Validation icon not shown in Table fields

由 痞子三分冷 提交于 2019-12-10 19:49:07
问题 When I enter edit mode of my Table, I want the data validation exclamation mark icon (!) to be shown as soon as the user goes out of bounds of any of the validation constraints. First, a couple of notes: I'm using Vaadin 7, so the Bean Validation addon sadly won't work. The data validation works as intended. Now, I have a perfectly working table for which I am using a BeanItemContainer to keep my Person beans inside. The code for the table and the TableFieldFactory looks something like this:

How to make only some columns editable in a Vaadin Grid?

由 China☆狼群 提交于 2019-12-10 04:13:23
问题 Vaadin Grid allows to be defined as editable with grid.setEditorEnabled(true); This makes all visible columns editable. However I don't want the user to edit an specific column, but seems like the editable is an all or nothing. The next best solution I have found is to define an editor field with a disabled editor, which almost does the trick but the user is still able to select the text and move the cursor (but the field is not editable anymore). Grid.Column nameColumn = grid.getColumn(

Vaadin Custom Components/Widgets with Maven and Spring Boot

由 99封情书 提交于 2019-12-08 02:58:11
问题 I am relatively new to vaadin and started out with a spring boot application and the vaadin spring boot plugin. Everything worked fine until I got to the point where I tried to create my own components/widgets. Unfortunately I didn't find any "official" example/documentation how to set up custom components within a spring boot application so I had to search the web to find out how to set up additional plugin(s) in maven to compile the code for the client side widgets. As far as I can tell
