than the page size.
        // That means that there actually is a previous page.
        if (getOffset() > 0 && getOffset() < getPageSize()) {
            return 1;
        }
        return getOffset() / getPageSize();

Hello!

I am very new to Vaadin, and I have found your example very help in gaining a bit of familiarity with both Vaadin + Spring-data. I had a question about this chunk of code:

list.setBeans(new SortableLazyList<>(
// entity fetching strategy
(firstRow, asc, sortProperty) -> repo.findAllBy(
new PageRequest(
firstRow / PAGESIZE,
PAGESIZE,
asc ? Sort.Direction.ASC : Sort.Direction.DESC,
// fall back to id as "natural order"
sortProperty == null ? "id" : sortProperty
)
),
() -> (int) repo.count(),
PAGESIZE
));

If I understand correctly, this is what actually populates the MTable with data. I am trying to add another column to the MTable for instance a button that will link to another page, but I want that button for every row of data within the table. I am a bit confused about how you would go about adding such a column given this is how you populate the table to begin with. If you have any ideas that would be much appreciated.

Thanks!

When you set the below parameter on application properteis, I'm getting error n the screenshot ?

vaadin.servlet.productionMode=true

For prod, should I take this js and copy it to local ? Actually, I need to because my appl. will run internally, server doesn't have internet access..

When am running project am facing error Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessResourceUsageException: error performing isolated work; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: error performing isolated work

as i know @SpringComponent will use the default constructor,
how does PersonForm to inject below 2 parameters?
i didnt see any spring annotation for constructor

PersonForm(PersonRepository r, EventBus.UIEventBus b) {

have same question on MainUI injection

I tried to upgrade and I got

I am not sure where that is coming from right now but maybe that class does ring a bell for you?
