kandi X-RAY | csslayout Summary
Being a front-end engineer, I have to deal with a lot of layouts and components. There are a lot of CSS frameworks out there that provide popular layouts/components but I usually don't want to include all of them in my project. So I collect most popular layouts and components that can be built with pure CSS. They are powered by modern CSS features such as flexbox and grid. They are great starting points to be picked and customized easily for each specific need. By composing them, you can have any possible layout that exists in the real life.

QUESTION
I am a newbie to Java EE and JSF and I spent days on this issue without reaching any conclusion. Now I am hoping someone can give me a guidance.I have searched this forum on this problem, found some useful answers but nothing that could solve my problem.
I have a JSF page showing "parts" (part name, part number, part description, etc.) in a tabulated from using the h:dataTable tag. The rows all have update and delete links. When I click on the link for "update" for a given row, the boolean flag never toggles from 'false' to 'true' so for the h:inputText to render in the row, where I can update the part information. I see through the logs that flag is toggle from 'false' to 'true' but when the control returns from the bean to the JSF page, somehow (mysteriously) the flag toggles back to 'false', therefore, the associated h:inputText for update does not render and I cannot update the part information in that row.
The JSF page
ANSWER
Answered 2020-Dec-07 at 16:41Today, I looked into your code and it seems like an environment setup. I was able to update a part by clicking on the update link. Currently, your code has many pitfalls that might lead to errors preventing the container from rendering your application. You need to make sure to catch and log exceptions in your singleton. They are container-managed and they should not throw exceptions. In addition, before adding rows to the database, ensure the row does not exist. For instance, when you shut down the Glassfish server, it does not automatically shut down the DB servers, so upon server re-start, your tables from the previous run still in the database, and your code will try to load the rows once again from an XML file, which will lead to duplicate key exceptions; hence the Singleton let these exceptions to bubble up to the container level and your application will never start.
In addition, during the testing phase, when you manually adding data into DB from an XML file, it would be better to have the application to generate the PK for the entities to eschew duplicate primary key errors. For instance, when using Netbeans IDE in concert with Apache Derby, every time the DB server is recycled the pk generation starts from a set initial value after the application is up and running. In your case, say you loaded a row from an XML with PK=1, then on your next add from the application's JSF page, there will be a PK conflict with this existing row.
QUESTION
I am trying to write the watir code for the given xpath, but it's clicking the wrong button, the given below xpath works perfectly.
...ANSWER
Answered 2020-Sep-25 at 15:34The difference between the XPath and Watir code is how they interpret the "text" of an element:
- In the XPath,
//div[text()='#{locator.strip}']says that the very first text node of thedivmust equal the locator. - In Watir ,
div(text: locator.strip)says that the concatenation of all text nodes of thedivmust equal the locator.
As a result, you end up starting from different elements:
- XPath starts from
Title - Watir starts from
This difference results in Watir navigating to a different parent and then jumping over to the adjacent field.
Knowing this, if you wanted to be as close to your XPath as possible, you could add the class locator to the initial div:

I have a pdf reader developped using Apache PdfBox, my problem is that i have a blurry image after zooming , this problem is only with PDF even if the resolution is very good of the pdf file. this code working good with png or jpg files, but the problem still with pdf files, i'am really confused, i search on google but i found some solutions that are not complete.
Controller
...ANSWER
Answered 2020-May-11 at 17:43Use the two-parameter renderImage(page, scale) method. 1 is the default scale and is 72 dpi, 4 is 288 dpi which is usually pretty good. So I suggest you start with scale 4, and in a later step you increase when zooming (note that rendering may become slower with higher resolutions).
So a code example for your code would be

Answered 2019-Jan-16 at 05:09The layout components have changed in Vaadin 10+ from Vaadin 8. There are Vertical/HorizontalLayouts, but they behave slightly differently, since implementation is now based on CSS FlexBox. There are also API changes. CssLayout does not exists anymore, there is class called Div instead, which has replaced it.

I'm writing an Spring-boot application that needs to connect to at least 2 databases. I have 1 project per database in order to define their domains, 1 project per database in order to define their services and 1 Vaadin project for the UI.
...ANSWER
Answered 2017-Dec-01 at 14:18The last line of your stack trace is a clue: Not a managed type: class org.associative.domain.associativity.Parameter. Hibernate doesn't know about your Parameter entity.
In the LocalContainerEntityManagerFactoryBean you set packages to scan to org.associative.domain.authenticate. Your Parameter entity is not under this package.
This should fix the problem:

...ANSWER
Answered 2017-Sep-26 at 12:23Looks for me like your ComboBox doesn't have enough space.
Try setting mainLayoutheight like 200-300 px, and make sure your VerticalLayout main will give enough space to `mainLayout.
